FM radio ?

I've seen a few threads about an FM radio capability. Is this correct, that the hardware is there, but not used ?
I looked through a few tear downs and specs, but two of them contradicted each other.
Thanks !

from what i can work out, the chip is there, but not in use...hopefully some clever chef can unlock that module

I was wondering the same thing, hopefully someone makes an app for it soon

Anyone tried to install the Radio apk from HTC Tattoo on N1?

The broadcomm wifi/bt chip in N1 does indeed have FM functionality. It has never been tested (it was not a planned feature for the device and there was not time in the software schedule), so I can't guarantee it'll work, and somebody would need to actually do the driver work to get it going, but in *theory* it should be doable.

Could Google add support for this later or would it only be a case of the community adding it?
Does/would the SDK allow access to the broadcomm chip?

We (Google) don't currently have FM radio on the short term roadmap as a standard platform feature, so for now a community project would get you there the quickest.

Is there any documentation on the CPU that can help us code the driver? I can't seem to find anything

I have also been searching for FM Radio API and applications and stumbled across a couple of links that might be of interest.
The first one is a software developer who has got an FM Radio application running on android which has been written by Qualcomm and uses a beagle board as hardware.
i-miss-erin.blogspot.com/2009/08/listen-fm-radio-in-android.html
The second is from an android open source community. Actual source code is listed but I think it is written for a Qualcomm chip rather than the Broadcom one in the Nexus. Any code buffins able to tell us any more info from the source code?
codeaurora.org/gitweb/quic/la/?p=platform/packages/apps/FM.git;a=summary
I really want to get a FM radio app on my soon to be arriving Nexus. An FM transamitter would be handy too. Common Google even my old Nokia N78 has one!

Nice finding here. The application actually looks good but it won't run on Nexus. It uses android.hardware.fmradio class that doesn't exist on the current sdk (had it even existed?)

Have a look at
codeaurora.org/wiki/QAEP
it has more information about the community building these libraries. Here is a quote "MSM/QSD Android Enablement project allows users to build an Android based platform containing additional enhancements for Qualcomm chipsets. "
Hopefully they start making enchancements for the Broadcomm chipsets too.

An FM transmitter would prolly make me cry... would love to throw my ipods in a drawer and move on in my life lol

FM transmiter/reciver

It been reported thru several teardowns that the n1 has a fm transmiter/reciver inside. Is there anyway to to access this hardware (where would it be located /sys/device/ ect) would be nice to know if we can interface with this hardware.
nexusoneblog.com/blog/2010/1/6/nexus-one-dissected-reveals-80211n-wifi-and-fm-transmitter.htm

It would be awesome to actually have that funtionality. I've seen a few crappy flip phones with FM transmitters built in.

a google employee on this forum (swetland) said there is an fm transmitter/reciever, but google is not developing or working on an app for that yet, that's why they did not advertise it.

My nexus one is rooted and I have a console program just trying to figure out if this hardware would be listed in the /sys/devices/ area anywhere. Im new to android not sure of how the google api's work but would be intrested into trying to get a small app or script to run just to initalize the hardware and fool around with it. any ideas?

i know cliq users have a FM radio built in too, but they don't have an app to use it. see this here http://www.modmymoto.com/forums/showthread.php?t=526775

transmitter / receiver
does that mean it can transmit fm signals to car radio so we can listen to music?!

there should not be anything on the phone that you can find that mentions the existence of an fm reciever/transmitter... the phone has one but there is no functionality of it because there is no driver or app support for it... from what i have gathered getting the thing to work is going to be quit a project because the community would have to create a driver for the device as well as an application that calls on that driver as well as utilizes the capabilities of the chip itself... i dont know what experience you have with creating a driver to work for a complex piece of hardware that you have no idea how it works, its more/less going to be like blindly threading a needle unless google/htc would be so kind as to give one of our lovely coders some groundwork...

potentially... if this thing gets coded to work, receiving signals will prolly be the easier thing to figure out first...

other HTC devices, such as the HTC Touch Pro2, have a built in FM receiver. HTC actually writes an app for this and I use it on my TP2, but I don't know if one exists for the N1. You can search xda-developers for the win-mo version for the TP2, but my point is, if they did it for winmo, they can do it for android!

lol clearly you did not read get my point... "they" are not making anything, else they would have marketed it from the get go... it is up to the android community more specifically the nexus one community to come up with a driver that makes the chip functional... the chip in the other devices may be different as well, aka different driver needed...

What about htc tattoo? It has a fm receiver and an app...

The nexus one uses the broadcom BCM4329 Chipset. I need to find something to work with for this chip to even understand the funconatly of the chip itself I will look thru broadcoms site later see if they have any kind of driver or any information at all on this chipset. Reading other posts on other phones that had a similar chipset people were able to get the reciver on the chip activated but were unable to get the sound routed to the phone. They were able to however to get the the radio to tune to certain frequanceys and I think get the RDS information from the chipset. If anyone finds any relevant information post it here
Nycro

This tree was just added to the android source on the 12th of Jan looks to be mostley for the WLAN/Bluetooth features of the chipset

Looks like an fm radio app for android using a qualcomm chip.

Im talking with the devolper of the driver for the wifi portion of the chip. At this time he is as well intrested in getting the Radio part of the chipset working but does not know much about it himself. Hopefully something will arise out of this conversation with him and maybe we will get a nice start to getting this portion of the chip working!
Im new with programing for android so I probley will need some help in the end lol.. allthough im pretty adaptive with c++ and some java im not no expert (Bacholers in network secuirty)

Clearly, you didn't get my point. For the TP2, not only was the Radio app not marketed, it was also not made available by HTC, but is now available on this forum. Secondly, I didn't contest that Google is not going to develop a Radio app - I simply said that HTC HAS made one. Hopefully, that clears things up

I have been talking with the guy from broadcom tongiht i will quote some of what was said here. Im not sure if he wants to be know to the comunity or not.
He had included the link to a video I have seen on this fourm will link below.
"I'll let you know when I figure something out. What other HTC phone uses the 4329 chip with Android? I wasn't aware of one. The HTC HD2 WM6.5 phone uses 4329, but I don't know if FM is enabled on that either.
There is an Android FM radio app for the BCM4325 chip, I saw a YouTube video of it running on a BeagleBoard: ww.youtube.com/watch?v=v6wdTOHrwQw This is using an AzureWave module, which has the 4325 in it.
The FM RX portion on the 4329 should be the same or nearly the same. I believe the FM is conrolled by special commands in the BT HCI interface, so some Android framework/JNI work might have to be done to the BT stack."
Thanks to Mr H ^^
I will do more work on this tommorow and see how far I can get
Thanks for everyones intrest and help!

An FM APP to unlock the FM Radio functions of my Nexus is something that I am willing to pay for!!!!
Some of the senior developers here are aces so I will keep my fingers crossed.

I just want to express my interest in a FM radio for Nexus One.
I think people (including me) will be happy to pay for an app that enables the FM reciever on the phone.
Good luck to whoever is trying to get this to work!

As I am not a developer all I can do to help is surf the web to see what I can find.
I found this link tp://www.9to5mac.com/broadcom-BCM4329-iphone-802.11n-FM
That states the iPhone has the BCM4329 chip in it. Now I have not found an apple app nor do I know if this helps any of the aces out there.
So just take a look.

Froyo FM radio? what gives?

I thought that was appart of the update? I don't seem to have that? Is it like the trackball that they released the driver/api and some dev has to make a app to use it now? I was hopeful for the transmitter more than a reciver but I guess I am a big dreamer ;-)

That was never confirmed to be apart of the update - it was simply speculation that evolved into false hope.

Do we know for sure that the FM hardware exists?

Can you provide a link to where/when Google stated that it would be part of 2.2?

Yes we do...
Oddly, an app called "HTC Radio Info" is in the manage applications, all tab. Not sure if this has already been discussed?
Anyways, it was never confirmed, just speculated upon. And if it is an API, then I am sure we will see something come of it in due time.

Well, I have been skeptical about the FM radio because of the chip name.
"Of interest is a Broadcom chip labeled Broadcom BCM4329EKUBG. Why? Well, the BCM4329 (albeit, without the "EKUBG" qualifier) is capable of 802.11n (HTC only lists 802.11b/g) WiFi in addition to FM transmitter and receiver."
The chip name is not the same as the one with FM t/r but has been said to have it, which is pure speculation.

But the Nexus One DOES have a wireless N radio and you can connect to N only networks.

Yes, and in addition even if the chip supports it the fm radio section might not be connected. On these types of devices that have fm receivers they are usually wired to use the headphones as an antenna since an fm antenna is far too large to fit in the device. Ours might not have that much needed connection.

IF we got it this would not be the first device I have owned that a supposedly not working/not connected fm radio module suddenly became a working/connected fm module. Not saying one way or the other but its absence is not absolute proof.

Paul from modaco has managed to get it to tune into stations, but just not get any audio out.

It has a precedent, though - update for HTC Touch CDMA (HTC Vogue) enabling GPS receiver that was unused until then, existing in Qualcomm MSM7500 CPU of the Vogue.
So it was done before. The question is - would Google bother or would they just skip it and leave it to the community (if it's feasible at all, given that Desire has the same chip and connections - which isn't confirmed).

Thats what I mean I had a touch diamond NAM version with supposedly no fm because of some hardware deal and sure enough despite HTCs assurances that it could not be done the community got fm going after a time. I would bet there are other examples besides these.

Bluetooth 3.0 is a lie

Go to the bluetooth menu under ##DEBUG# with 2.2.1 and you'll see it says BCM4329 which is a 2.1+EDR chip. Right under that it will flat out say "BT_SPEC_VERSION_2_1".
Edit: Sorry for posting in the dev forum, I forgot I was still on there.

No. Epic 4G has bluetooth 2.1 and other galaxy s's have bluetooth 3.0. Simple is that and samsung did not lure about that.

Hmm, what chip do the other phones use?
Also, what's this supposed to mean? https://www.bluetooth.org/tpg/QLI_viewQDL.cfm?qid=16676

However, I noticed that the BCM4329 family does claim to have both FM receiver and transmitter capabilities... but then I guess that doesn't mean this particular chip, by the way it was worded - I hope it's not just wishful thinking

A lot of phones have FM chips disabled. The Nexus One has this same chip actually and a lot of people tried getting FM transmitting to work but I haven't seen anything yet.
I emailed someone at Phonescoop and they say the phone has Bluetooth 3.0 and linked me to the same certification site I posted previously.

Isn't Bluetooth 3.0 effectively do authentication via bluetooth and send file over wifi? not to mention not too many devices support it :/
Bluetooth 4.0 introduces most of the goodies.. like low power mode..

Is the Iconia FM Radio capable ???

Hi there would love to listen to FM radio on my Iconia, does the Iconia have the necessary hardware/chip to be able use some of the hacks that have been done to enable FM on some Android devices ??

nope
You would have to use a external tuner.there is no audio in port on Iconia that I know of so don't know if its possible at all.but lots of FM radio stations broadcast off there websites. I think thisnis your best option

Thanks for your reply Erica, yep I know there are apps for streaming, but I wanted to do a custom install in my Nissan Navara truck and use purely FM and RDS to save money on streaming data...
Any ideas anyone?

You can't as Erica said. The tablet just doesn't have the FM tuner that you would need.
EDIT: You asked for an idea so here's one. Buy a radio. You won't be able to play radios on this tablet without streaming the music to.

well officially it doesn't have FM radio support, but like the phones I'm pasting below these dont either but have the hardware to do it but are not enabled in stock and have been made to work, what I'm asking does the iconia have the capability like these phones?
Quote :
Spirit FM Radio is most likely to run well on CM7 ROMs with the CM FM app, but is also reported to work well on some MIUI and other ROMs.
Experimental Galaxy S support for Darky ROM, and CM7 and related ROMs has been pulled.
These devices have been confirmed to work well:
TI chips: - HTC Legend - HTC Tattoo / Click - Sony Ericsson Xperia X10 mini (Stock ROM rooted. Not mini pro, yet) - Motorola Droid X (some report problems, but others seem OK)
Broadcom chips: - HTC Desire / Bravo (GSM only) - HTC Desire Z / Vision / T-Mobile G2 / Merge / Sprint EVO Shift 4G - HTC Desire HD / Ace / AT&T Inspire 4G - HTC EVO 4G / Supersonic - HTC EVO 3D - HTC Google Nexus One - HTC Touch HD2 / Leo - HTC Aria / Liberty - HTC Wildfire / Buzz - LG Optimus One / P500 - LG Swift / GT540 - Dell Streak (Only from speaker so far, not headphones)
These devices have not been confirmed, but supported the CM FM app (as of May 1st) and are likely to work:
Broadcom chips: - HTC Glacier / T-Mobile myTouch 4G - HTC Incredible / DROID Incredible - HTC ThunderBolt / Mecha (Scorpion) - Geeksphone Zero - Motorola Zeppelin
These devices will be better supported as I continue to add support for Silicon Labs FM chips:
- Samsung Galaxy S/S2. - ZTE Blade / Racer.
These devices contain Broadcom chips, but appear to be unable to receive FM. They show unusual RSSI values, that jump rapidly between such values as: -128, 0, 16, and 55. None of these devices have a stock FM app, nor will any other FM app function. My theory is that these devices lack the hardware connections to operate, and may even be deliberately disabled:
- HTC Google Nexus S (Has no Silicon Labs FM chip, unlike Samsung Galaxy S.) - Samsung Galaxy Tab - Samsung Galaxy Spica i5700 - Motorola Atrix 4G
These devices do not seem to function well for unknown reasons. Hopefully they will be enabled in future:
- HTC Desire CDMA / BravoC - Samsung s5570 mini (GT-S5570) - Sony Ericsson x10 mini pro
These devices seem to function well but audio has not yet been enabled. An analog audio routing method may be discovered, or digital audio (when supported) may help resolve this issue:
- Samsung Galaxy 5 / GT-i5500 and other Galaxy 5 series devices with MAX8899 audio chip - LG Optimus 2X / Star / Speed / P990 - Wits A81E\G (WG7310) (FM Antenna must be soldered)

CM7 runs gingerbread so we can stop the discussion right there.
Even if you would have such a chip (which would require tearing the device and checking it or getting your hands on a Tech manual) you'd still need the software which we don't.
So until we get some developers that made the app for CM here and someone to port the app to Gingerbread we won't be able to do anything even if we had the correct chip.
