FM frequency transmitting software - Tilt, TyTN II, MDA Vario III Windows Mobile ROM De

Its just an idea. I dont know if it is possible with kaiser or not. But I have feeling that it might be possible.
Is it possible to make a software that can transmit a song using kaiser on FM frequency just like those external FM transmitters for car? I think it is possible coz Kaiser already have the radio wave transmitting device inside it since GSM network works on radio frequency. But I might be wrong. So just a question for those genius minds here at XDA
Life would be so easy if this is possible. You go into the car start a song on your kaiser and bingo!! it is connected to your car's music system without any hassle of wires.
Just an idea,
Regards

dude u need fm transmitter - something like this http://www.solware.co.uk/fm-transmitter/
it is a hardware issue not software!!
this thread should be in kaiser general or at most kaiser software

Man... you are completely wrong. Kaiser (like any other cell phone) have radio for communicating with GSM / UMTS baseband stations, BUT. But that radio operates on ABSOLUTELY different frequency! FM radio works on 89-108 MHz, GSM works on 800/900MHz - 1800/1900MHz and UMTS even higher! Despite of this great frequency difference it operates with different modulation, different width of channel and especially it operates in digital mode (instead analog as in case of FM radio).
So... it would be nice, right, but it is absolutelly impossible. It is possible as you would try to beam a light with microwave oven (light is electromagnetic radiation and microwave oven produces that, right?)... just forget it

I know about those hardwares but I was talking something different. Probably I wrote it confusing so you couldn't understand my point. But anyways it is not possible. Wish it was possible. You can't imagine how easier life would be with that thing possible.

I dont believe it is absolutely impossible, just highly unlikely. It has to do with whether or not there is an oscillator in the phone capable of creating something as low as 88MHz. I have no doubt the phone could do something as simple as fm modulation, am modulation would be even easier.

we all wish that but we also know its impossible
but if four of us (kaiser owner) met we can build a baby microwave rom our phones check this out http://www.youtube.com/watch?v=lg_dyD0Nsjw

Nokia has this feature?
I think the newer Nokia phones have this FM transmitter capability. Although it's really just another "feature" to hammer the already p¡ss-poor battery life on Nokias!
Don't worry... I won't be heading back to Nokialand for this. The N80 was enough to send me to Windows Mobile for the forseeable future.

There are baseband filters to cutout noise and harmonics to maximize phone output and minimize those bad harmonics (ever heard about SAR? ) so... NO is the simpliest answer. The best choice is to either buy that motorola gadget / Car Radio with bluetooth receiver, or build your own car audio system (i am planning to do so)

Hows the FM Radio?

Well my pair of fuzes should be arriving on Monday or Tuesday so I'm beginning to wonder about some of the other hardware parts. I keep reading that the FM Radio uses the headset as an Antenna. I have a Hermes and the included abysmal headset that came with that, and I have so little intention of using the one that I'm about to get it might make small children cry, so heres the question of the day:
Does the FM Radio work acceptably without the headset? If not, does it work with an adapter and *REAL* headphones?
Not a deal breaker either way, but it would be cool to know.
Hi, I've a Touch Pro on Vodafone UK flashed with ROMeOS² Italian Rom (just to let you know ). I'm using on it the headset controller that i had with my previous phone, an O2 Stellar (Tytn2) and a Sennheiser CX300. Absolutely no problem, and the sound looking great!
Now on your other questions.FM Radio is not working without headset, so you have to put them in the plug, and then FM Radio program will start. Otherwise, if for you is a problem having headset inserted in the phone, you can buy an headset controller (on ebay have a really low price!).
About the headset quality, I had before of Touch Pro, a tytn and a tytn2, and can confirm that the quality is the same, so I never used those!
PS: sorry for my english, I hope you undertand what I'm saying!

I live fairly close to New York City, so this may in fact be a YMMV. How far off are most of your radio stations?
better then the diamonds radio
Radio program works great for me. It just depends on what kind of area you are in like the poster said a few above me with buildings in NYC. Headphones are ok that I got with my Hermes.
The other route to take of course is streaming radio but that will probably take more battery life than FM.
i DL the one for the fuse and my headset doesnt work as an antenna..... i wonder if i used another phone headset if i could pick up any other radio stations????
is there a cab file for the fm radio?

I recently was passing by Phoenix AZ and picked up an FM station when I was about 150 miles away and held it until I was 150 mile past Phoenix. Maybe the conditions were just perfect, maybe my headphones are a very effective antenna but whatever the reason, I was impressed with the performance.

It works great, you need a adapter for your headphone though. It comes with the phone.

Strictly speaking that's not true - mine works fine on 'speaker mode' with just one of these in it.
I use some retractable ear buds (also from ebay) & it works fine. I get a good signal on most UK stations of note.
I also stream world radio from the links posted here here, which is fine for talk radio even at GPRS "2 bar" speeds using Windows Media Player and in comparison of course, the FM player is much better.

Actually, I misspoke. I was thinking of digital radio, which many stations are now supporting and is gaining some popularity (as far as broadcast radio goes) in the US.
FM radio is a dying breed in the US, not just because of MP3, but because FM stations have been hijacked by corporate radio (i.e. Clear Channel) which limits stations to tightly playlist controlled "formats" - Emetic Easy Listening, Soporific Soft Rock, Headache Metal, Un-hip Hip-Hop, The-Same-30-Songs-You-Heared-3000-Times Classic Rock...

You know, its funny, but i had a $99 LG prime, prepaid phone from att. It has an fm radio and doesn't need the head phones as an antenna. So it is possible. I don't know why all phones don't have it..... that was the only good feature about the phone, and its reception was awesome.

Because it's ineffective. Having an antenna equals more signal strength in radio. If you live in middle of a city, then I would not think that we need an antenna.
Looks like the 20 last years of my life the technology did great things but unfortunately the IQ of ppl drop dramatically.
The only thing that mobile phone companys should do is to create cellphones with build in antenas of the best quality materials and make those antenas able to extend. ffs. U can do it easy and ppl will buy easier.

[App Request] FM Radio transmit / full band receive

Hi all.... this is not your usual "I want to listen to FM on my otherwise unsupported ROM" request. What I'm requesting I think would be far more interesting, and if applied properly, could benefit many makes and models of phone. For that reason, maybe this belongs in an even more general forum, but I'm starting here because this is the phone I have and I don't know just how many other models use this same hardware.
I see that the HTC Doubleshot / T-Mobile MyTouch 4G Slide, along with several other phones, has a BCM4329-B1 radio chipset. This chip is reported in many places to be capable of not only FM Radio receive but also transmit. Unfortunately, that's as far as anyone goes with listing what it's capable of doing. Partly because of this (and partly because of search overload or maybe me not knowing what terms to use in my search), I can't find specs enough on the chip to know the full range of frequencies it receives. I have seen enough to imply that the same chip handles bluetooth, wifi, as well as FM broadcast band. Something as widespread as that might just be capable of extending receive capabilities outside of the usual broadcast band (for instance, maybe it can be used as a "police scanner" of sorts).
If nothing else, I think it would be fantastic to have an APK that can take MP3s or perhaps any kind of streaming media and retransmit it, low-power of course, to a nearby FM radio set to receive on the same frequency (much easier to get e.g. Pandora into every room in my house this way). I just figure if I'm going to ask for this I may as well ask for the world, right? Of course I don't expect a multiband ham radio to pop out of my phone, but if I could use it to maybe pick up a wireless microphone at 181 MHz, or act as a frequency meter (similar to WiFi Analyzer apk) for low-power transmitter troubleshooting, that would be phenomenal. Icing on the cake would be the ability to record what it receives, assuming it receives outside of band (record-to-file equals record-to-stream, here, meaning also record-and-serve-on-a-wifi-or-4G-link).
Any takers?
I wish I could offer time and skill but I just don't know enough about development nor does my life lend much in the way of free time for hobbies... I'm hopeful someone else has already thought of this.
Regards and TIA

I have a unique position on this, because it's a problem I run into consistently.
When i'm doing this and can't hear anything around me, and the camera gets no music when it records.
The only good way to deal with this without getting a noise disturbance violation at night is to use a couple of androids to sync all the music up - person(s) on camera has a device with headphones, sync up with the one playing music next to the camera.
There is no smooth way to handle that in random locations all over the place, way out of wifi range and possibly with no cell service as well.
There is no easy answer but there are ways of making it work. I'd write up a guide on how we do it now, but being down to only one device I can't run through it in front of me now, i'll have to wait until I see my friend again so we have two or 3 machines to use at once or I get my hands on another one (hopefully soon - this is my biggest aggravation with being temporarily down a device, no bluetooth or interacting with another device testing)
Since someone else in interested in the exact same issue here i'll take the time at some point to sit down and recap what worked or didn't work and link to the things that did. Have to be another day though, i'm pretty tired now and gonna catch some sleep soon.
Anyone else put effort into something like this?

ah HAH! I WONDERED what you had for a "day" job!
Joking aside though, I'm surprised out where there's no cell signal they worry about noise violations... Here, there's a time limit (15 minutes at a time with at least I think a 5 minute break IIRC) but you can make noise pretty much any time at night. Just don't wake the neighbors up and nobody complains
Thanks for posting your thoughts. I'm willing to test insomuch as it won't risk the device. I just don't know enough to program my own app for this...
...if it's even possible: a guy at work reminded me today that just as CPU manufacturers use the same chip designation to indicate a CPU with and without features like L2 cache, phone mfgrs like Samsung (he has a not-so-new Galaxy phone) have been known to use this same chip with the FM radio capabilities completely absent to the point that someone in the know actually removed the chip from his device, hooked it up on a bench, and was completely unable to get it to do anything FM radio related. It may be that while some iterations of the chip overall are capable of being made with transmit, that it's quite likely transmit itself was left out of the hardware itself.
I'd still like to see if it's possible. Maybe if the chip identifies itself in the OS, we can see how it does, and maybe it will hint at whether transmit was included or not.
Found this:
http://forum.xda-developers.com/showthread.php?t=1042094
Which implies this was originally touched upon before the Evo... However, it also provides enough info as to say the only FM receive/transmit this chip will do OOB is FM broadcast band (76-108 MHz). Still, it can transmit...
Bump!!!!
That would be ill if you could transmit on FM band ...... anyone make any progress?
Although why not just stream via bluetooth? what would the advantage to transmitting on fm band be other than epic nerd street cred

Fm xmit might go farther, especially if the right antenna can be made.
Fm can be simultaneously received by multiple devices. Think here tv-out to a small portable projector showing the latest theatrical releases in full composite glory and stereo sound out of the viewers' battery operated headphone radios all while offering 4g data hotspot... :~/
Honestly, the real reason for me is the fm radios in the garage are louder than the portable computer speakers I've been playing Pandora through and I hate the dinky transmitter that came with my wife's ipod because it only does 4 stations high in the band. This would make that much easier (and I'm sure many others would find a use for this).

HTC DoubleShot /T-Mobile MyTouch 4G Slide running Bulletproof
FM Transmit:
I get asked this question regularly, and my response is generally: "Forget about it, almost no Android phones connect the FM Transmit pins anywhere useful".
But a few months ago a helpful person sent me an HTC FM transmit app. Apparently it was meant for the T-Mobile/HTC Mytouch 4G, and apparently that device is supposed to have the transmit pins connected.
I have no idea (yet) if that is true or if this also applies to the "Slide" variant.
I'm sure this will only work on ROMs that use the Broadcom proprietary Bluetooth stack and that have sufficient parts of Sense present. IE, a stock or stock derived ROM. It probably requires Froyo or GingerBread.
If anyone has or can load such a ROM and wants to try, and will commit to reporting their results, email me at mikereidis AT gmail.com and I'll send the APK.
Thanks...

That's exactly what happens on my Desire HD and Desire Z running stock derived Gingerbread.
The success report for the non-slide phone was on Android 2.2.1. I don't know if 2.3.x is possible, but I'll find out when I get my myTouch 4G HD hopefully by the end of the week.
I expect to add a transmit test function to my FM app Spirit at some point, and it will then likely work on any ROM, though audio routing could be a challenge.

I get the same exact scenario myself. I even went to the extent of making sure I had some audio playing to make sure that it wasn't just the fact there was no audio and it might have been waiting for it. still no joy. It appears that the slide variant of the MyTouch 4G does indeed not have the Fm transmit pins connected. then again, I have not looked at my logs yet, so I do not know exactly what it has been doing.

The logcat doesn't show any errors with executing the FM Transmitter app. What I can see is the FM Reciever gets activated on the logcat. I should say that FMTx & FMRx cannot be run in the same time.
1. So the error could be the FMTx got killed by the FMRx intentionally.
2. BCM4329 driver doesn't have the code to interact with the FMTx chipset.
If the mt4gs does indeed have FMTx on it's chipset then I'm sure it's working/connected on the board else we wouldn't have any FM Radio on our device.
Bluetooth, FMTx & FMRx is located in the same part of the chipset. One dies then all of them dies.
Now anybody here could link me to the stock kernel of the device which made this work? I could look at the bcm driver on that kernel and maybe I could hook it up on the mt4gs kernel to make it work.

Ok guys confirmed! Hardware should be capable of transmitting fm frequencies.
Looking at the data sheet FM Tx & Rx are bidirectional which means as long as FM Rx is working so will be Tx.

Now the problems left would be the driver & the Hardware Abstraction Layer(HAL). Since we already have an FM Tx app.
LOLcat ?
Yes, the 4329 has TX inside, no problem, but I'm pretty sure it can only transmit or receive at one time, never simultaneously.
Every time I've looked at the internals of the Broadcom proprietary Bluetooth stack I've seen the transmit function, and HTCs implementation tends to include that, and their own mods.
The biggest issue should be whether or not the Transmit pins are connected to the headset. Heck, most of the phones with this chip don't even connect the receive antenna pins. (IE no FM radio whatsoever, grrr, what a waste.)
That said, I'm not quite sure why the TX app hangs on most phones, other than the plain myTouch 4G. There might be some difference and I hope to get to the bottom of it.
And eventually, I should be able to make Transmit work on any BCM4329 device with the transmit antenna pins wired, but there will likely be very few such devices.
And before anyone asks, it will likely be completely infeasible to make the hardware mod needed, same as for FM receive antenna pins.
I see 28 downloads of the FMTx app now.

Hi! As I said if FMRx works then should be FMTx. So it's clear now that hardware wise FMTx should be fully working. Now software wise that I still don't know.
Regarding antenna I'm not quite sure if it's really necessary? You see I have a device here Nokia N900 which has a built in FMRx & FMTx feature which was really implemented by nokia. And I already dissassembled it alot of time to the point I know each and every part of it And I can activate it's FMTx without the need of a headset. I just need to play the music player select the Transmit FM option and select the frequency I want then I can channel the music to any radio reciever 1 to 2 meters away from me without the need of an antenna.

Yes, the CHIP has all the hardware needed. But the most important "hardware part" is the connection of something to the FM Tx antenna pin. Even if the pins aren't grounded (Which tends to kill all chance) and left floating, the chips are inside "RF shields" will just about kills any chance of reception/transmission.
Every radio receiver or transmitter MUST have an antenna. On some devices it may be internal and you don't see it, but it's definitely there. On old AM radios internal antennas were a LONG piece of wire wrapped around a bar (ferrite?).
In some cases, an antenna is just circuit board traces. For high frequencies, such as cell or GPS or Bt/WiFi only very small antennas are needed. For lower frequencies, like FM around 100 MHz, the best antennas are roughly the length of headset cables.
This could possibly be coiled and wrapped around something and hidden inside the phone. But it's there, no way around needing an antenna.
I have some phones that do remarkably well with no wired headset for an antenna. But an "antenna" of sorts is still there, even if it's only several millimetres to centimetres of circuit board traces meant to connect the antenna pins on the chip to the headset.
Yeah, LOLcat. when you go into command prompt, "adb lolcat" is the same as "adb logcat". Apparently, the team at Google said "logcat" so often and so fast it sounded like "lolcat" to them.
Mikereidis is correct, you do need an antenna, even if it's hidden. Otherwise you have extremely high standing wave ratio (SWR) that will eventually fry your transmit amplifier. This is basic radio theory at play, that one learns when becoming FCC licensed radio operators like General Radiotelephone Operator or Amateur Radio Operator (I'm the latter of these, KE4EDD, though I haven't picked up a transceiver in about a decade).
Like he said, it's not as critical at higher frequencies because wavelength (and therefore necessary antenna length) is shorter and can be hidden inside the device (take the cover off your MT4GS and you'll see three separate antennae all up around the camera lens -- they're just thin sheets of metal on this phone).
Still, the pinout of the chip itself is important. This I know nothing of as I haven't seen it. either way, if the spec sheet says Rx and Tx work on the same connections (e.g., they both require the same pins to be "high" in order to physically activate either mode) then all we need is to get the HAL and driver set up. I know nothing of this as well. Wish I could help. All I can do is offer my phone's lolcat services.
On that note, I received a <sisa:###:##:#::#> text message this morning, appears that it's a T-mo thing, that T-mo is trying to update my phone (which is running a custom ROM), and now my digitizer doesn't work, so I may need to hold off on even the lolcat until I get it fixed.

you do need an antenna, even if it's hidden. Otherwise you have extremely high standing wave ratio (SWR) that will eventually fry your transmit amplifier. This is basic radio theory at play, that one learns when becoming FCC licensed radio operators like General Radiotelephone Operator or Amateur Radio Operator

I know the theory, but I've never believed that low power, under 100 mw transmitters get damaged too often. But I imagine a final output transistor on a chip can't take as much abuse as an external one.
cj chitwood said:
Still, the pinout of the chip itself is important. This I know nothing of as I haven't seen it. either way, if the spec sheet says Rx and Tx work on the same connections (e.g., they both require the same pins to be "high" in order to physically activate either mode) then all we need is to get the HAL and driver set up.

Documents about these chips are "very secret". I can't even find much on Chinese sites that specialise in proprietary documents. The official vague block diagrams can't be trusted either.
But if the transmit and receive pins were the same pins, I'm pretty sure we would have achieved FM transmit long ago on the most popular Broadcom chips, on devices that support receive. That said, I think the much rarer Qualcomm Tavarua chips use the same pins, and there are no transmit reports on them.
I've looked at schematics of some phones, and I've seen FM antenna pins specifically labelled as "Rx", so that's another clue in favor of the idea that Rx and Tx pins are different. This might also be easier to achieve on the chip.
I wonder too if it's easier to achieve FCC etc certification if the hardware design specifically makes FM transmit impossible.
I'm certain it is easier to achieve, as long as they can certify to the FCC that no more than so many milliwatts will be pushed out. Then again, with as many transmitters as there are that are available to the public, it can't be that hard to do.
We keep talking about Tx and Rx pins. In my limited experience with chips, I'm wondering if these are antenna pins, or activation pins. I also wouldn't be surprised if it was that some chips have a mode select pin (high is one mode, low is another) that could be labeled both as Tx and Rx, and each mode requires a separate other pin to have a certain voltage on it to provide power for that section of the chip. Alternatively, to have two mode select pins, again whichever one is hot selects the mode, and the third pin provides power for both modes, and thus is labeled Tx Rx even if the mode select pin isn't attached.
Either way, if pinouts are so secretive about this, it's pointless to discuss pins because they literally could be anything. I think however that you having seen the innards and/or schematics of these devices means that you would know more than I as I have yet to even crack mine open
Oh and the lolcat thing... no, you really can type "adb lolcat" in command prompt and it runs a logcat. The explanation for this was literally that they said "logcat" so fast it sounded like "lolcat". I am fully aware of the meme, http://icanhascheezburger.com and have forwarded quite a few on to the wife even.

FM Radio tuner NextRadio (snapdragon)

they claim the snapdragon version of the note 20 ultra has FM radio, but NextRadio is dead and doesn't want to work on the phone even tho it comes preinstalled bloatware. Ive tried versions 3.xx/4.xx/5.xx ( i get frozen screen)/ and 6.xx, the closest i can get is one of the first builds of version 6 will let me get around the no network error or not supported screen but shows nothing tuner related,almost like there is no FM hardware enabled. I am using the samsung/akg provided usb wired headset and a cheap amazon throw away set just to be sure.
Has anyone gotten the FM tuner to work on this device?
Same on my note , no FM radio .
Sent from my Samsung SM-N960U1 using XDA Labs
It needs more than just the radio to make it work. The other stuff needed has not been present since Samsung(OEM's in general) moved away from headphone jacks. Also this requires testing as well as licensing(pay Qualcomm for licensing, and then governmental body for testing).

ive been out of the loop with this stuff for awhile, did Samsung disable the FM (software sided?) or did Qualcomm (hardware sided?)? Im kinda curious if a new developed app could get it to work. or is there a way to see what hardware is present or disabled?

It's Samsung and hardware. If you don't connect the radio then it'll never work. Doesn't matter if the radio is within the chip. You also need an antenna which isn't present internally. Also in the US there is not Note 20 with testing done for the fm radio.
It's safe to assume Samsung didn't pay licensing, didn't connect the com for the radio with an antenna component connected, and didn't have FCC test the feature.
This is driving me nuts. I researched before this Note 20 Ultra 512GB came out and read that it will have the FM radio but only in the Snapdragon version which is what I have here in the US. I did a trade in of my Note 8 which worked fine with the FM radio. I even bought an adapter for the charge port for the wired headphones. Now I've lost the Note 8 with radio functionality to a trade in. I'm so mad. I used the radio to tune in at conventions to a local unused station that the convention used so I can listen without distraction and record the talks with voice recorder for later listening, it recorded the radio station directly. This was very important to me. Someone from SAMSUNG chat help said there is no FM chip in the US models. The NextRadio app says can't access the FM function and to tell my carrier I want access to it.
What is the deal? Does it have FM or not? If so, does Verizon need to activate it? I just can't seem to find a definitive answer and cannot find a code that works to find the secret menu for this phone via the phone app. Please someone help.

Sorry man, it doesn't look like it is the case. I went through this with my unlocked Note 10+. I was even hoping that the T-Mobile version would have FM because the previous CEO made it a mandate for phones on the T-Mobile network but they must have quietly let that one go once the headphone jack was gone. My S10+ has a connected FM Radio but not my A71 5g.
Thanks for answering. I just wanted to be sure as I don't always trust support people. Half the time, by the time I reluctanly call or chat support for anything it's because I just can't find the answer and it's something beyond what these "tech support" people have scripted for them. They just wind up frustrating me more.
After posting this I tested the adapter for the headphones in my mother's Note 8 with NextRadio. No sound with NextRadio. Only when plugged directly in to the 3.5mm jack. So, even if there was FM on the Note 20 Ultra, the charging port headphone adapter theory won't work.
Tempted to write the FCC to get this mandatory but will probably be a waste of time. I'll just get an mp3 player with FM radio that will record from the radio and have to carry another device around on those occasions (at least a clipon or armband). Most of the ones on Amazon seem to be Chinese made and I am concerned about the quality and reliability. We will see.
Thanks again.

Question Which UIS7862 unit should I buy?

Im looking to get a new head unit for my car (Corsa D 1.2 2009), and was planning on getting the Teyes CC3. I then found out through this forum and elsewhere that its essentially just being resold? I then found other units like the Mekede M6 Pro, etc. Im not sure which one to get, does anyone have any suggestions? Or information that can help me decide between all of the UIS7862 out there?
Im leaning towards the Teyes even if it is slightly more expensive, as ive heard good things about their support and firmware updates.
But ive seen units for £180 (6+128gb) with better spec than the teyes at £250 (3+32gb)!
I mainly want good audio (so a good DSP and AMP chip), and i want polished looking software and not having to deal with the android stock menus as much.
For someone in the UK, what are peoples suggestions?
Thanks
Gershy13
Mekede M6 Pro (Youtube, another UK guy like you). Personally I would never buy a T'eyes. Too much closed source and paid software.

Thanks,
Would you be able to tell me what the main differences between going with teyes and their closed apps (some examples of why theyre worse) compared to something that isnt locked down? Like mekede or anything else.
Another one i found is OSSURET? I was thinking of the S8

It seems to have a slightly higher clocked processor too. And for the same price as the mekede i can get maxed storage and ram. Thoughts?
Are you planning to listen to FM radio? If you are I advise you to stay away from any FYT based head unit. If not go ahead.

Curious as to why? But no never planning on using the radio. (Spotify only)
AF function (changing frequency of radio station when signal gets too weak to a stronger signal) doesn't work on FYT head-units. If you're in a country that doesn't use DAB this should be a deal breaker.
Wish I knew that before ordering mine, but I didn't even know it was an FYT head unit. xD
Also be aware that the Bluetooth pairing functionality is quite unintuitive to work if you plan to share data via bluetooth from your smartphone. It does not connect automatically so you need to connect manually every time.

Ahh okay thanks. That's fine I don't mind using WiFi for internet sharing. Or even usb if it's supported.
And yeah no plans to use the radio so we're good.

are you sure about that, have you tried https://forum.xda-developers.com/t/...nd-sc9853i-fyt-devices.4387965/#post-86251871
Also, the BLuetooth on these units, comparatively, is very good, with proper BLE support via dual Bluetooth to support things like radar detectors (Valentine One.)

Yes, I am sure. Go over the thread and Kotix explains it why he can't fix AF.
He made a work around for an user to easily switch between saved frequencies of the same radio station. But this is manual switching that an user needs to do by himself, not automated. This is not optimal when you're driving.

My Bluetooth connects immediately every time I enter the car.
I also find FM radio to be excellent using NavRadio+
AF isn't a deal breaker for me. I only have 1 station that jumps between frequencies occasionally (BBC Radio 2) and Kotix workaround is intuitive and easy to use.
The fact that it doesn't affect doesn't mean the issue isn't there.
Bluetooth works well. Bluetooth 2 doesn't. There's the simple work around of automating an wifi hot spot when your phone connects to Bluetooth.
It's true the NavRadio+ is a big improvement but the AF doesn't work at all.
My bluetooth always connects to phone 1 but if you have phone 2 it will not link to it, you have to pair it manually even if it has been conected previously. That's a shame.

Same here - second phone never connects automatically. Really annoys me because we are two daily users of the car :/
Yeah, I know your pain lol. I suppose the manufacter would need to invest on a better bluetooth chip for two phones to work. I come from a Pioneer with bluetooth from 2008 and it already allowed to pair 2 distint phones at the SAME time!!! And it still works.

A recent thread addressed this and a reseller replied with a config.txt that seemingly results in the Bluetooth trying the last phone used and failing that trying the next phone in the list.
Does Bluetooth only reconnect to the last device used?
My unit allowed me to pair multiple phones (my wife and daughter also drive) but the Bluetooth system would only reconnect to the last phone used. So if I drove the car last, and then my wife drives, it won't connect to her phone without manually...
forum.xda-developers.com
I can see a few lines that might be relevant but I've no idea what the secret sauce is to change the behaviour.
Backup your current config.txt and give a few of them a try if you're confident.
Lines I can see that "might" relate to Bluetooth pairing...
ro.build.go_lasttop=true
sys.fyt.bluetooth_show_voice=true
persist.btpair.ssp=1

Hum... thats interesting stuff. Thanks. I'll do a little more digging and give it a try if I discard the chance of bricking something.
