Spirit FM radio App and Cyanogenmod 7.2 - Optimus One, P500, V General

I had a couple of questions about using Spirit FM Radio app on CM 7.2. And I would like to know in detail about it.
Firstly, When I ran the Spirit app on CM 7.2 i noticed that it doesn't switch on the Bluetooth. Does that mean that it uses the internal Broad com FM chip instead of Bluetooth to receive FM transmissions just like in the LG stock FM radio app?
Will the Spirit FM app still run properly if I UN-install the CM 7.2 Stock FM app? Or does it need the CM 7.2 Stock FM app to run properly?
In the setting of the app, within audio, I saw various options like cyanogen Mod, LG, lge-msm7x27,etc. Even tough i didn't see any difference in quality while going through different options. Which would be the ideal option for us and What do these options do?

CM9 hasn't got a radio am I right? (Btw I'm new to the forum I couldn't find a topic to write this I'm sorry

What phone are you using?

When Bluetooth is enabled FM is enabled too because they locate at the same chip. It's the easiest way to enable FM and so is CM radio doing. Spirit FM (and stock LG) does it little bit harder by only enabling FM thus saving some starting time and battery (battery part is not a 100% fact though, only my own speculation).
You can remove CM radio, it is not needed.
Recommended method by author in Spirit is CyanogenMod. I don't know exactly what are the differences between different methods but stick with CyanogenMod.

Spirit FM does use Bluetooth, only the icons aren't changed that's all.

I might be wrong but if Bluetooth is turned on i see no indication, not only in status bar, settings, no device discovers it (visible), i think i need an app to check the components...
Will check back whit the answer
Edit: It dose use bluetooth

How did u finally come to that conclusion that it does use Bluetooth? And if it does... Does that mean that there is no big difference in the way Spirit, Cyanogen mod and LG FM radio app works?

Yes you can remove the CM FM app.
On CM7, the default CyanogenMod audio method is generally best. It's the same method the CM7 FM app uses, so it's the most likely to work well, especially when dealing with things like phone calls coming in when FM is on.
If a CM ROM for any phone has a CM FM app, this method should work, but unfortunately that's not yet the case with CM9 ROMs. so low level methods are needed for now on CM9, and there are often issues, and many CM9 ROMs just don't support FM audio routing yet, or I haven't figured them out.
Re: Bluetooth: my app has many ways to access FM chips.
- The first method I supported was via Bluetooth (the HCI API), like the CM FM app. Like it, my app can run commands using the command line hcitool utility, and this is nice because my app can run without root/SU. But it's not too efficient, especially when using RDS where lots of data gets transferred.
- For better efficiency, with root, my app supports direct access to the HCI sockets, through a daemon, because apps don't have the privilege otherwise.
- But because many people were running stock or stock derived ROMs using the Broadcom proprietary BT stack, and I could find no way to send HCI commands with it, I created a "UART mode" that communicates directly with the Bluetooth/FM UART. The wireless part of Bluetooth is not switched on, which saves power. But this mode requires root (unless /dev/ttyHS0 or whatever is accessible from an app), and only works if BT is off.
- A new access method is available now on stock and stock derived ROMs that run the proprietary Broadcom BT stack and that supports the stock LG FM app. This can work on stock, unrooted devices. In this mode the characteristics of the stock FM stack are unavoidable, both positive and negative.
The Broadcom proprietary BT stack has a special mode where Bluetooth is considered off, but FM is on. This enables the Bluetooth HCI "UART" to provide a path to control the FM part of the chip.
- There are different device driver access methods used for dedicated FM chips not contained in a BT/FM combo chip, but those don't apply to the P500.

OK for SGA?
Can I use this FM radio app for my Samsung Galaxy Ace? I have Ice Cream Sunday ROM installed.

Off-topic, and you should ask on my thread anyway, or check post 2 of my thread. Please don't respond here.
Canned response now:
The Simpsons taught me that among Hemingway's words of wisdom was:
“The shortest answer is doing the thing.”
IE, why don't you just try it ? It's free and only takes a minute or two I think.
There's even an intro that can be read and will give some useful information on configuration.
Then if you have trouble, you can come back, report it, and hope for an answer.

Thank you for clearing it to me. But I don't know... something weird happened to me. I was using Spirit FM radio app whole day yesterday but the Blue-tooth icon never showed up. But today when tried the app again It has been showing the Blue-tooth icon. I don't get it. What changed? I tried re-booting and everything. Still the same.
