Hi Murat,

However, when I try to read a feature report from this device, the Bluetooth service crashes. The bluetooth service log and my source code are below.

4294967295 is the same as (uint32_t) -1 so seems like there might be a
missing error check somewhere. Could you please try to get the full
bluetoothd backtrace by running it through gdb or valgrind? If possible
do this with the latest git version.
