FFT- not able to view IMU Batch Sample graphs after uploading the logs

Hello everyone,

Today, I conducted a flight for FFT. I enabled INS_HNTCH_ENABLE and set INS_LOG_BAT_MASK to 7 (to log data from all three IMUs) and INS_LOG_BAT_OPT to 1. After a 45-second hover flight, I extracted the .BIN files and uploaded them to the FFT UI to review the IMU BATCH SAMPLE graphs, but no graphs appeared—the screen was blank. This isn’t the first time I’ve encountered this issue; I’ve attempted FFT analysis three times before and faced the same problem each time.

can anyone please help me with this issue?

Not in this parameter file. It’s set at 2.

Use these:
INS_LOG_BAT_MASK,1
INS_LOG_BAT_OPT,4

Thank you for your valuable input.
I’ll test it out and let you know the results soon.
