@Nca78 said in NRF52 Recessed Vibration+Contact sensor for door/window: (and an unpopulated footprint for an accelerometer, too). I wonder whether that unpopulated footprint is where the antenna is?

This project is impressive, I really like it. Pity it is so silent about it. After all this work, are you not willing to finish it?

Ok thank you @Nca78

@nca78 Thanks for the info, Il try it today! Works like charm!
