I have the same symptoms. Am trying to connect a BQ M10 with OTA-13 to a Microsoft Wireless Display Adapter and having only timeouts:

aethercastctl> scan
[CHG] Manager Scanning changed: true
Device 9a:5f:d3:ba:f6:f2 MSDisplayAdapter_F2 added
aethercastctl> connect 9a:5f:d3:ba:f6:f2

[CHG] Manager Scanning changed: false
[CHG] Manager State changed: configuration
Failed to connect with device: Timeout was reached
[CHG] Manager State changed: disconnected
[CHG] Manager State changed: idle

Looking at /var/log/syslog, I get the impression that it is a file permisson problem (lease file can't be created) or that apparmor is blocking the DHCP process:

After setting /run/aethercast/ to world-writable for testing:
 sudo chmod 777 /run/aethercast/

I got to a new error message:

Oct 20 15:48:47 ubuntu-phablet dhcpd: Can't create new lease file: Permission de
nied
Oct 20 15:48:47 ubuntu-phablet kernel: [116007.269469] (1)[22043:dhcpd]type=1400

" pid=22043 comm="dhcpd" requested_mask="c" denied_mask="c" fsuid=0 ouid=0

I believe this points to a problem with directory rights and/or AppArmor configuration.

Hope this helps..
