[How To] Using the Satechi Bluetooth remote with moOde 5.4+

[Haven't looked at your Pairing Agent code, but at first blush it doesn't seem to matter in the following if the Agent is on or off.]

In a nutshell: scan, pair, enter PIN, connect, trust.

Code:

pi@moode54b23a:~ $ sudo bluetoothctl
Agent registered
[bluetooth]# scan on

[Bluetooth Media Control & Camera Shutter Click]#                               ## NOTE 3

Notes

1. Satechi doesn't show up until I click its own scan button
   
2. If I entered the wrong PIN (fat fingers!) then CHG reports "connected: off" and bluetoothctl offers a new PIN
   
3. from here on, Connected sometimes transitions to "no". I think it relates to the Satechi going to sleep (or being off but doesn't seem to happen synchronously with turning off the Satechi). In any case, the connection is reestablished when the Satechi is waked up with a button press or is turned back on.
   

After the above actions, moOde's Bluez Config shows "Bluetooth Media Control & Camera Shutter Click" in the list of paired devices and asks if I want to connect or remove, even when bluetoothctl says its connected.
