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

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
ttp://android.git.kernel.org/?p=platform/system/wlan/broadcom.git;a=summary
Have a look at.

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.

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
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?

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.
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.

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..
Samsung Fascinate have Fm Radio, but I don't find app its. Can I set app for my Cell. thanks
Huh? Could you reword that question? Its hard to understand what you mean.
Although I think this is a General Forum Question, I think he is trying to say.... "The Fascinate has an FM radio, but I can not find the App.... Where can I find said app to use the FM radio..."
Answer: Doesn't exist..
there is an FM radio in it?
Don't you think thats something they would advertise?
Highly doubtful
If there is a FM capable chip on board, we currently don't have any apps for it.
I don't believe that we have a FM chip in this phone.
I found on gsmarena the specs of this phone and realize that the phone has "FM radio with RDS". ^^. lol.
http://www.gsmarena.com/samsung_fascinate-3492.php
Could this be a feature that froyo will enable? I seem to remember this happening to a friend of mine when his incredible was updated to 2.2; he got the radio & the flashlight.
Sent from my SCH-I500 using XDA App
it would be a nice little addition, however I think I would still prefer pandora or one of the many other internet radio apps.
The FM radio was listed on the first pre-release spec listings, but was removed from later listings. The prevailing theory is that the Fascinate was originally going to have an FM radio, but it was scrapped (like how we were supposed to have Media Hub like the other Galaxy S phones but are stuck with VCast). I wouldn't count on the hardware being there. The Incredible's FM tuner was functional with 2.1 (I can vouch for that firsthand).
FM radio stations are lobbying to make FM radio receivers mandatory in phones in the US (in exchange for paying higher fees).
Because of that, several phone manufacturers and chip makers have had the hardware put in their devices as a just in case measure. For instance you may find a Broadcom chip that controls the wifi and phone radio to have an fm receiver as well. In any case, these specifications sometimes fluctuate.
However, without actual drivers to run said unsupported tech, the issue is moot.
Swyped w/ XDA App. When in doubt, mumble.

These chips have support for alot of features that the manufacturers dont utilise, unfortunately. since the S2 does have an fm reciever, hopefully it should just be a matter of tweaking it to transmit a signal? funny thing is the chip also supports Bluetooth 4.0, wonder if that means we'll be able to update to 4.0 once its officially released.

no it will never get activated just like the previous versions of samsung omnia hd
It will maybe never get activated by samsung, but what can we do about this?
Is there an possibility to activate the transmitter and what do we need for doing that?
Maybe if we find a phone with activated transmitter (same chip) and software it would be possible (but i dont know an android phone whit this speccs).
This feature would be making this phone perfect for me (because i use it a lot on my old nokia n85) and i am not the only one who would like this.
yeah would be pritty good but dont think its gana happen ... :/
It depends on wiring of the hardware! If you have a chip which includes a transmitter than you have only one part of an working transmitter. The other part is a antenna connected to the chip and maybe an amplifier between them. If the "transmiter output" ins't connected to anything then there is no chance to use it...

Probably not connected by samsung. I recall the hardware is also capable of more than the supported signal bands, but samsung chose to not use that feature.
Ok guys, what's new about FM transmitter on our sgs2?
Please, can someone try to start developing something?
Our s2 is getting smarter and better day by day
Send from my Samsung Galaxy S II
a chip being capable of and the whole parts doing the stuff are 2 different things.
In the broadcomm's datasheet there are all the things that the chip is capable of doing it.
But, let put it this way: The chip is capable to use 3g network but in order to do it you need a 3g radio part in it.
The same with the fm transmitter. In order to use that feature you need a real fm transmitter in the phone, a radio transmitter, a piece, a device, a part, you get the point.
And i am afraid that our good old SGSII does not have a fm transmitter in it.
