The big picture: I will have a microbit that is baseSta and one that is Sta1, or more.
The baseSta will be the main controller, more or less, it will request different things from the other units, and deal with that information, via the radio.
Sta1/x, I will start with one unit, this will mainly do a specific job, get sensor data as requested by the baseSta. Will use the radio for data transmission. I will probably use a job distribution method for reducing the stress on one unit.
The job distribution might be something like, one Sta could be running part of the softRTC as a task and another Sta could be running another part of the softRTC, so on so forth.
