Unable to start vehicle not ready (mission plan mode)

Hi every one

  • First at all, thank you for your kindly help :slight_smile:

Secondly: I have a tbs-discobery drone with a pixhawk and a 3DR/compass gps. I follow this link:

  • Secondly:
    Well, I read that USB3 is known to be an effective GPS jamming source. So, I have wrapped under the GPS and between the USB3 from Jetson TX2. And, amazingly The GPS status was as follows:

GPS Count 17
GPS lock 3D DGPS lock
HDOP 0.7
VDOP 1.1
Course over ground 219.4

However, when I set up or add way points in mission plan. I could successfully load the mission and when I wanted to start the mission I got the error:

““Unable to start vehicle not ready”” Even though I tried few times just one log file is available.

I read that the log files only generates when the drone is armed and disarmed, right? well, in that case I armed and disarmed the drone once with the RC-controller.

But, the question is: How can get the log file if it does not allow me to arm and start the mission planer flight mode.

I have the link that has been generated by the flight review.

I share it here:

Also, after I loaded the first mission plan and failed. I set up new mission plan and then when I wanted to load the way points mission, I got the error: ““Mission write failed to send final ack.””

I am looking forward to your replay.
