Can no longer connect to my bangle.js 2

Hi @itsjpb,

Sorry to hear that - but if you can connect via Gadgetbridge and it's showing the bluetooth symbol as blue, I'd be pretty sure you have something like Programmable set to Off in the Bangle.

Maybe you could check Settings -> Bluetooth -> Programmable is set to On and then exit back to the clock. You could also try Settings->Bluetooth->Make Connectable as Christine suggested above
