Touch Pro 2 FM Radio Questions/Answers

[8notime]

This cab has been out for months. It's for GSM TP2's ONLY.

Ok, here is another as a zip file. This MUST be installed in device memory and NOT on the sd card. Also requires a soft reset after installation.

I will also post a link to the xda thread so that if you run into issues you can go there for help.

Have you tested this? Also, have you read that thread? It says it's not for CDMA devices. Go to the last page of the thread where people are still asking if it's for CDMA devices and the answer is no.

I just finished going back and re-reading the thread and you are right. It does not work on CDMA devices. My apologies!

Is this not the Bluetooth chip in our Touch Pro 2's? I thought I read that this was the model of chip in our phones:
The Broadcom BCM2075



Broadcom's BCM2075 Extends Combo Chip Portfolio Delivering Simultaneous Operation of Bluetooth®, GPS and FM Radio in a Single System-on-a-Chip Solution

The highly integrated BCM2075 is a cost effective solution for portable devices, such as mobile handsets, portable media players (PMPs) and personal navigation devices (PNDs), that wish to integrate four key radio technologies (Bluetooth, GPS and FM receive and transmit). In conjunction with its unique InConcert® collaborative co-existence technology, the BCM2075 allows these radios to operate simultaneously, and with minimal interference, providing a compelling user experience. Supported by Broadcom's World Wide Reference Network (WWRN) for accurate indoor and outdoor positioning, the BCM2075 enables advanced LBS, regardless of user location.
The Bluetooth core is architected for high functionality and low power requirements and features the on-board multimedia processing to enable MP3 and other features in more affordable handsets. The chip's FM receiver features superior tuning and station search functions for worldwide frequency bands while the FM transmitter supports programmable output power and a sophisticated algorithm that recommends the best transmit frequency for broadcast to car radios or home FM receivers.
By providing market proven implementations of all these technologies on a single combo device that saves power and size, Broadcom seeks to help drive these adoption rates in next generation handset products.

I can't find anything that says that is the bluetooth chip in the phone. However, I also can't find anything about what chip is actually in the phone.

Also, I was looking for FieldTrial.exe in my windows folder and found the following set of files: FMRadio_PPC_480x800.png, FMRadio_PPC_800x480.png, FmRadioSdk.dll, FMSDKWrapper.dll, FMSkin_480x800.txt, and FMSkin_800x480.txt. Not sure what they are doing in the ROM, but makes me wonder if it is there. I have tried the FM Radio cab and it didn't work, though I was able to tune it but didn't hear anything.

In the Windows folder, you will also find BTFM, which opens the FM radio interface that is built in. (Bluetooth FM)

It would be nice to find out what Bluetooth chip is in there. However, my readings show that Qualcomm started developing the multi system on chip design in 2007. Which includes hybrid radios(both GSM&CDMA), FM, and Bluetooth. All in one chip. Hmm, sounds a little similar so far.

I'm sure someone, somewhere has or will disect one and hopefully spot some detailed markings on the chip. Or maybe, I should just ask HTC what Bluetooth chip and revision is sitting in their devices. That information is what will ultimately lead us to making our FM radio work, or will tell us flat out if there is FM radio ability at all!

Interesting. All of the files you guys listed are not included in the .cab that was posted on XDA, including that .dll. There's a bunch of .bmp files and the .exe, but nothing listed above.

That's because they're not in the .cab, they're already installed in the Windows folder on the TP2. Beware there are 5,000+ files in that folder if you want to look at it on your device (I used Explorer on my computer with the phone connected to it). I looked at the PNG's, and it's simply the skin for the program, but it's definately for the Broadcom chip.

Just did some digging. It looks like we do have FM radio built in. I searched the FCC site for the Verizon model (grantee code: NM8, Product Code: RHOD500). Select the detail link for any of the results, then the Internal Photos link. This will bring up a PDF file with internal photos of the phone, showing off the chips (granted this looks like one of the older, prototype models). The first photo on page 5 shows a closeup of a Broadcom BCM4325 chip next to the Qualcom MSM7600 processor. A quick Google search turns up this page on Broadcom's site about the chip. It describes the chip as: "with integrated IEEE 802.11a/b/g (MAC/Baseband/Radio), Bluetooth 2.1 + enhanced data rate (EDR), and FM receiver." Here's a PDF about the chip: http://www.broadcom.com/collateral/pb/4325-PB00-R.pdf Now we just need someone to do some more digging/programming to get this sucker to work.

Thanks, I was poking around on the FCC site earlier and got side tracked. That was the info I was looking for.
