hi all
I've heard that Leo can play FM Radio without headphone work as an antenna? I wonder at it?
Is there anyone can confirm that....
Thanks!
Negative m8, Leo's FM Radio needs enclosed earphones handset to operate as an antenna.
I would love the day the manufacturers could put in a antenna to allow use of the FM radio without putting in a headset.
I hate using a wired headset.
Try one of these, no need for headphones and a bit cheaper!

Its a phone ffs, lol
Mind you they are getting bigger, so one day you could have a £500 fm radio with built in antenna.

i dont think its as easy as just putting radio antennas inside a body of a phone.
one might have to think about interference to/from the phone antenna, wifi antenna, bluetooth antenna, gps antenna and any other antennas already present in the phone.
I don't think it's even physically possible to make an antenna small enough to fit in a phone which is sensitive enough to receive low-frequency signals like radio.

Mmm..I dont know how to say but I just heard that from someone. They said Leo could play FM Radio without headphone in new coming Rom update. Any Mods here knows it?
It is not a bad ROM, it is because of radio-frequencies all need antennas that fit their special wavelength to work.
If you use radiowaves you can use antennas that are only half or a quarter of the wavelength, so 10cm waves need 2,5 cm or 5 cm antennas.
Radiowaves in FM are about 4 m wavelength, so you need 1 m antenna!

The FM Radio tool from the HTC Debug Tools (On the prototype phones) does work without earphones.
Also tried the tool in my release phone, als also there the fm radio worked without earphones....
just a few more months and the Sony Ericsson MW600 headset will be availlable with build in FM radio.. I have a SE HBH-DS220 at the moment and it works great sound is awesome..
I wish we could enable audioboost with A2DP

does it recived channels and you could hear it without head phones
i don't bother the built-in FM radio. Try use WunderRadio. Internet-based radio. Of course you need unlimited data plan for this to work.
Some walkman phones have built in fm antennas like w960, and some cheap chinese phones too, i don't remembor which one though, i read their test on mobilearena long time ago, so if it is possible.

That's great, except when you are on the move and lose data coverage which is exactly what makes the FM radio useful.
I just had the july 8 nrg rom in and the fm tuner would open & receive a few channels with NO wired headset plugged in & played it though the speaker..
I want to know if the fm tuner capabilities are based on the rom in general or a specific "fm tuner driver"
Currently on kumars 2.4.1 and of course the fm wont open without a wired headset plugged in : (
the hardware say there is a FM radio chip, but where is the FM radio?
do we need to install a FM radio program?
Sorry could you reference where it says that there is an FM Tuner?
I was under the impression that there wasnt one, its not listed on Googles specs for the N1
i saw it in another website , not in google specification

Indeed
Being an FM transmitter, does that mean its a receiver also?
EDIT: Nevermind, its both
That's interesting. Maybe they intend to use the FM transmitter for something interesting. Couldn't be simple as audio through car stereo on 88.7 and the like or could it?
Well, they might have just intended that to be for wifi/bluetooth like it is in the iPod Touch 3rd gen(same chip). But who knows, maybe they'll provide FM-radio support to the Android API some time down the road?
in the regestry edit you enter the section BCMSDDHD1 has any one noticed that the first 3 letters bcm reveals to the broadcom chip that exists in it as models from this company starts with 3 letters like (BCM4329)
and the only chip in this company that supports n wifi is the (BCM4329) that exists in the google nexus one and this chip supports fm transmition so
conclusion (if hd2 really supports wifi n type then it contains the only chip that supports it which is the BCM4329 that should support fm transmittence ) so if (wifi n) is really supported then the hd2 has a built in (fm transmitter hardware) that exists in the (BCM4329)chip so we hope to make an application to activate this option
correct me if iam wrong
what we have reached till now for developers
1.BLAST3RR have helped us with the datasheet in the attatchements for the broadcom chip
2. some tests are made to make sure that the hd2 has a really wifi n hardware and it seems that it supports it some what so we are some what sure that hd2 contains the BCM4329 chip as it is the only chip that supports wifi n type but we need live evidense
3. there are some pics of the internal components but it doesnot show the kind of the chip
4. xmoo posted a link to a cab that may help us in developing http://rapidshare.com/files/34053706...ebug_Tools.cab and here is the link of its thread http://forum.xda-developers.com/showthread.php?p=5446085
5.BLAST3RR reached that hd2 definitely has an audio path to the TX part for the FM radio, as it is listed in the 'WceSetAudioDev'.
Among the options is a 'I2S TX'. I therefore assume this is the path needed to feed the transmitter audio
6.useful files are added in attatchements fmradiosdk.dll & htcfm.dill to help in development
what is missing us
1. we only miss drivers for now
thanks you all for your support
i have posted a post in windows software development forum to ask experts to help us this is the post http://forum.xda-developers.com/showthread.php?t=624822

the fm transmittance antenna is in the broadcom chip(BCM4329) it self as it is said to has two antennas see this http://www.broadcom.com/products/Wireless-LAN/802.11-Wireless-LAN-Solutions/BCM4329
and rememper tp2 it has fm radio hardware but it was disabled until some developers enabled it by cab and disabeling wifi n in hd2 until a sutiable tweak to enable it (who knows why htc do things like this)
i hope this thread to be stickey as it will be ignored and we will never know the truth

Even if this is the case, I think the same antenna would be used as for receiving FM radio (the headset). So still, no worries as far as the aerial concerns.
This would probably require a driver to work first, though. Then the second thing to find is an application to send audio to it/control frequencies.
Anyone who would be able to develop such application will definitely get a donation from me.

but i think fm transmittance antenna is not the same as the fm reciver my frind has nokia n79 it needs headset to recive fm but it transmits without it
i think fm transmittence is direct from the chip as it has two antennas one for wifi and other for fm transmittence as i read before but reciving fm signals is through the headset as it needs longer antena

I know, but I was just stating that the aerial should therefore be no problem.
And that this would definitely be worth investigating.
When I had a Nokia N86 it had the FM transmitting aerial built into the battery cover.

Please forgive me/move thread if this is the inappropriate forum. I couldn't decide for 10 minutes, so I decided to go with the dev forum.
The FM radio: Is it going to be impossible to get it working on the N1? From what I understand the current state of play, devs have got the app working, it scans and finds stations, but it's as though the audio lines are physically not connected up (is this accurate?).
Could it be a limitation of the Alpha status of the Desire ROM being examined?
i think it is radio's fault
if google give us a new radio with fm and maybe some extra mb ram it will work just fine

I'm pretty sure the N1 doesn't have an FM receiver in it.
And if you don't have the hardware, you don't have the hardware. Software can't magically make up for it.
It'd be like trying to get an FM signal out of a toaster.

It has the hardware...there is a Gizmodo (think it was them) teardown of N1. Discusses the FM capabilities. Also...Desire and N1 have same hardware on the inside (different trackball feature and buttons..but the same). There are posts around the forums confirming this by Modaco and some others.

The Nexus One features a Broadcom BCM4329 chipset with "IEEE 802.11 a/b/g/n system (MAC/baseband/radio) with Bluetooth® 2.1 + EDR (Enhanced Data Rate), and FM radio receiver and transmitter" (according to Broadcom's product page).
It may not be fully connected up, or it may just be a software issue (hence my asking in this thread) but the hardware is in there.

What we need is the Desire's completed ROM, and might need it's headphone with built in FM receiver as well. When yo utry and open the FM radio app, it asks you to insert headphones with a FM receiver... well, some have tried and get it to lock on stations, but no sound. Which seems to mean it is a lack of a completed ROM/app, not hardware.
It's possible we may never get this feature working. Not a big deal to me, though. Pandora works fine!

The headphones don't have the receiver in it. it simply uses the headphone cable as an Antenna just like the iPod Nano's built in radio.

Yes and no... if the chip set itself has FM, which the Nexus seems to have, then this is true. But for many "dumb" phones it is the head set itself. This is why I said may need the Desires headphones, and then went on to say it seems more like a lack of a completed ROM/app, since you can tune, just no sound.

I'm not sure I would use the FM radio every day, sure, but it's an important feature nonetheless. For fast local news with minimal battery drain there's nothing like having a radio handy.
Many of the on-line radio services are great/better, but require you to use precious data bandwidth, and I resent that. I don't like the idea of my phone being a gateway for the phone company to make more money off me. I spend most of my life within wifi hotspots, and use the cellular web service as little as possible. Apps, audio books, and presynched RSS feeds can pass the remaining time.
For example, I was shopping for an iPhone in the final months of '09, and the cell companies all offered to "unlock" the GPS function of the iPhone "for three months for free". Hang on, I asked, the iPhone has its own GPS, so why a) would I need them to "unlock" the capability and b) I would have to pay for my own GPS after the first three months? I learned that, while the GPS coordinates come for free, the maps are the domain of the cell company. Screw that.
One of the best features of the N1 is the built-in Google maps, and while I might be willing to pay one-time for TomTom maps or software (the best GPS OS imho) but pay every month forever, no way.
I was trying to do a little research in to if I could get the FM transmitter/reciever to work or if it would be even possible. A little google searching around I found this. And the person who had been doing the most work on that part of android was an actual broadcom employee. So I sent him a quick, polite email asking him about FM support in the Nexus one. It is as follows:
"Mr. Harte,
I noticed your commits here. Will Broadcom provide support/drivers for the FM transmitter/receiver in the Nexus One and other Android devices?
Sincerely,
Will"
And his surprisingly helpful and quick response:
"Hello,
The FM receiver is supported in the HTC Incredible and HTC EVO 4G. I’m not sure if the Nexus One hardware supports FM. The 4329 chip has FM, but I don’t know if the external components required for the FM Antenna are populated on the board. I believe there is also some work needed in the kernel to enable the audio path for FM, but if/when HTC open-sources the kernel for the EVO or Incredible, this should be evident. Also, the EVO and Incredible use the Broadcom Bluetooth stack, while the Nexus One uses BlueZ. I don’t think there is any support in BlueZ for FM. I have no idea about FM Transmit, but I would highly doubt it is possible to get that to work…
-Howard"
That makes me sad but at least now I know. Hopefully though this will provide some light to any crafty developers interested tinkering with this.
Shorthand.
Even if the hardware says fm/transmit/receive, we would have to solder, replace the bluetooth stack, and possibly replace the chip firmware to get it to work.
Short, short hand.. NO FM on nexus one.
No really, somehow he neglected to mention the sister Desire.
Regarding the antenna portion, it's been proven that the nexus can find stations. . .just not output any sound from them.

Check the notes from Modaco's Desire ROM port. I think it's there. But since FM radio is analog, there may be a lot more to it than a stack.

Yup, his bluetooth doesn't work because he is using the Nexus One kernel. Well, we now know what part of the kernel isn't allowing the bluetooth to work; Bluez vs the Broadcom Stack. I don't know the legal implications of using it, but it seems like it would be possible.

Patently FALSE.
All we need is a kernel with FM support and the FM driver. Receive is definitely possible.
I do believe however that the power amplifier chips for transmitting are absent, so that won't be a possibility.

Getting an analog tuner that isn't connected to anything to tune is not much help. I don't care what software you write, if there is no output to be captured, it's not going to happen. It's like a cable box with no television connection. It tunes just fine. If the rest of the connecting hardware is there, then there's a shot. But Google has never said there would be FM in the Nexus One at any point. I am less than optimistic.

For the most part yes (esp. with those of us with froyo and flas ). But what made me start searching for this was a tornado that past by me by only a few miles. I luckily was in the car and able to tune in to a station broadcasting the Emergency Broadcasting Systems's message, but I thought it would be nice to be able to do that on my phone.

Integrated circuits perform multiple functions. That broadcom chip could do a lot more than blue tooth. FM is analog. If all you have is the tuner and there is no connecting hardware, then yeah, you receive a signal, but it's going nowhere. If you can't capture the output, you can't use it. Do we know if the FM radio signal in the Desire is ever digitized? It could work like a regular FM radio and the digital/software part is for tuning purposes only and radio itself is analog. I read somewhere is that the HTC FM radios require wired headset use - and don't play back through blue tooth. Irony there, I think. Speculation is that is because they are used for an antenna, but I think it could also be that it's because it's an analog output. I am guessing the N1 is missing all the required circuits - except the tuner.

This is true of the Touch Pro hardware at least. The FM Radio wouldn't function with out the headphones plugged in. It used the headphone wire as the antenna.
there is a great thread going in the nexus development area where some people are trying to write the kernel so that the sound has an output. It sounds like they are making great progress maybe anyone reading this thread who has some technical skills can help. I believe they too have been able to tune the phone to a station but not output the sound yet.
It seems to me we need definitive answers to the following 2 questions from HTC / Google ...
Q1. Does the nexus one have the necessary hardware and interconnections for FM radio reception and output through either the speaker or headphones. YES/NO?
Q2. Does the nexus one have the necessary hardware and interconnections for FM radio transmission of any type (music / voice). YES/NO?
If both answers are a definitive NO, we can move on. If there is a YES then the clever people here, who make the magic happen, have some hope of success.
Does anyone know the correct ppl at HTC / Google to ask these questions of?
I don’t have anything to add but would like to encourage you guys in your endeavour to get FM radio working on the N1 and also point you too or remind you what androidpolice reported at Google I/O
If this is true then perhaps all the building blocks are in place.

If both answers are a definitive NO, we can move on. If there is a YES then the clever people here, who make the magic happen, have some hope of success.
Does anyone know the correct ppl at HTC / Google to ask these questions of?

Or maybe we just need to think and use the info that we have in other threads on the subject. But I'll repeat things written in another thread, by myself and other guys:
Q1. Broadcom chip brief (the best doc available for it on the net) clearly shows the radio having no separate connections but using BT's high speed UART and I2C. The interconnects are the same, and since Paul's Desire port has radio control working - that means I2C is working too, so the answer is YES.
Q2. The stated output power of the chip is good enough for short-range transmission w/o a dedicated antenna, using headphone cord. The control and data are given in the same way as in Q1. So, the answer is YES again, but with more trouble - while there is a working device utilizing FM receiver functionality, which can at least theoretically be ported completely using its source, there is no device with FM transmitter, which means - if someone wants to use transmitter, that someone needs to acquire specific Broadcom documents for the chip.
So I guess the thread can be laid to rest, and anyone that can really help - for example, to go over Desire source and figure out the correct setting for QSD UART to receive FM audio and the procedures to stream it to the speaker - are welcome to head over to Dev section.
