Hello Ennio,
Sounds like a very interesting project/redesign. Since we are dealing with two distinctly different aspects of this design, one being wireless link to replace the wired cable, the other being power to the sensor device, I recommend we create two distinct E2E threads. Let's keep this one as the wireless link issue, I'll split this to a new thread for the power aspect for the remote device.
Will that work for you?
At your service,
~Leonard
