Hey there,
For some reason, `scan on` does not return any devices in my system. I follow the instructions in the wiki, power on, agent on and then scan on, but no devices are returned.
I doubt that `scan on` actually scans at all. Something is funky, and I'm not sure how to debug it.
λ bluetoothctl
Agent registered
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent is already registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
[CHG] Controller A4:5E:60:EA:BE:4A Discovering: yes
[bluetooth]# devices
[bluetooth]#
I tried connecting directly to the device by passing the mac:
λ bluetoothctl connect C8:08:54:7A:D0:1A
Device C8:08:54:7A:D0:1A not available
lsmod:
λ lsmod | grep blue
bluetooth 675840 37 btrtl,btintel,btbcm,bnep,btusb,rfcomm
ecdh_generic 16384 2 bluetooth
rfkill 28672 7 bluetooth,cfg80211
crc16 16384 2 bluetooth,ext4
systemctl status:
λ sudo systemctl status bluetooth

The weird thing is; this used to work as expected. I had pairing issues but scan was working fine. All of a sudden, now scan also does not work and I can't see any error indicating the problem.
Any ideas ?
