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

Oh well, i have a 3.5mm to fm adaptor from my ipod, and my cay has bt streaming (Thanks ford!)
Hi,
Does anyone know the read distance for RFID tags? I'm interested in using the phone to read inventory at our warehouse that uses RFID tags. If it literally has to touch it, does anyone have a suggested RFID tag reader adapter?
Ideally I'd like to read inventory when we deliver it, then output it to the web browser to use in our inventory tracking system. Thanks!
is it possible to add a non brand controller by it reading the indo from controller? like in this video for LETV phone

This is not possible without an IR receiver and afaik the 4c only has an IR blaster. If you can somehow determine the IR codes another way, there are remote apps that will let you import them, such as irplus.
Hi guys.
This is my first post and i hope i will not be shredded for being new.
I came here since neither google nore other forums nore youtube helped me with my quest, which is
to have an IR remote to controll aimp on my android device.
I only did find "make ir blaster" or app reviews, or Bluetooth related info.
There is a device called Flirc, which is a small usb stick with IR receiver.
It comes with software to bind the IR input received to keyboard/mouse commands.
The website says all devices that can handle a usb keyboard are able to handle flirc.
The downfall is that the software only comes for Windows/IOs/Android TV.
So i wonder if there is an android app which is homebrewn to make the USB stick of a use in
an android smartphone.
Other than that, i am happy to accept any hint for another method to
controll aimp or any other player vie IR.
IR is a must.
I can remember the ipod/iphone remote which was so easy to use (IR only).
So can u help me spread some light on this topic?
Greetings !

I got one of these ANT+ / bluetooth speed/cadence sensors for bicyling. I figured it would be a nice addition to keep better track of bicycle rides.
I enabled ANT+ on my xiaomi 9T, test apps can read the sensor... but then I'm stuck: what software supports it?
It doesn't seem google fit or mi fit support it. Strava removed support to directly interface with these sensors, so I would have to use an intermediate app to let Strava use it... bah. It seems like almost all android hardware is ANT+ enabled, but nobody cares to support it.
