Hi Guys,
I replied to this quote, then realised that I'd never seen the iROCK! mentioned generally here:-
I have an early version which works great either battery or car adaptor (tho never in this country obviously!!! :wink: )

I'm trying to use my XDA2 as a MP3 player and want to take an audio feed from the XDA2 and put it into my hifi. The only way I can think of is to use the internal serial port and convert it to twin phono's but not sure if this will work. Any bright lights out there know the answer?

You could also try the amazing iROCK! which you plug into you earphone socket & it transmits on one of 4 FM frequencies to your nearest radio.
(it's illegal in the UK unfortunately, but available from USA etc.)
Don't know where you are located. If ya get caught over here, I never suggested this Guv! :wink:

Got mine from a visiting American, only use it 'on the move' :twisted: Not suggesting anyone else do the same, of course.
you can get these on ebay, I bought 2, shipped from hong kong
Quick question - They all seem to have 3.5mm jacks. Is there a version with 2.5mm jack?
you can get converters from 2.5 to 3.5 many many places

Has anybody tried the car baby? its small rechargeable unit that clips over the speaker and transmits on fm band, all audio will then come from speakers in car or in house on the radio. I found it to work well as long as you kept the volume low on the pda as too much volume causes distortion. It is very cheap and very effective as a wireless audio transmitter and doubles up as a hands free for the phone also.

Thanks for the input. I am not sure which generic 2.5 to 3.5 works and which does not. Obviously the 2.5 jack in the XDA has the extra contacts for phone off/on button. Does this cause any issues? I think I have seen a reference where the poster was mentioning hearing both left & right channels mixed on his right earphone when audio is piped into a good quality headphone using a 2.5 to 3.5 converter.
i doubt it but not 100% sure
i got the original QTEK converter myself
came to me an idea to connect the music player in the phone to the FM radio in the car to play it ! I'm very positive for it .. since getting TMC from the radio to the gps software (in this thread) , so there is a possbile connection between them ? the question, could someone came with a software or hacking can do this ? with no need to buy external FM CAR KIT device to make it works !
I hope yes ...
Thanks ....
im also looking for such an app..
i had also put down the same question here
Hi, i think you don't really understand whats meant by RDS/TMC through radio. It doesn't get information from your car-radio, it's a build-in radio device within your phone. And this is even a receiver, not a sender. As far as i conern there are onky three ways to connect your phone to your car-radio and all of them are the way 'music from phone to radio'
1.) bluetooth, but only a few radios have got it
2.) via fm-transmitter which is a way whichmostly shold work
3.) vie line in at car radio and line-out/speaker-out/headphone at phone

2.) HOW CAN U CONNECT "via fm- transmitter "? ?
Hi imrock,
ask google for it or even ebay. ;-)
1. buy fm-transmitter
2. plug in fm-transmitter to device instead of headphones
3. search for the frequency on which your transmitter transmits at your car radio
4. enjoy
I don't have experiences on my own, but a few weeks ago i've seen a test in a magazin. They summorized as follows: The quality of music is not really good.

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!

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 : (
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.

I do remember reading about that. Can you find the source? If thats true, then we know the only problem is the stack.

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.

or you can go to your favorite radio station's website and click on "listen in" or whatever and now your listening to FM on your phone. =D

i dont understand what the bluetooth has anything to do with this? why does it matter the blueZ vs broadcom bluetooth hardware? it sounds like the fm radio portion is there and can even pick up stations with an antenna, just routing the audio. but that doesnt need to happen thru bluetooh, it could happen through the headset or loudspeaker.

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.

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.
Hi guys
we knows that we have to but our headset to run the Radio because it is working as antenna! but if we have a good signal we dont require headset can some one make it working without a headset?
How you come to the conclusion it will work without antenna?
Haha lol. You want the impossible. Maybe you could also find a developer to transform your mobile into an airplane our something like that.

take your home radio. cut the antenna. do you think you will get ANY reception? the error in your thought is that you obviously think that the headset cable is just to improve reception and that the phone's internal antenna is also for radio reception but you are wrong. it won't work!
the solution is an internet radio app
It works instead! I tried it with a single connector without any cable on it and it worked. Don't know though if you could bypass that problem by software programming or if you need to do some hardware modification

A question can be asked two ways, so always back your end up with facts.
As for the OP, its a legitimate question, one that needs some baksmali/smali edits to the radio app in order to make it think the head phone is connected.

thankx ''profete162 '' and ''Daneshm90 ''
so any idea from where i can change the values so i can run radio without headset even with noise at least it will work
i am noob in programming
On my old Sony Ericsson K800i, with a patch applied to remove the headset requirement, the radio would work absolutely fine when the headset connector was held in the vicinity of a large metal object (didn't have to be touching), so there is every chance this could work.

need someone to make patch to able the radio in SGS work without headset.
it will work without anntena, signal should be good enough. btw its basic physics, a antenna like the headphone will give u max 3 dBi , which is not that much (Google dipole anntena) compared to the signallevels u normally encounter.
