I've successfully compiled the kernel branch of the rtl8723au_bt repo on Raspbian 4.1.12-v7+

The driver seems to be installed, as I can see the bluetooth device. However running hcitool scan returns no devices found. When I instead use a different USB bluetooth dongle, it does find the other device (my phone).

I can see the device with hcitool dev, and I get the following information with hciconfig -a:

hci0: Type: BR/EDR Bus: USB BD Address: 5C:F3:70:1F:9B:23 ACL MTU: 820:8 SCO MTU: 255:16 UP RUNNING PSCAN ISCAN RX bytes:618 acl:0 sco:0 events:37 errors:0 TX bytes:426 acl:0 sco:0 commands:35 errors:0 Features: 0xff 0xff 0xff 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'RTK_BT_4.0' Class: 0x000000 Service Classes: Unspecified Device Class: Miscellaneous, HCI Version: 4.0 (0x6) Revision: 0xb LMP Version: 4.0 (0x6) Subversion: 0x8723 Manufacturer: Realtek Semiconductor Corporation (93)

The dmesg | grep -i bluetooth command returns this:

Running hcidump --raw when scanning shows no other devices:

I'm probably missing something obvious, any help would be much appreciated.

Some other data that may be of use:
