Hi!
Unfortunately I don't think that has been implemented. If you want to have a go at it you can find the implementation in the Crazyflie here
https://github.com/bitcraze/crazyflie-f ... Tdoa2Tag.c
It is probably fairly straight forward to convert it since it uses the same DW1000 library. The output from this code is the raw TDoA values though and to get a useful position out of it you will have to some sort of estimator after that. Most likely the Node will not have enough CPU-umphf to do that, so you probably have to stream the TDoA values out from the Node into another device for further processing.
