fm dongle ??? - General Topics

i love that some htc phones have built in support for fm radio but needing to attach some kind of antenna wire to the audio port is a real pain in the ass especially since i dont have any hd phones so on top of the wire i need the aditional adapter dongle. i was wondering if anyone has made a small compact antena dongle that can just be plugged into the built in hd audio port

this a test of the emergancy bumping sytem

another bump test

that would be a good idea maybe if you have some broken headphones rip off the cord and just put the end in and see if that works.

headset antennas have never worked properly mainly because there is interference from the actual audio signels that are sharing the media. i am looking for a high gain dedicated antena circuit.

Radio FM

Is possible hear radio without cordless for example with a Bluethooth headset?
Like other HTC phones with an FM radio, reception is dependent on having the wired headset plugged in as it is the antenna for the radio. Without it plugged in, you won't get any reception.
I suppose, however I have never tried it, that you could stream the radio over A2DP to a bluetooth headset as long as you have the wired headset plugged in as well to act as the antenna. Maybe you could wrap up the headset and keep it in your pocket plugged into the phone - seems like a pretty bulky solution though.
Hope that helped - good luck!
Thank You PSARGENT but I tried already and donĀ“t work. Anyone knows any trick for it?
Also, if psargent's suggestion works, be careful that the headset you plug in must be one with a microphone built in (e.g. the headset that comes with the Touch Cruise) because it is the cable to the mic that is used as the FM aerial so a simple adaptor that just connects the audio outputs to a 3.5mm jack (e.g. the Boxwave adaptor) will not provide an input to the FM aerial.
Edit: I just saw that our posts crossed and that psargent's suggestion doesn't work.

This is the only part of the phone that I don't like. Why can't you use a BT to listen to the radio. Sure, I can see that it needs the wire for antenna purposes, but why can't you have that plugged in and listen via BT?
I install BTAudio, and hoped that that would solve it, but it didn't...

[Q] MicroUSB Headset/Charger?

Has anyone seen a microUSB dock/charger/headset that has audio capability as well as charging the phone? What I'd like is to play music from, have headset controls from, and charge the phone all from the microUSB port on the bottom... or is this what car docks are supposed to do?
The way my car is, it's annoying to plug in the charger on the bottom AND the line out on the top - if there's a headset/adapter type thing, I figure I'll buy one of those and build my own car dock, and potentially speaker dock for the indoors.
OR: Just a microUSB headset - maybe I could add charger wires to it...
Month-long bump: I've realized that all I want right now is a microUSB headset, like for the older phones with no headphone jack. Obviously they don't make these for the G2x; has anyone confirmed another LG headset that works with this phone?
I honestly dont know if anything like that exists but I dont think so because of several reasons. Just a few that come to mind I'm not sure if the kernel driver supports it even if it could; the power running parallel to the audio probably would sound terrible; the USB would probably have to be used with a USB (female) to micro-USB (male) adapter since if you were to find it, it would probably be for PC so needed to be converted further adding to the reduction in sound quality.
Silly question.... why not just use Bluetooth and then usb to charge/data only??
Not a silly question at all. I don't feel like paying for a bluetooth adapter but also, because I've had bad luck with them in the past, as far as sound quality goes; I wasn't very impressed. Are there any good/reasonably priced bluetooth adapters that you've had luck with?
The blackberry audio gateway has been reliable for me and sounds decent.
Hmm maybe... not really a fan of having to plug that in, in addition to my stereo. I'll keep it in mind. Any others?

3.5mm FM Car Transmitter Car Charger - Thoughts??

Hey guys,
Got a HTC Sensation, would like something which does
1. charge while in car
2. fm transmitter (I don't have bluetooth or aux in my car)
3. a holder in the car so I can use gps easier
I found this:
http://www.ebay.com.au/itm/3-5mm-FM...613695?pt=PDA_Accessories&hash=item1c1d79eb7f
Any thoughts??
Any other suggestions?
I'm in Australia.
Many thanks!
Since that one is a universal dock, it seems to charge from the bottom since most phones do. The problem with that is the Sensation's charge port is on the side.
Also, I'm very very picky about audio and FM transmitters nearly always produce static or some kind of white noise.
My solution/reccomendation for cars without an AUX port is to pick up one of these bad boys: http://www.ebay.com.au/itm/Car-cassette-Adapter-3-5mm-plug-/110650779646?pt=AU_Electronics_Portable_Audio_Accessories&hash=item19c34ce7fe
It's a cassette tape that provides you with an aux cable.
Then to cover your mounting needs, just get something like this: http://www.ebay.com.au/itm/Car-Mount-Holder-Charger-HTC-Sensation-Incredible-S-/190560511133?pt=AU_MobilePhoneAccessories&hash=item2c5e4aa49d
And it even comes with a car charger.
If you are worried about wires and want this to be a stationary installation, use black zip ties.
If you have any questions or want other suggestions, let me know.
Thanks for the reply constrabus.
Problem is...I don't have a cassette player in the car.
I got something similar off of amazon a few years ago for my MT3G. The FM transmitter worked just fine. I now use it with my Sensation 4G, but my newer truck has an aux. jack so I don't use the FM anymore. The one I got plugs directly into the lighter jack and then I run a USB cable from the side into my phone. I have had it for several years without a problem. Go for it.
I have a fm transmitter with a 3.5 jack I plug it in and it doesn't go in all the way and only plays the left side. Same thing on my EVO but on my transform it goes all the way in and plays both sides. Any ideas on how to fix it.

[Q] Stream cam to droid?

OK so I picked up a cheap backup cam that I want to put on the back of my truck. I would like to make it stream to my phone. My thought is to get a bluetooth transmitter to attachto the cam and have it stream to my phone via BT. Is this possible? If so does anyone know of a BT transmitter that operates on 12v and that I could hook the cam to? I think the cam has an RCA output and I know you can get an RCA to 3.5mm jack adaptor to plug into a BT transmitter. What are your guys' thoughts?
Good luck with that one.
LCD screens can be found for pretty cheap if you can't find a BT solution. Personally, I think a dedicated LCD screen would be more convenient then making sure you have your phone out where you can see it and opened up to the proper app.
Actually I have a car docking station that I usually always have my phone in when I'm in the truck so the phone is usually where I can see it. I had hoped I could set up an app in such a way that it would automatically launch when it gets the bluetooth signal. Yeah probably dreaming but thought this would be a good place to ask. Figured if anybody know how to do this someone on here would.

[HELP] headphones jack output burned out

While I was trying my car radio mods for a jack input, I probably make for error a short citcuit to some cable at 12v with my phone jack output
My phone crashed and restarted itself. All seems ok, but now when I try to use my jack output (for example with normal headphones) I have a lot of background noise, and when I try to turn up the volume above a certain treshold, I get a lot of distortion and the music is not "listenable" (simply horrible, only strange sounds distorted and so on..).
I have another photon Q (FAIL sim mod but working) and I was trying to see the resistence values from the jack output to the components near the output, but I can't se any differences with my headphone-broken-board.
The music works well if I use the internal speaker, the problem is only with headphone, jack output.
Someone can help me? Someone have the circuit of the board near the jack out to understand what I have burned out?
I hope so
Try replacing the jack from your other only held in with double sided tape

You might want to use a bluetooth headset with a headphone jack in the future. Just to make sure that the actual expensive thing won't get hurt.
With such bluetooth headset you don't even need the jack at your Photon Q
I assume that some resistor or fuse has been blown up.
But I don't have experience in such things.
thanks for your replies!
bluetooth is good idea, I was considering also a microUSB to jack out, so I don't waste energy for bluetooth connection.. do you know if photon q can handle jack out from microUSB or microHDMI out?
I have replaced the back cover with the other one of the 'good working' phone, but the problem is here.. I think some resistors or capacitor is broken, it seems a filtering issue or a output impedance issue.
I could remove resistors from the other board and solder in my board, but I don't know what is broken and I don't know the circuit logic.
would love to repair circuit, otherwise I could solder a micro hdmi/usb to jack out in the phone to replace the standard jack out.. ahah! But is not so easy
Over microHDMI it can but only digital, not analog. Useless for a car radio.
Never tried over microUSB. But I think it's also digital.
The energy which is lost because of bluetooth is not really more than the analog sound over the headphone jack.
Listening music for about 6 hours (with sometimes texting/surfing for about 50 minutes) I get nearly 40% battery used.
Bluetooth is on, day and night. As long as it is not connected to anything, the energy usage is nearly zero.

thanks for your info. I have never used bluetooth so much
But what about similar cables: http://it.aliexpress.com/item/Micro...er-For-Nokia-E52-E72-N900-8600/547805050.html
Perhaps some phone can handle analog output from microusb?
If photon q is able to do this, and if in that cable is not present some type of circuit, i can solder the correct cables from microusb to standard jack out. I could lose mic input, but I don't use it..
I'll try to find similar cables in my zone for testing, before buy it
edit: this thread is great http://forum.xda-developers.com/showthread.php?t=1321491
i think that soldering similar things in my phone I could never use my usb port for data again
for now I'll buy similar cable. I hope to find a way to repair my board anyway
If you have a microUSB cable, you could theoretically cut it and try it out.
But you need to know the correct colorcode for this cable, maybe wikipedia is useful.
Still, I think the audio over microUSB is only for the docking station.
(Never tried that, pure theory.)
This cable should do what you need: http://www.amazon.com/Motorola-Audio-Power-SKN6394A-Bionic/dp/B00H8YATYI
It comes with the original Photon Q car dock and when it's connected, the phone switches to EMU audio output - analogue audio output on USB pins.
I've done the coding work so this cable is supported in CM 10.2/11 (changes to kernel, audio HAL and framework).
I haven't tried to figure out how it's actually wired and what resistor values are used between what pins so the connection of this cable is recognized by the phone as there was no need for me - the cable I have works just fine. I can try to measure it if you need it, but I unfortunately can't promise when I actually find the time for it - I would need to make some preparation with usb female connectors I don't have handy currently.
Your issue sounds like you've damaged some part of the headphone amplifier. I don't know the hardware details of how it's exactly wired in the case of Photon Q. I suppose it's using a separate Speaker amplifier TPA2015D1 (as used in Atrix HD), but the headphone output may be coming almost directly from the WCD9310 headphone output. Not sure.

Thanks for your help.
I'll buy one of these cable for now, but I would like to repair anyway my photon Q headphone output.
I could find this WCD9310 in the board: I have a rework station so I could swap that chip from my other photon Q hoping to solve the issue..
But the output signal in headphones seems disturbed, usually I know that the digital electronics either works or it does not work .. it seems a problem of analog electronics, filtering or output impedance. I'm wrong? Or maybe within the WCD9310 there is some analog circuit?

The Qualcomm proprietary audio hub WCD9310 contains also integrated headphone amplifier.
See the MSM8960/PM8921/WCD9310 reference design schematics:
http://d-h.st/xJ9
Sheets 28 and 29.
You can see that there are only resistors and transient voltage suppressors between the headphone jack and WCD9310 HPH outputs.

You're giving me a great help, thank you.
Unfortunately I'm not so good with integrated circuit or similar.
What I can understand from the sheets:
- J6 JA13331-SW38-4F at top-right of sheet 29 is the jack output socket.
- Pin 1 and 4 are right and left headphone signals.
- As you said, the pin 1 and 4 goes to the WCD9310: HPH_LP pin 12, HPH_RM pin 17, and HPH_REF pin 18 (i think is the headset "gnd")
- As you said, between pin 1 and pin 4 of jack input and the WCD9310, there are only resistors, capacitors, and voltage suppressors.
So I understand: the problem are these voltage suppressors or capacitors or resistors or WCD9310 ! :laugh:
You said that probably is WCD9310.. you are more expert than me of coures, and I hope the only problem is the WCD9310 because is the easier component to locate and replace!
I could try to swap the WCD9310, but I don't know where is locate in photon Q, and all IC in the board are covered from metal cases.
I can remove all the metal covers from my 2nd photon Q until I find WCD9310.. but I'll destroy that board definitively.
It is possible that there is so little information on the photon q on the internet? I would like to find a circuit schematics, or at least an info about how the IC are placed in the board.
Good news!!!!!!
I have found WCD9310 in my broken board!!
I'll remove also the other two "capsule" and I'll make a detailed photo, it could be usefull for other problems :laugh:
