bluetooth keyboard repeatedly disconnecting

After having problems with the BT connection constantly dropping out, I resolved to remove the the device and try again to pair and connect. At first I could get it to pair again, but not connect

[bluetooth]# connect 7C:ED:8D:67:D4:2E

I tried one more time to follow the Arch Wiki on Bluetooth before posting and this is what happened:

Now it's disconnected again!
When I touch keys on the BT keyboard, the bluetooth symbol appears momentarily in my Gnome system tray
