Since i've updated to Firmware v21 my Bluetooth-Connection started dropping 30 times a day and now it cannot connect at all. I cannot see it neither in bt-settings of my phone (android), nor in gadgetbridge (pairing), not in nrf-toolbox (and its dfu-part) and even not on my laptop pc (bangle-app-loader and online-ide). Already tried a clean boot and a factory reset without any success.

Do I have more options apart from ordering a new one? Is there a possiblity to diagnose it further via the rx/tx over the charging-cable (don't know if they still work because one has almost disappeared due to corrosion)?

Thanks for the hint. Thats exactly the problem. I put a clamp to compress the watch on the top-right corner and it connects now. Anyone has experience with opening it? Is there a manual howto do it without breaking the case?

Sorry to hear that - it's probably better to respond on the post linked above that you just posted on though: https://forum.espruino.com/conversations/394518/#17309516
