I am working on a project for which I need to attach the four raspberry pi boards on the ceiling of the room (one at each corner).
The script that will run constantly scans the BD Address and the RSSI values of the nearest ble devices.
Now, due to the unavailability of power sockets I need some power solutions for my boards. I have 3.7 volt 560 mAH lithium batteries. Is it possible to use these in any way? or some other cheap and best solution (the project is with a company and not much budget is allotted for the same).
Thanks in advance Aditya
