I was doing some research on the BCM4329 chip that our Droid Incredibles have. It looks like this chip supports 802.11 a/b/g/n on both the 2.5Ghz and 5Ghz bands and comes with both an FM receiver and transmitter.
I know we already have some nice guides that can enable the wireless N, but do they have the ability to use the 5Ghz frequency yet?
We already have the ability to use the FM receiver/tuner, but can we enable/use the FM transmitter? I for one always use my DI in my car to stream music, and a built in FM transmitter would be great!
Here is the specsheet for the BCM4329: http://pdf.eccn.com/pdfs/Datasheets/Broadcom/BCM4329.pdf

I don't really care about the frequencies (though it'd still be nice) but the FM Transmitter would be MONEY! Unfortunately, as far as I can remember All Droid members were working on it before it went down the $h!tter, and they were saying that w/o any built in Android support, or love from the manufacturers it will be a daunting task, since there are not even any drivers for that, that we know of that have been developed.
FM TX will really depend on the hardware. What we need is a true datasheet, not a product overview. If the chip is a true FM-to-antenna solution then that might make things a lot easier, but if the device needs external filtering/matching and other RF circuitry, then a viable solution will really depend on the layout of the incredible hardware and if there was any foresight into having FM TX as an option to begin with.
Unfortunately I think HTC probably did not include any external circuitry for this feature since it adds BOM cost for them, but again if the chip just needs an antenna then maybe it will work like the FM receiver which uses the headphone jack as an antenna.
Like I said, a real datasheet with hardware/register overview is what we need.

-sorry, that's just the product brief.
no problem...I tried looking for this when the specs for the DI were first released and it was rumored to have the BCM chip, but didn't have much luck. Sometimes you get luck with google and find a Russian or Chinese site with the leaked datasheet...no such luck so far though.
I found this:
http://www.broadcom.com/collateral/wp/4325-WP100-R.pdf
But I don't think it is what we need.
I hate to noob it for you gentlemen, but what is a datasheet; or better yet, what does it look like? (So i know what to look for) Is there any specific info/section you need in said datasheet? Just need enough to locate what you need, not any real understanding of chips and/or software.
Thank you all.

I think we should somehow merge these two threads as they both are trying to achieve the same thing.
so some are going off on the depend and saying the fm means freq mod .
NOPES
Broadcom clearly states its a "FM radio receiver and transmitter."
SO YES IT DOES HAVE THE CAPABILITY TO TRANSMIT AUDIO OVER FM
where i got this from .
http://www.broadcom.com/products/Bluetooth/Bluetooth-RF-Silicon-and-Software-Solutions/BCM4329
as we know software wise the evo has no fm Transmiter software installed and like we know Wifi N was in it and turned off till now.
so sometime soon we hope someone will come out with an APK to use the fm transmiter. (to stream our media to fm radios for car or house use.).
actully if you look at there app guide they have a unit without the FM TX.

Has someone access to the engineering documents from Broadcomm? We just have to make a short look on the reference design and check, whether the TX part needs some external circurity. If so, we need to check whether the phone has this implemented. If not, then even a working driver would not help to activate this feature.
So my point is: has someone access to the documentation of the BCM4329???
PM me everyrtime =)!
Cheers!
Bad News! Phone needs additional components to make the Tx part work!
Too bad. Would have been nice.
I know the msg from Qualcomm said 'additional components', but the headset cable is the addition to make the RX work.. wonder what else would be necessary for the TX function.. One of my old lg phones had FM TX on it, best feature of the phone. I love hardware modding, wonder what else would be needed?
all that tells me is extra components are required on the board to rx or tx. but they dont say if they are the same or different.
From what i can tell with my Tech Background and what i do know about the chip from the public data sheets aswell as what i posted on the other thread.
I think all we need is the software to pump the audio to the fm part of the chip its uart so its bidirectional for all data.
to give you a wee bit of how i would have a clue about this.
super short version grew up around Pro Audio Test and measurement and internals of electronics Building designing from like 8) aswell my heydays with my IC735 (modded) (into all tech areas)
but going back to the fm.
if it can receive fm then it can transmit it. bottom line.
the only thing we need is the software.
so heres why.
the data i have (very clearly says that the fm part of the chip has its own single antenna for rx or tx so no switchs etc needed. (the chip boasts every thing that is in it has all supporting parts inside IE Amplifyers (wifi BT use a external switch but fm clearly shows it doesnt)
so going back to that its an antenna connected to the TXR (rx,tx) fm part of the chip. and has a UART IO so it has biderectional.
if it can recieve and tune the freq to RX then it can tune and pump to fm TX
basicly chip goes.
AUDIO (Uart) In out ---- RX,TX Chip and antenna
all there allready ONly thing missing is software to put the audio in not pull from it.
Guys. Electronics now days (He!! back in the day) its simple just take peice by peice not evertying has to be so complex it cant be..
sorry typing from phone so no spell check EVO turned off to increase speed.
OH going back if you look at the public docs. you will clearly see the wif and bt have external switchs for the antennas.
and the FM shows one antenna and no switches for rx or tx. Take a look comon sense tells you htc wont admit it can do tx right now.. we would demand an APP.
they need to sell us something later. but use todays chip.
I've seen the datasheet. Of course I think, there is no need for a second antenna. BUT maybe it could be possible, that there is some LP or HP needed on some pins or any other component which would have increased the BOM about 0.1 cent. Not to mention the additional area needed on the board of the phone...
So as long as I don't see any detailed spec sheet of the BCM4329 which clearly points out that everything is on board, I will not try to develop a software for it (which I am willing to)!
Bottom line.
Does anyone have any resources to get the required datasheet for the BCM4329?
I assume it is too complex to reverse engineer. (Am I wrong?)
Broadcom Open sources their drivers
Broadcom has announced they are going to release the source code for their drivers, the BCM4329 is not yet listed, but maybe it will be soon?

Think about that tho,
How much power do you possibly need to transmit a low power signal from less than 2 feet away. Wifi transmitting (upload) probably takes up more power.
This would be an extremely nifty feature, though I would reckon it would eat your battery pretty hard, not to mention the heat output.

Spoke with an engineer at Qualcomm who makes most of the 911 GPS devices for the phones. They did say that there is a way to access it and use it with consumer GPS programs. However they said it was a secret and they couldn't say how. They did however say that each provider disables it in their own way. At least I know it's possible now.

What do you want to tell us? That the Wizard has a built in GPS? Did you read the Spec of TI's OMAP CPU and seen that there is a GPS block?
I suppose that the developers have omit the antenna. Without antenna no GPS signal and therefore nothing to compute.
"I want to believe" says Agent Mulders Poster in his room in the FBI HQ...
I don't believe in this "emergency GPS" in all Handys. It's like beeing catched by Aliens...
A Phone can be located over the GSM network by looking at the radio station it's connected to.
The e911 gps feature is real. It provides more accurate locations for cellphone calls than triangulation so I read. Besides why would an engineer at Qualcomm lie? We talked in as much detail as we could.

No I haven't read that, could you post a link? I am new to the MDA.
in the service manual i can't see anything that looks like a GPS chip or something, and btw, i think it would cost to much battery power!
I have absolutely no idea about the picture I am going to post a link to, but have a look.
Look at the upper right corner next to the IRDA bit.
Could there be truth to this thread???
http://msmobiles.com/f/viewtopic.php?t=9056
lutz,
the e911 gps chip isn't "always-on"
it on only activated with a user dials 911....there has been a porven hack that enables this by a user re-programming their phone to think that 922 is 911 and thereby dialing 911 would enable the GPS coordinants displayng htem on the phone.
*edit*
A quick google search shows this:
http://www.cellphonehacks.com/viewtopic.php?t=25480&postdays=0&postorder=asc&start=30
Also just in case this site smashes that site I'm attaching the PDF's to the forums first 3 pages (at the time that was all the pages)
ok there maybe is a AGPS like feature in the second thread mentioned. but in the wizard there is not such thing. the picture in the first thread is only a architecture overview.

Qualcomm makes GPS for CDMA and EVDO handhelds, NOT GSM phones. The GSM network uses triangulation for positioning. The engineer was full of donkey doodoo.
There IS NO GPS hardware in the Wizard.
i did a registry tweak to my mda that enables settings for gps in the connection settings. so i know there is gps software on the wizard. why would tmobile have that on there if there isnt any gps hardware??
Could you say what the registry name / value is?
TBH, I know I posted the block diagram link, but as I don't understand those things.................
I can't see the wizard having a gps part as surely with the increase in
sat-nav consumers, it would have been an extremely positive selling point.
It's like selling an old jacket on e-bay and not mentioning the stash of cash in the pockets!! :wink:
the GPS setting in the connections menu is for controlling an external (bluetooth) GPS. This feature is new and on every WM5 Device ; )
This diagram only shows what is capable with the OMP850 processor, this wil not say that it’s in our Wizzard.
If you look into the service manual posted in another thread you will see that there is no internal antenna for a GPS receiver.
So the GPS hardware isn’t onboard the Wizzard.
If you look closer to the diagram you can even see more functions of the Omap850.
WLAN A/B/G
Serial port
U-wire port for a secondary display
Except for WLAN B/G the rest isn’t in our Wizzard.

I have never seen this, could you explain some more please?
And looking at that picture ends me back to another thread I startedon here regarding whether or not the miniSD slot is SDIO enabled.
take a look here: http://forum.xda-developers.com/viewtopic.php?p=260882
On my ipaq hx2110 the menu was default on, but on the wizard you must enable it.
Hi Jerry,
The picture you see is what is capable with the chip made by Texas Instruments.
But the designers of the HTC Wizzard haven’t used all the properties of the OMPA850 processor so there are a lot of extra’s who aren’t used.
This is also the case with the GPS receiver witch can be used on board of the Wizzard but it isn’t by design.
The Chip can handle SDIO but if the designer disables it software wise or use on interface connected to the Chip that isn’t SDIO capable then it isn’t there.
I can give you an example.
Years ago I had a VCR but I couldn’t buy the one I would have so I bought a cheaper one in the same series.
Mechanical it was the same but there where a few switches let then the one I had in mind.
After opening the cover there where on the PCB board holes where there used to be switches for the more expensive one.
After some DIY I discovered that only the switch was missing but not the software in the VCR itself.
So I had the more expensive one for less money.

With such complexities of being a world phone and pocket pc and all... there's no way to use these as a standard FM radio? Are there hacks available for this or is it impossible given the Hermes/TyTN hardware?
I'd guess it would need some tuner hardware.
I know its not what you want, but Resco Radio has a bunch of internet stations to listen too. Maybe you could look if the stations you are interested in have live streaming and use that link in Resco Radio? Not exactly sure but it may work...

Sorry to rain on your parade but the documentation I've been able to find about the Atom says that it does contain FM radio hardware.
It _has_ to. It wouldn't work otherwise. Don't get me wrong, I wish I could turn my hermes into a HTC Kaiser with added FM Radio just by installing some bit of software and holding down certain keys while resetting it but the real world doesn't work that way. There's a reason why 'transformers' is fiction and not fact and there's a reason why you can't actually send your children to Hogwarts to learn how to be magicians.

i dunno about that a transformer blew up in NY yesterday LMAO
I stand corrected about the XDA atom specs.... The page I initially saw with the atom's specs, didnt mention it... I then found another one saying it has FM Radio capabilities... Oh well.....
I don't know much about radios and frequencies (clearly). I just figured that if the phone is able to pick up these GSM/Edge/UTMS... etc.. frequencies/spectrums then perhaps there's an off chance it could pick up an FM frequency which I'd imagine is pretty standard. Ah well.
The TyTn can pick up close range radio signals for example when you use bluetooth. However it has no tuner to select broadcast radio frequencies. In addition it has no aerial suitable for effectively picking up radio stations. Many phones that have FM radio built in, only work when you plug in the headphones. This is because the headphone cable acts as the aerial. The TyTn does not have it's circuitry set up to use the headphone cable as an aerial.
So even if you could somehow use software to tune signals using the bluetooth aerial, this aerial is not nearly big enough to pick up FM radio stations. So, no suitable software and inadequate hardware to make it work. Streaming radio is the only option.
Mike
I was wondering if it is possible to use the FM chip in the phone and use it as an FM transmitter (like the n97)
I'm interested in hearing your thoughts.
Basically no.
For a start, you'd need a chipset capable of transmitting via FM as well as receiving. Just because you can do one, it doesn't mean you can do the other.
Even if the chipset is capable, for it then to work, it'd need to have the necessary drivers installed, which is maybe doable.
It'd also then need an antenna attached to the transmission pin-out on the chipset, which is extremely unlikely to be in place.
So technically it might be possible but in reality it's not - unless SE just happen to have built a fully-functional FM transmitter into the Arc and just forgotten to activate it...
I think we have a chance to activate the FM transmitter in our phones..
At least we should give a shot?
The BCM4329 has FM Tx & Rx abilities. The Rx part is not used, but maybe we can use the Tx part?
Unfortunately, google doesn't help a lot.
I know that our galaxy S i9000 uses a Si4709 chip for the FM reception, so that's not good for the transmit part.
does somebody have any useful info about this?
i would definitely do everything i could to make this work. this should be the biggest hit feature...
this is a problem for me too.... amy someone helps us...
That was discussed a long time ago without any progress.
Apparently we can't use the FM transmitter if there is one inside SGS
why can't we? what does stops the devs?

First it's not easy without manufacturer's cooperation to have access to the chips and phone documentation, so how to create the drivers drivers ...
Secondly don't even know if physically it could work (for example the transmitter would need a antenna...).
i think the problem was no connection of some pins of whatever - use search option
the antenna issue i think it's not the most problem, I think the not connected pins is more complicated if that is true.
FM transmitter could be nice, but like it seems Samsung probably didn't connect the relevant pins for transmitting audio.
I know the package is the Azurewave AW-NH665 but there's no data sheet published for that. I'm hoping it's got at least a BCM4330 in it. Also hoping for BlueTooth 3.0.
someone who has one check your system/etc/nvram_nh665.txt
it should have info on the wifi chip.
Thanks.

Well, I can tell from the kernel it uses BCM4330 chipset. That should mean b/g/n, Bluetooth 4.0+HS, and FM...

Nice, just checked out your radio app. Would be very cool to get that working on the N7. Interestingly I noticed that although that firmware is present, the kernel is actually configured to use:
/system/vendor/firmware/fw_bcmdhd.bin
Not sure exactly what the implications are of that yet.
There are 3 identical files, size 209,175 bytes, and they are for the WiFi core on the chip. Bluetooth and FM share a seperate core.
fw_bcmdhd_apsta.bin
fw_bcmdhd.bin
fw_bcmdhd_p2p.bin
brcm_patchram_plus is a Broadcom proprietary replacement for hciattach and it loads the bcm4330.hcd file. I'm 100% sure because my FM app can do the same as brcm_patchram_plus.
The top of the HCD file contains: "AZW Module665 BCM4330B1 37.4 MHz Class 1.5 ExtLNA"

There is not a single, easily available non-obscure Android tablet over 5" which supports FM. So if possible, even if it requires some hardware mods, the popularity of Nexus 7 will make it compelling for the combination of Android tablet and FM.
Further, FM transmit on Android is virtually unheard of. With access to the transmit antenna pins, this might be possible. There are LOTS of people who don't care about receive, but want transmit to their car stereo.
I expect to see a good number of hardware hackers looking to use the Nexus 7 as a built-in car/entertainment device.
