dwm1001 BLE wakeup stop working

Hi there,

I run into an issue on dwm1001 module, the BLE wakeup button stop working, I found the voltage on BLE wakeup pin which was high before now becomes low and stay low. I’ve tried to reset or re-power the module but couldn’t fix it. don’t know why?
when this happened I lost BLE communication between dwm1001 module and DRTLS manger app but still can get position data via uart API.

The only way I found to recover from this is to erase and reprogram the module with the factory default firmware image. this is unacceptable in field.

Does anyone know why and how to recover from it without reprogram the module?

Thanks in advance
