Noifications "clogged"

Sending simple commands such as print("hello espruino") is working fine (the watch leaves the watch-face app and displays the Bangle.js logo, firmware version, etc and "hello espruino" is printed to the webIDE console).

Ahh - you're pasting into the right-hand side and clicking 'upload', which resets the Bangle and writes just that code.

All you need to do is paste the command into the left-hand side when the clock is running rather than uploading

Also the following GB - call command can be verified with Mario Clock, but notifications doesn't recognize it.

Ahh, sorry. My bad. I think the docs might be wrong looking at it... Try:

GB({"t":"call","cmd":"incoming","name":"­John","number":"+491234"})

This does work - and I just dumped exactly the data I get from Gadgetbridge while accepting a call:

GB({"t":"call","cmd":"incoming","name":"­Home","number":"1234"}) 
// accept call on phone                                                                                
GB({"t":"call","cmd":"start","name":"Hom­e","number":"1234"})    
// hang up
GB({"t":"call","cmd":"end","name":"Home"­,"number":"1234"})
