Have good day. I have the following problem with mission planner versions higher than 1.3.61, on pixhawk 2.4.8 with firmware fmuv3 versions 4.3.5 and 4.3.7.
FS_GCS_ENABL=1
FS_LONG_ACTN=1
FS_LONG_TIMEOUT=30
After the power is applied after time set as long failsafe timeout, the mode changes to RTL, even if the mission continuation in auto is set. At the same time, the quality of the packets is 100%, the problem is manifested both through the 3DR radio and through direct connection through the USB port.
That is, if the long failsafe timeout is set to 30 seconds, then 30 seconds after the power supply, pixhawk changes the mode to RTL. everything works correctly on mission planner 1.3.61 and older versions.
Thanks
The problem is solved. In the settings, there was a GCS ID other than 255. Changing this parameter to 255 solved the problem.
