Bug Description
Each time I boot up, bluetooth doesn't work until I run "hciconfig hci0 up". Then it seems fine until the next reboot. This may be related to bug #1244764.
Before I run hciconfig hci0 up:
- rfkill indicates that the bluetooth device is *not* blocked.
$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
- The gnome control center bluetooth module thinks that bluetooth is enabled, but scanning does not work. These messages appear in syslog when I click + to add a device:
bluetoothd[
bluetoothd[
Then I run:
$ sudo hciconfig hci0 up
At that point in syslog:
bluetoothd[
Then when I try to scan for bluetooth devices it works, with this in syslog:
bluetoothd[
I can just add an upstart service that runs hciconfig hci0 up at every boot, but that shouldn't be necessary if everything works correctly.
