I meant that you should flash the default PX4 firmware version 1.6.5, which is located in /etc/aerofc/px4/
Then, after checking with aero_get_version.py that you have the firmware version 1.6.5, please do a frame reset in QGC.
Since it's raining these days. I might need a few more days to test it out. I am just curious. Have you tested out Intel RTF with the latest firmware? It doesn't make much sense to me if the calibration doesn't work in the latest stable firmware. Anyway, I will give you feedback after I test it out.
