T200 python manual control error

[EliotBR (Eliot)]

Hi @MokhtarYahia,

These comments (and the threads they’re from) may be relevant:

@EliotBR

I did some testing today and found that the motion should be explicitly set to stopped before arming, otherwise arming can sometimes resume the last thruster state from the last time the vehicle was armed.

@EliotBR

Note also the various failsafes that are built in. MAVLink connections expect to receive a heartbeat message at least every second (if not received the communication may be stopped), and when you’re controlling the vehicle it’s subject to the heartbeat failsafe , and rc override commands are subject to the pilot input failsafe and to RC_OVERRIDE_TIME .

You also seem to send your initial move command without checking if arming was successful. You may want to use master.motors_armed_wait() to wait for arming to complete.

I would also recommend adding a master.wait_heartbeat() call once you make the initial connection, so Pymavlink can determine which MAVLink version to communicate with (it should be MAVLink 2, and you’ll likely need to change your set_rc_channel_pwm to handle the extra 10 values that introduces, like in our example).

By the way, I’ve edited your post to have the code in a code block, which formats it and makes it easier to read, or copy for testing. You can read more about that in the Formatting a Post/Comment section of the “How to Use the Forums” post
