Hi, I am porting bluez 5.33 to android kitkat 4.4.3.I am using USB based Bluetooth device. I referred instruction in http://git.kernel.org/cgit/bluetooth/bluez.git/tree/android/README and able to build. After botting Android image with USB dongle connected and type "hciconfig hci0 up" on console, It is throwing following error. Can't init device hci0: Unknown error 132 (132) If I Type hciconfig -a . It gives following. hci0: Type: BR/EDR Bus: USB BD Address: 5C:F3:70:6C:5E:FB ACL MTU: 1021:8 SCO MTU: 64:1 DOWN RX bytes:547 acl:0 sco:0 events:27 errors:0 TX bytes:384 acl:0 sco:0 commands:27 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT But If I unplug and plug USB dongle, and then try same command (hciconfig hci0 up), It works. Even "hcitool scan" command also working after that. Why 1st time not working when USB dongle is connected? Also when I check Bluez debug log in logcat. I am getting one error log when USB dongle connected during boot. E/bluetoothd( 841): Failed to set mode: Blocked through rfkill (0x12). Please let me know If I missed any settings Thanks in advance, -- 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
