How to get RSSI value, send to sensor, sensor receive package, repackage it? Hi
I have a project:
1. a client sensor broadcast package
2. there are 5 rooms, each room has 2 sensors
3. the sensors receive package, embed the sensor Id
4. send the new package to server through multihop
5. server get the new package through Delta.
How should I change the following nc code to do it?
