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 16550A [ 5.629222] Bluetooth: Core ver 2.21 [ 5.629287] NET: Registered protocol family 31 [ 5.629291] Bluetooth: HCI device and connection manager initialized [ 5.629299] Bluetooth: HCI socket layer initialized [ 5.629305] Bluetooth: L2CAP socket layer initialized [ 5.629318] Bluetooth: SCO socket layer initialized [ 5.643749] Bluetooth: HCI UART driver ver 2.3 [ 5.643757] Bluetooth: HCI UART protocol H4 registered [ 5.643760] Bluetooth: HCI UART protocol BCSP registered [ 5.643763] Bluetooth: HCI UART protocol LL registered [ 5.643765] Bluetooth: HCI UART protocol ATH3K registered [ 5.643768] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 5.643853] Bluetooth: HCI UART protocol Intel registered [ 5.657970] hci_bcm BCM2E39:00: BCM irq: 192 [ 5.658046] Bluetooth: BCM2E39:00: Asus T100TA: Overwriting IRQ polarity to active low [ 5.658051] hci_bcm BCM2E39:00: BCM2E39:00 device registered.

Bluetooth BCM chipset is no more managed by rfkill and hciattach. You should use btattach to register it (BlueZ >= 5.31): btattach --bredr /dev/ttyS4 -P bcm then (you should change the device address): btmgmt public-addr "43:24:b3:01:02:03" Hope this helps -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
