I'm currently trying to set up communication between two NRF 24l01 transceivers. In my setup, I have two radios operating in sleep mode for the majority of the time, every once in a while I would want them to wake up and check if there's another radio within reach, then set up communication. Ideally the NRFs would wake up, send out a signal (a ping) and wait to hear something back, if they don't, they go back to sleep.
However, I can't figure out how I would get one to transmit while the other is receiving at the same time. If you're wondering, I'm going for this implementation so that I could ideally scale it to more than just these two modules in the future (any rf radio can speak with another one).
Does anyone know of a similar implementation from before? Or do you have any recommendations?
