Hi!

Just follow the getting started guide https://www.bitcraze.io/getting-started ... ng-system/ using ids 0 to 3. You don't have to do anything special, the anchors synchronize using the UWB radio.

If you plan to do 3D positioning, 4 anchors might be a bit too few.
If you only want 2D positioning, compile the Crzyzflie firmware with the LPS_2D_POSITION_HEIGHT flag, see https://github.com/bitcraze/crazyflie-f ... xample#L77

If you are interested in implementing your own algorithm, you might want to use our code for inspiration.
The anchor is mainly implemented in https://github.com/bitcraze/lps-node-fi ... _anchor3.c
The tag is mainly implemented in https://github.com/bitcraze/crazyflie-f ... Tdoa3Tag.c and https://github.com/bitcraze/crazyflie-f ... s/src/tdoa
