Hello
since kernel 4.2.3 the bluetooth on ASUS t100TA stopped working
can no longer initialize it using hciattach /dev/ttyS4 bcm43xx command it
always times out it also registers different in dmesg
80860F0A:00: ttyS4 at MMIO 0x9094d000 (irq = 191, base_baud = 2764800) is a

not sure if this is a bug in the kernel driver or if something was changed
BlueZ and not updated in the bcm driver
also it no longer registers with rfkill which i think was changed
let me know if you need any more information
thanks
