M600 [dji_sdk-2] process has died

fansdb68f33a

Hi!

I have an M600 with an onboard computer attach to it, the computer is running ubuntu 18.04, ROS Melodic. I'm currently using tag 3.8.1 of the Onboard-SDK-ROS, compilation work great, I disabled advaced_sensing, I have the proper app id and key, when launching the node, it connects to the drone but it crashes some seconds after starting... the output looks as follows:

------------------------------------------------------------------------------------

$ roslaunch dji_sdk sdk.launch

I have several questions:

1.- How can I prevent this crash?

2.- Is tag 3.8.1 the last tag that can be used for the m600?

Thanks a lot!!
