I don't find an answer in the documentation.

What is the purpose to support a second IMU? To drive 2 trackers with 1 wifi chip or to minimize error? From what I see in the code it seems to be no.1.
I skimmed the code, it seems if we do not have a second IMU, it will consider the first IMU "the second IMU".
In that case, the logic for the first IMU will be run 2 times for every event, which reports the same data twice. This does not seem correct.(It seems the difference is made by the INT pins?)
