6 years ago Hi,
I see the byte code sent to the drone is [ '2', '1', '0', '18', '2', '0', '52', '46', '48', '46', '48', '46', '52', '0' ] which is not the command for checking all states of the drone. Its for setting the version for the libARCommands in the drone. And I don't have this function implemented in the view to support this command.
If you'd like to check the states of the drone, try to execute the checkAllStates example I have given as-is and let me know if it works.
Regards!

this occurs with the CheckAllStates function, and pops up in some other cases also.
here is the log of the CheckAllStates example:
