[bob]

 

I was looking at the compatibility, and it only works with a few of my 
devices.  So, it may require something special.  I don't know what that 
special something is though.

Sorry Bob... 
  U r rite,,, without an FM radio module in device.. we can 
implement it... 
But we can add a new device  and writing a driver in kernel to work with 
the android . am i rite ??

Well, the first step would be to buy it and see if it actually works.

If it does, *then* you might ask how he made it.

thanks mr. Howard for your time, i don't remember what is "HCI

can't configure the BT or WLAN to use it and receive low frequency ?

[android-developers] Re: Fm Radio

[Bob Kerns]

I'm not about to spend my time on producing an example or even
tracking it down, as I just don't have the time.

But it looks like Gaz Davidson has tracked one down -- though it's
different than the app on my phone, which appears to have been created
by HTC. This is good news for you, actually, since the one he located
is open source!

You can't use the bluetooth antenna; that would be vastly too short.
It uses the headset wire as an antenna, which isn't really great as an
antenna, but is adequate if you have a good signal available in your
area. Just plugin in your headset! Phones that support this will have
the necessary connection from the headset wiring to the radio chip.

What do I think about this? I think it's a cool application of some
cool technology for constructing radios. Not terribly important -- FM
will eventually be supplanted by radio over IP, IMO, and I don't often
listen to it anymore. But cool, nonetheless.

The HTC radio app is pretty slickly done but basic. The Code Aurora
one I haven't seen, but from glancing at the code appears to have the
ability to record. I've often wanted an "instant replay" button on
radios like you can enable for TiVo (but is disabled/hidden by
default, grr...). Not that I have time to watch TV anymore either...

[android-developers] Re: Fm Radio

[Gaz Davidson]

The FM radio app which everyone is using was apparently created by Code 
Aurora 
(source),
 
adapted up by the MiUI team  (website 
is in Chinese, source is on there somewhere), then made it into Cyanogenmod 
(source ) and other 
ROMs.

I'm not sure how it works or exactly what firmwares are supported, but just 
by looking through the file names it looks like Code Aurora now have FM 
transmitter code working.

[android-developers] Re: Fm Radio

[Howard M. Harte]

The FM radio receiver is built in to the same chip that does the WLAN
and BT.  It is actually a third radio in those chips.  This is true of
the Droid X, which uses the TI WL1271 BT/WLAN/FM chip, and many of the
HTC and Samsung devices use the Broadcom BCM4329, which also has BT/
WLAN/FM.

I think vendor-specific HCI commands are used on the BT UART interface
to tune the radio.  With some kernel hacking, it should be possible to
snoop the HCI commands.

The FM audio out is an analog stream that is fed into a mixer, but it
is also possible to get digital audio out over i2s, and probably also
the HCI interface, but I dont think that method is used.

There is no FM standard API in Android, but it would be nice to create
one

do you can make me an a example code ? and a sketch with a example

[android-developers] Re: Fm Radio

[Bob Kerns]

Me, either. But I'll speculate as to how it works.

Phones are radios. The radio signal is processed and decoded into
audio, and fed into the audio streams. The mechanisms for this are
open source.

The FM radio signal is a radio signal that is processed and decoded
into audio. I bet it works much the same way.

So, if you're serious about figuring it out, I'd start by going and
learning how the low level phone access works (i.e. how the audio is
routed from radio to audio mixer). That part is open source.

Then I'd start reverse engineering, and find what calls the FM radio
app is making that are similar to how the phone works to set up the
audio stream for phone callls, and from there, I'd look for what's
different, that might be how it tells the radio what stream to route
to where.

I doubt there's an easier way to do it, if that's how it's set up to
work. If, on the other hand, it's just exposed as a separate device,
I'd look at what device drivers are added to the kernel, and look to
see how the FM Radio app turns it on and accesses it. (And the FM
Radio functionality does have to be specifically turned on by the app.
I'm guessing it's normally disabled due to battery consumption, but I
don't really know).

If you mean streaming radio, then you need to be looking up streaming audio 
in Android.

Those apps will use some sort of converter to encode the audio and send it 
out via socket to the app. the app will simply connect and play.

If you are looking for a streaming server, try Red5.

Well, I doubt HTC is going to tell you, so your best approach, I
think, would either to see what the people who integrated it on to
Nexus One did, or to reverse engineer the com.htc.fm app yourself.

I suspect that's more trouble than it's worth, as the result won't be
something that's supported, and will only work on a limited number of
devices.

I'm reasonably sure he means FM radio. Like the FM Radio app that
showed up on my Google Nexus One after updating with a MoDoCo build,
which uses the headset as an antenna, and the phone really does
operate as an FM radio receiver. Like I'm listening to right now.

Apparently the radio chip supports low-power FM transmit, too. I would
be curious if that has been through the FCC certification process, but
I bet it gets enabled in the non-stock builds soon anyway. Presumably

I have no idea of the API involved in turning it on. But once on, it
is fed through the Media audio stream.

The package name is 'com.htc.fm', so draw your own conclusions.

There is no FM radio in Android, period. Some Android devices may have
FM radio capability, via firmware modifications made by those device
manufacturers.

Even if there were FM radio support in the Android firmware, this is
the wrong list for it. Firmware questions belong on a list that
pertains to the firmware:

There is no API available for FM radio in android, but you can play

and there is a tutorial available in Android API demo to Play audio
