Ad hoc mod possible for the Crazyflie Nano Quadcopter radio system

[thibfer]

Hello everyone,

I would like to know if the Crazyflie Nano Quadcopter's radio system has a ad-hoc mod.

In fact, I would try to establish a communication between two Quadcopters or more. So, this mod will be very helpful for me.

Thanks by advance for you answers

There is no software for it but it is possible with the Crazyflie hardware.

This would need to be added to the crazyflie2-nrf-firmware project.

Do you have a use-case for this functionality?

In principle this should be possible. There are libraries such as RadioHead http://www.airspayce.com/mikem/arduino/ ... index.html, which can do (among other things) mesh networking. RadioHead works with the NRF24/51 family chips. However it's made for Arduino, so first it's necessary to port it to both STM32 and native NRF51822 and then integrate it into the existing code. I'd say it's possible, but definitely not trivial.

@arnaud this can be useful if you are working with quadcopter swarms and you want to quickly exchange data between the quads.
