Gadgetbridge cannot find Bangle.js

I too am having difficulty connecting using Gadgetbridge v0.4 from F-droid. I've tried the suggested reset but no joy.

1. I turn BlueTooth off on the phone then back on.
   
2. On the Bangle under GadgetBridge I change "Connected" to "True", it shows a grey icon at the top.
   
3. Start Gadgetbridge on the phone, Add device and then Start Discovery.
   
4. GadgetBridge searches then nothing, and repeated Start Discovery don't appear to scan again, have to kill and restart the app.
   
   

Stumped.
