About addressing several drones

Post by abrahamvee » Sun Oct 20, 2019 9:11 pm

Is the use of one radio channel and individual addresses for each crazyflie the implementation of the data pipeline capabilities of the wireless chip? Or is it time division multiplexing?

We use address in order to communicate with multiple Crazyflie. Different channels can also be used but is not to be trusted since we have seen cross-talk between channels. Though using different channel is used to communicate with different Crazyflie simultaneously.

When communicating with multiple Crazyflie using one Crazyradio, the communication with the Crazyflies happens one after each-other. When adding more radio, each radio is setup to a different channel to allow simultaneous communication.

I hope I answered your question.
