Custom bluetooth service on bangle.js

Oops - sorry forgot to refresh before replying.

I assumed the code would be pretty cross compatible.

Yes, it'll be identical. I'm not sure Robin's post is too helpful

I have saved the watch app into the device storage, I run the app on the watch with no devices connected

That sounds perfect then. And it's displaying the "Waiting.." message? I guess you could add NRF.disconnect() command after that to force a disconnect.

By disconnect do you mean completely unpair and then repair?

You shouldn't need to - however if you are paired with a device then sometimes the computer will try and hang onto the connection even when no app is connected.

Also, it depends on your device but I believe iPhones especially cache the Bluetooth services - so you need to turn Bluetooth off and on again to get them to load the new services
