Captivate, running on Froyo 2.2, rooted unlocked.
I flashed speedmod kernel and after that the bluetooth connection in my car became VERY NOISY. The connection exists and connection is ok, but there is a very strong noise that stops me from using blue tooth.
Any suggestions? Any help?
About phone shows:
Kernel version as 2.6.32.9 hardcore@speedmod-i897-k13c-500hz#28
Baseband version I897UCJI6

I restored back to stock and all works. Flashed speedmod kernel again and again same blue tooth problem.

If you are on stock, or a i987 ROM like Cognition, you lose BT when you flash one of the other kernels. Most of the ROMs and kernels are i9000 based, which have issues (like no BT) when you put them on a captivate ROM.

If you were to flash say, Serendipity, you could flash this kernel with no problems.

I recommend you either load Cognition that includes a tweaked kernel for speed and is Captivate based, or if you want to start kernel swapping around, you need to find a home in an i9000 based ROM.

EDIT- There are some good Rogers based ROMs out there that let you use those kernels as well. Firefly comes to mind.

Thank you very much. I am just starting my experience with Android and of course a lot of mistakes are still ahead. I've been using IPhone for 3 years, but surpizingly I love Captivate.

No surprise... the screen wins people over. :)

If you are at the stage now where you are flashing kernels, I would recommend you peruse the ROM threads on the first page just to see what the first post lists for features. Cognition 4.1 for example is the closest to stock look and feel, and there is a bit in the notes about flashing other kernels to get some of the good stuff on them (BLN, HSUPA, etc) will cause Bluetooth to die. I cannot live without BT, and perhaps you can't either. Apparently there are some that can :).

Firefly is a nice ROM, stable, and lets you use the i9000 kernels that have these other features. Including HSUPA (high speed upload) that currently only the iPhone4 gets to access on ATT. And us of course.

I don't want to turn you off on those kernels or anything, but so long as you are running stock, you will want to leave them alone if you want BT. If you want to get the features they offer, you will need to jump to a full ROM, non-Cognition.

So what car kit do you have? Is it a parrot? Or a built in oem kit? I have been having huge issues and finally found a good combination. I have a Parrot MKi 9200 which is a after market that is connected through my car stereo/speakers.

I have a Canadian Captivate which is rooted, and I use an American odin so I have the AT&T boot screen, Rom is FireFly 2.6 and the Kernel is Speedmod KC13C #28 500hz and I am not using the Rom`s modem but have subsituted the Telus T959JL3 modem and it has almost made my bluetooth issues disappear.

Play around and find the right combination. I have spent a lot of time on xda and found out about all these combinations!!!
