When I do a rfkill block bluetooth, the internal bluetooth device disappears from the list. A external USB bluetooth adapter on the system does not disappear. here are the observations : A. rfkill list shows 2 bluetooth adapters. hci0 is the internal one and hci1 is a external bluetooth adapter. barsode@tatooine:~$ rfkill list 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: tpacpi_bluetooth_sw: Bluetooth Soft blocked: no Hard blocked: no 5: hci1: Bluetooth Soft blocked: no Hard blocked: no 8: hci0: Bluetooth Soft blocked: no Hard blocked: no B. then I do rfkill block bluetooth. Now rfkill list shows only 1 bluetooth device. barsode@tatooine:~$ rfkill block bluetooth barsode@tatooine:~$ rfkill list 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: tpacpi_bluetooth_sw: Bluetooth Soft blocked: yes Hard blocked: no 5: hci1: Bluetooth Soft blocked: yes Hard blocked: no C. hciconfig -a shows only hci1. barsode@tatooine:~$ hciconfig -a hci1: Type: USB BD Address: 00:1A:9F:92:B3:FC ACL MTU: 1021:7 SCO MTU: 64:1 DOWN RX bytes:3986 acl:0 sco:0 events:128 errors:0 TX bytes:3909 acl:0 sco:0 commands:128 errors:0 Features: 0xff 0xff 0x8f 0xfe 0x9b 0xff 0x79 0x83 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT This is a problem for offline mode in connman (which would do "rfkill block bluetooth" or "rfkill block all") & the internal bluetooth adapter would disappear, which is not expected. Is this common on laptops or its just thinkpads? I tested this on a HP laptop which does not remove the internal device when i do rfkill block bluetooth. the only way to get around the problem seems to be rfkilling each device individually or am I missing some info here. Thanks, Alok. _______________________________________________ connman mailing list connman@connman.net http://lists.connman.net/listinfo/connman
