Using Lopy to get TDOA

[April]

Hi there, i am new to lopy. Currently, i have a project regarding to use the 2Lopy+expansion board(gateway, receiver) and 1Lopy+pytrack board (node, transmitter) where the node will send out the signal and transmitted to the 2gateway with different time by obtaining their Time Difference of Time Arrival. May i know how can i easily cope with this kind of problem. Thanks in advance.

Sorry to say but time difference of arrival between two radio transceivers is actually a very difficult problem, you’ll need more hardware than the LoPy provides and/or VERY clever algorithms.
