I am trying to calibrate the Pixhawk 2.1 with the Black cube flight controller. For doing this, I used Qgroundcontrol in Ubuntu 18.04. I am getting an error that is the name of this topic. I tried installing the latest QgroundControl and install the Pixhawk v1.11 firmware again but still, the error is there.
Please let me know if you also encountered this error. Any lead would be appreciated.
Thanks in advance.
