QGC keeps crashing when sentinel drone is reconnected

[Dawid Mościcki]

Hi, Im using sentinel drone.
When drone is connected for the first time to QGC everything works. After lost of signal and reconnection or just powering off drone then powering up QGC is crashing.

In my other project this type is behavior was caused by my custom px4 module with new set of parameters. Maybe it's possible in Your software as well?

@Zachary-Lowell-0 This could be probably caused by missing sdlog_mode parameter. Maybe it was introduced in one of the commits that modified logger.cpp in src/modules/logger ?

@Dawid-Mościcki Perhaps you can ask the QGC development team for some help in narrowing down what is causing QGC to crash. If you think there is a missing parameter then in your /usr/bin/voxl-px4-start script add a new line to touch the parameter so that QGC will see it. (e.g. param touch SDLOG_MODE)
