Aqara U200 BT failure

Aqara U200 - Bluetooth problems .

Well today just like that the U200 stopped responding and unlock and lock the door.
I’ve tried to get into the app on my iPhone and found out it was disconnected and I wasn’t able to connect it back , after a lot of games with the lock I’ve decided to reset it and once I’ve connected it back and arrived to the calibration stage it got disconnected again and refused to connect back - I’ve done it 3 times and every time in the same screen when I press the calibration button I hear one bit and nothing.
Is there any fix for that or I can move on with other lock?

So this kind of connection problems are new to me … I just know that inside is a small antenna connected and I knew a case where the antenna cable get of the connector inside :grimacing:
So if you run already out warranty, I would open it and check the connection- if it’s still on warranty I would contact the support :v:t3:
