M600 + Beagle Bone Black or Tegra TX1 run samples one time

[natelannan-osu]

on newest OSDK, newest M600 firmware, djiosdk-* runs once and then on subsequent attempts to run produces:

ERROR/1 @ extractOnePackage, L364: Package does not have a valid DataBuffer

[natelannan-osu]

when attempting to use commands in example:

STATUS/1 @ getErrorCodeMessage, L626: startPackage
STATUS/1 @ getCMDSetSubscribeMSG, L708: SUBSCRIBER_PACKAGE_ALREADY_EXISTS

@natelannan-osu this error occurs when the sample doesn't exit cleanly - are you seeing segmentation faults or any other exit-related failures when you run the samples the first time?

[rohitsantdji]

@natelannan-osu we actually fixed a bug in the telemetry sample that was causing this post OSDK 3.4. Could you pull the latest commit and try again?

[natelannan-osu]

Sure thing. sorry for my slow response. Answering your earlier question, I did not see any segfaults when running the samples the first time. It reports everything closed successfully. I will test the latest commit tomorrow when I get to work.

I tried 3.4.1. Running djiosdk-telemetry-sample now produces a segfault due to an error in initVersion:

However, when I run 3.4 the first time I am successful:

running a second time is bad news:

Is this repeatable on 3.4.1 on your system? I see you've received an ACK_NO_AUTHORIZATION_ERROR on connection - what happens when you run it subsequently?
