Hi Sagar, >>> I am very new to bluetooth, so sorry for a novice query. >>> >>> 1: I am using 2.6.37 Linux kernel, can bluez5 stack be used on this or should I use bluez4 ? >>> 2: With bluez5 I am able to scan devices and also see the device on other device but I am not able to pair them >>> Is there some sort of deamon required to pair them ? >> >> BlueZ 5 requires a Bluetooth subsystem with management API support. So at least kernel 3.4 or you have to use Linux backports to at least bring the Bluetooth subsystem to your 2.6.37 kernel. And I have heard of success from people doing that, but I have not personally done that. >> > Probably that would take me more time in back porting. In case of 2.6.37 what version of bluez4 would be best ? the Linux backports project does that automatically. Give it a try. You are not the person with this problem, but it is not something were BlueZ upstream will be of much assistance. I think that our android/README has even some instructions on how to get that started for an Android build. You might be able to adapt that quickly. Just remember that BlueZ 4 is no longer maintained. So with any problems you encounter, you are on your own.
