So, Im interested in using some more power efficient modules for sensor telemetry and the NRF24L01 units seem quite suited.
I see theres some good libraries floating around (including tmr's which seem significant) but before I get sucked massively into documentation I had a couple of questions, which can hopefully pick the brains of others with more experience.
Is there a mechanism to manage access control (eg only 'authorised' sensors can connect to a master node).
Is there a chip level unique ID for the NRF modules.
Do the libraries implement frequency hopping?
