Hi,
I met this problem when using Moto headset H710 with BlueZ. Could anyone guide me to fix this issue?
Any hint is much appreciated.
Thanks,
Leo

Use Motorola H710 to connect BlueZ, it will make authority verification 2 times. The reason of failure at the first time is caused by this swapper Not tainted error. This error will report as following error in application level:
