Moode 4.3: Can Pair but Connect Fails w/ `connect error: Permission denied (13)'
#1
I am running Moode 4.3 and have rebuilt it twice from scratch and both with the same result: 
I can Pair a bluetooth device (UE Boom 2) but I get the following in syslog when I try to connect. Using `tail -f` the mpd.log registers nothing. It was working and then I mucked around in the BT config

Code:
Oct 15 06:30:11 moode systemd[1]: Stopping Music Player Daemon...
Oct 15 06:30:11 moode systemd[1]: Stopped Music Player Daemon.
Oct 15 06:30:11 moode systemd[1]: Started Music Player Daemon.

Oct 15 06:30:19 moode bluetoothd[1113]: connect error: Permission denied (13)
I am not sure where to look for a hint as to what the problem might be. 
Any hint would be appreciated.

The symptom "It was working and then I mucked around in the BT config" suggests that reverting the changes should fix the issue.

Hi Tim,

I reset the system by d/l the Moode 4.3 ISO and trying to setup the UE speaker. I turned on Bluetooth, Paired the speaker and got the same error above when trying to connect.
The Speaker can connect and play from my android tablet and phone. I can also pair to the player and play music from these two device to the pi.

Stumped!

FWIW I have included below the `systemcfg status' output for bluealsa and bluetooth ad well as my system info':

Hi,

Very odd. I have a small Anker SoundCore speaker and no issues.

When my speaker is turned on it automatically connects to the Pi. Maybe your speaker is automatically connecting to your phone or tablet and then appears as "busy" when you try to connect from moOde ??

I had a similar experience on an earlier version which was solved by disabling Sox re-sampling.

Hi Tim,

FWIW being a year down the track, I eventually resolved the BT connect problem to UE speaker: 

I had changed the default name of the speaker using an app provided by UE which was fine. I then got my problem pairing with MoOde. I gave up. Then, for no particular reason, I decided to revert to the default name. 
The next time I tried pairing it worked.
