crazyflie communication

Post by SH_Lee »

We're trying to communicate between drones in the following ways:
I'm considering three things to implement this.

1. uwb communication using LPS deck.
2. Multiple p2p communication using nrf.
3. Multi-communication using additional modules such as zigbee.

We are looking for communications that do not affect stable flights.
We are considering options for number 1 and 2 that are not required by additional modules first, and if this is not possible, we will consider option 3.

We welcome any communications case or information using the LPS deck.
Also, if you have any other options, even if it's a third, please tell me whatever information is involved.

And if there's any other way I haven't thought about it than the three above, please tell me.

Hi!

1. This has not been officially implemented yet but it is in discussion in the repository: https://github.com/bitcraze/crazyflie-f ... issues/576. There is also a pull request available that we can not merge just yet (https://github.com/bitcraze/crazyflie-firmware/pull/580).
2. I don't know if I shared it with you yet but there is documentation how to setup p2p, which I recommend to implement this using the App layer. There is currently a p2p example avaliable that uses the app layer on the crazyflie-repo (broadcast only though): https://github.com/bitcraze/crazyflie-f ... er_to_peer
3. Yes you can do that as well, but its not the best thing to do. Not saying that zigbee or such are bad means of communication, but adding more modules on the crazyflie will take away energy that can be used for other modules and resources (such a small platform such things matter). It makes more sense to use the onboard communication means there are already on the crazyflie (so in that sense I vote for the NRF if you don't need good distance measurement between them)
