@Brian Kilberg
both IMU and lighthouse working together
need to fix attitude estimation, by ignoring gravity
using Mdgwick and MUKF (Multiplicatif Unscented Kalman Filter)
had to play with the programming configuration, “set 3rd number to 4“ (should be the length of the short pulse)
had to tune the “loop delay“ to have the system run for >1min
@Titan Yuan
BLE TX Cal by tracking 15.4 RX Freq
WIP on merging BLE code (https://github.com/PisterLab/scum-test-code/pull/17 )
working on paper on temperature calibration
delta f between BLE TX and 15.4 RX is approx the same
issue with not receiving packets from OpenMote
@Kristofer PISTER on 15.4 RX, you can look at IF, this allows you to see your frequency error directly
