Maybe put FM TRANSMITTER FOR HD2/NEXUS ONE in the title

I vote for a better title also...
Make it clear, because this title sounds like a noob that do not search creating a thread that will be shut down in a matter of minutes.
Maybe something like: "We need help to activate FM transmitter in HD2"

Hey hoss, congrats on Egypt's great win yesterday.
Can you please use proper capitalization in the title? Like what zefiltrin posted: "We need help to activate FM transmitter in HD2".
I have an HD2 and it would be immensely useful to have an FM transmitter!

As I wrote before, FmRadioSDK.dll and HTCFM.dll are wrappers, not drivers.
HTCFM.DLL is wrapper of FmRadioSDK.dll. FMRadioSDK is wrapper of Bluetooth Stack.
Bluetooth stack decode data and forward request and hide all implementation details inside.
I bet HTC doesn't know those implementation details and broadcomm won't tell anybody (unless pay for it?).
we need to work on BT related files.
I posted key functions within FMRadioSDK in FM RDS thread before.
I think we have to write a tool to inject bluetooth stack/driver to see how things work.
The worst thing could be bluetooth stop working while our program control FM Transmitter etc.

we still need help so comon guys

Hello my friends,
Can you explain me why you want to make an FM transmitter with HD2 / Nexus ?
And what is the Mhz ?
22MHZ to 200 MHZ ?
Thanks a lot,
regards,
Nixeus

I can answer question #1 - simply because its,
cool, fun, and useful (in the car/hookup to stream your music to a sound system and you forgot the cable and maybe just got the headset)
regards

why are you askong about mhz it is the frequency of a wave but what kind of wave are you asking about wifi or radio or what

In order to transmit on the polices frequences or military frequence, or C.B frequence

An FM transmitter, as mentioned above, is useful for sending music to your car's radio in case it doesn't have an audio in jack or you don't want additional wiring.
As for the frequency, that would the regular FM channels' frequencies which fall in the range of 87.5-108.0 MHz. Ideally, if FM transmission was achieved on HD2/N1, it should be able to transmit at low power at any frequency falling within that range. The user would choose the frequency at which there is least interference in his location and use it to transmit low-power FM signals that his car can pick up.

I just played with FM transmitter feature of a prototype nokia phone.
Interestingly it prompts me to unplug accessories (headset) in order to enable FM Transmitter.
That means FM Transmitter is not using headset as antenna.
Looking at size of this device I don't think it use large/long internal antenna either.
Also read some internal documents related to broadcomm BCM chipset. Broadcomm provided SDK to manufactures rather than giving them hardware interface documents. The phone must sends a set of RAM initialization data to the BCM chipset after reset otherwise the chipset won't response to any commands.
In other word, we will need two things:
1. Find a device that using same chipset to provide FM transmitter. So we will know initialization data and control commands.
2. reverse engineer Broadcomm SDK/FM Radio on HD2 to understand the hardware ports.
After that it is possible to write a hardware driver for HD2.
ps. I think FM transmitter is useless. I have one at home. sound quality is too poor, even worse than WM radio. feels like a low pass filter.
And have to keep changing frequency when traveling between cities.
I spent £ 15 bought a cheapest mp3 in car stereo that supports SD card, USB drive and AUX input with many useful features, with expected sound quality.
If I spent a little more on that car stereo could come with A2DP so that I can use phone bluetooth as "FM Transmitter"
I only need it plays music from my key ring USB drive. threw my old Alpine stereo with that FM transmitter away.

This would be great! I could finally kick the ipod to the curb!

really will be useful
goooo....

funny i was just wondering yesterday about getting one of those fm transmitters commonly used for ipods, thinking it might work better than the poor sound i'm currently getting from the head phones i'm using with my leo.

would this be compatible with my TP2?

No you tp2 don't have a (BCM4329)chip so no go

Bluetooth music headphones

Hi Guys,
I have been on the search to find a bluetooth headphone that will allow you to listen to music through bluetooth on your I-mate/XDA 2 etc.
I came accross the Sonorix OBH-0100.
Site:http://www.sonorix.com/eng/sono_product_obh0100.html
Review:http://www.worldofppc.com/HWTests/openbt2.htm
I sent an e-mail to the company asking whether this set would work with Pocket PC (XDA 2). They replied back saying that current pocket pc's would need a A2DP (advanced audio distribution profile) to be able to use your bluetooth headphones to listen to music from your device.
Does anyone know how we could go about adding this extra bluetooth feature.
Im sure that alot of you would like this option / accessory. So if anyone could help that would be appreciated.
Thanks
Hi, well done on finding the BT headphones, I've been trying to find something like this for a while...
first, on other parts of this site there are links to the following place:
http://bluetooth.i-networx.de/index_e.html
This guy is busy writing BT software for the XDA to fill in the shortfalls, and slowly including more profiles into his BT tools, He may be able to help with the profile problem for the XDA...
Also, are they actually selling these units yet? The URL you supplied only seems to supply 'sample' sets for traders, I would like to know where it is being sold, and if not when it is being released if the info is available..
http://forum.xda-developers.com/viewtopic.php?t=6816&highlight=bluetooth+stereo
people say that the quality is horrible if it worked
Hmm I dunno, maybe it is possible to send the audio across the BT link compressed (maybe MP3 like) and do the decompression back into audio locally, this would possibly make it possible to send resonable quality over the BT link bitrate (I think it's about 700k).
Their website claims to have reached CD quality audio.
yeah suppose you could do that but it would require
a uncompression in the head set
it would be possible of cause but from that guy who tried it
it may require more then just a std profile
Yes, a special profile is required as mentioned in the first post, apparently it is an advanced audio digital profile (a2dp), but no hand held units have it yet, we were hoping someone may be able to write profile support for the XDA...
I sent an e-mail to Tobias at Pocket Bluetooth tools about these particular headphones and he replied that he has no ordered the headphones and will work on the A2DP profile as soon as he recieves the headphones.
Hope something good comes out of this.
Will keep you updated 8)
Great news, now we only need to sit back and wait.
I had a look at the site but they only seem to be selling trader samples? Do we know where these items can be bought yet and how much? if not do we know a release date?
No, they havent mentioned anything about a release date but I have heard that many people have ordered the trade samples to test them out.
I think trade samples is the ony way you can buy for the time being ...$220 is the price as I remember and this excludes delivery and tax that you might have to pay.
But I have to admit they look very cool and if Tobias can solve this problem soon, I would certainly order one for myself.
BT audio transport
Hi folks,
I'm on the search for BT headset that also plays back the audio output of my MDA II (e.g. direction info of tomtom nav 3 ...)´. When I found this thread I thought that's it, but there is now follow up after Apr. 24th.
Any news yet?
Still no news!?!?!?!
:x
what you need is a bluetooth profile which have support for
Advanced Audio Distribution Profile
ms really dont like bluetooth all that much and their stack lack most bluetooth profiles
maybe the latest vidcomm stack support it
more about bluetooth profiles
http://www.palowireless.com/infotooth/tutorial/profiles.asp
maybe you should look into this product
http://www.bluetake.com/products/BT420EX.htm
but some guy in the forum had one for test and said the phone quality was pretty poor
RE
OK guys!
A short review has been posted here:-
http://www.ppcsg.com/forums/viewtop...t=iphono&sid=6d3d546329a09353b6817f1c28cdca86
From another thread Pocket Bluetooth Tools doesn't work very well with iPHONO bluetooth headphone and the digital Bluespoon bluetooth headset. However, it creates a non-dynamic serial port and enables printing from the O2 XDA II to HP 450CBi bluetooth portable printer.

This is not a fm transmitter... this is a web-radio (to listen music via web, not to transmit over fm)

cant find anything to use in the diamond internally or by connecting up headphones as the antenna then transmitting. I need to know this urgently. Its in the N78 so why cant it be in the diamond? It receives radio frequencies so their must be a way to send

[HELP] Build :Dasaita Max6 digital output with volume control

Hi guys I am owner of a Dasaita Max6 with dsp, I would like to have a digital audio output to connect an external amplifier (helix, audison etc). You can help me (I have basic knowledge of electronics), perhaps from the dsp of my Dasaita max6 with an I2s to spdif interface? any forum user did this? thanks (sorry for my bad english)
hello,
there are quite a few solutions to your problem.
i'm using HELIX dsp; music transmitted via TOSLINK to dsp with UAPP and USB to toslink converter; radio, bt, maps via RCA analog input (no issue though, those are LQ signals).
you won't be able to transmit TOSLINK directly unless you know how to extract I2S data from ADAU1401 DSP (yet audio would be limited to 44.1kHz/16bit /android limitation/... so not the best solution).
to get digital audio OUT:
-use Universal Audio Player PRO; it provides 'bit perfect mode' so you get losless quality. it uses it's own USB driver to bypass android limitations.
-use USB to SPDIF converter. there are many solutions like I2SoverUSBv3 (one of the best quality; i'm using it right now); MCHstreamer (versatile); or devices like Topping D10s; E30 -very good DAC with spdif OUT (check audioscience for review). not sure if UAPP works with Topping though.
one issue that might occur - You'll have no software volume control if you'll be using 'bit perfect mode'.
my dasaita / UAPP has no software volume control at all (with or without 'bp mode'). so i need 'helix director' for volume control.
so in general - it's easy and it simply works
Hi ...........Thanks to TNSMANI for moving my post to a better section ,.
Thanks mahtew for helping me find an alternative solution and for the detailed explanation but I would like to have a real digital output if possible (this to have as few distractions as possible driving the car and not have other electronic devices to manage, such as space, costs etc) but not being an electronic technician but only an amateur (very amateur), I knew that from the dsp chip it is possible to do this, perhaps in this beautiful forum there is a technician who solves this problem ...... thanks
(p.s. excuse me for bad english)
you can belive me or not, but your solution will not benefit with much better sound quality. you will be limited to 16bit/44.1kHz which is limit for android sound driver. it might be good but not the best what you can achive. yet it will be better that RCAout
USB data is asynchronous so quite resistive to noise. USB converters are quite good. so you can get HQ digital source.
if you really need SPDIF out from MCU board, then you should find local workshop specialized in repairing electronic devices. it should be quite easy for him to extract i2s data [input to DSP]. yet keep in mind, that you'll still need RCAout for radio and other non android sounds.
.moved to MTCD..
Hi, let me explain better: I would like to know what are the pins (MASTER CLOCK [MCLKI] ,
BIT CLOCK [BCLK] ,WORD CLOCK [LRCK] ,SERIAL DATA [SD DATA OUT] of the dsp ADAU1401A (Dasaita Max6) to connect an I2S card to spdif
thanks

What does the Datasheet tell you? Were you looking for someone else to do the work and explain to you how to do it?
Here's the datasheet, all the info concerning interfacing to the ADA: https://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1401A.pdf
hello, thanks for replying, I only have basic electronics information, I do not have the datashet of the dasaita max6 but I think that the ADAU1401A has activated an analog connection of the front of the rear and of the sub, but is programmed to activate the I2s digital outputs ? if the answer is yes, what are the pins of the digital front? thanks

RDS info from Spotify

Hello everyone!
I have a PX5 radio dash unit with Android 10. There is a stock FM radio app which is capable of displaying FM frequency on the built-in display next to speedometer. Don't know exactly how it's done, I suppose it's communicating on the CANBUS. Original radio had also RDS displaying on this display. This display normally displays date and time, only then radio is on, it changes the purpose.
My question - is it possible to read the artist and song name from current played song in spotify to be displayed that way? Is there any possible link between these?
Car: Fiat Bravo II 2008
Best regards!

Hello.
Indeed, on my cars (Peugeot RCZ) happens the same. When the FM app is working the frequency (but not the RDS) is displayed in the monochrome display. As far as I know, the C Type screen allows displaying all kind of stuff (RDS, song name when playing MP3, etc...) so it may be interesting if there is some way to trick the CanBus communication for showing more info...

Can you share the picture of your CAN Bus adapter? Id very much want to find one that would allow the same on a Alfa 159 (Same OEM)

Why do the latest phones lack the FM Radio feature but phones from 2012 do?

Hello everyone,
I wonder why you can't listen to any FM Radio station with the latest phones when connecting some headphones (I personally use the Realme 8i) but you can with older phones. I love listening to my favourite radio station and I was able to do that with my old Samsung S3 GT-I9300 (2012). I don't understand why I need an app that requires an Internet connection to listen to my favourite radio station while I could do that with a pair of headphones. Can you please explain why I can't listen to the radio by using my headphones with modern phones, and tell me if there is a way to do that?
Thanks,
Chris

That's just sad...
More and more manufacturers no longer include the hardware chip in their new smartphones due to cost reduction considerations. In some other cases, various carriers even disable the functionality of the FM radio hardware to force users to use more mobile data.
