RC Override Control (65535) Not Working

[EliotBR (Eliot)]

Hi @Marios, welcome to the forum

@Marios

the override value (65535) does NOT work.

What do you mean by this? 65535 is the “ignore” value, which means that channel doesn’t get updated. Channels set to 65535 in an rc_channels_override message will maintain whatever value was already stored, which can potentially cause issues with other controls.

This quote (and the post it’s from) are relevant:

@EliotBR

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.

If you’re interested I’ve made an example program here, which sends regular heartbeats and handles arming/disarming and setting the flight mode.

I would also recommend you look into the failsafes and timeouts

@Marios

If i use Beta or Developement versions the override value (65535) works, BUT the pressure sensor is not recognized ( I use the Bar30 High-Resolution 300m Depth /Pressure Sensor) so I cannot use “depth hold” mode, only stabilize.

In case you want to try running beta/devel anyway,

@EliotBR

ArduSub beta recently had a couple of updates that apparently messed up a default parameter for the depth sensor. The issue should be fixed if you

try setting BARO_PROBE_EXT to 768 and then reboot.
