Messages

The Messages tab of the Properties panel enables you to send debug messages to individual drones. Available messages for each supported autopilot type are summarized below.

Table 1. Supported messages with ArduCopter firmware
usage	description
`calib COMPONENT`	calibrate the given component, where `COMPONENT` can be one of `accel`, `baro`, `compass`, `gyro` or `level`

`color #RRGGBB`	override the light module with the given RGB color (expressed in hexadecimal numbers)
`color NAME`	override the light module with the given color if `NAME` is recognized as a color name (e.g., `red`)
`color off`	stop overriding the light module with GCS-based colors
`mode NAME`	switch the drone into the flight mode given by `NAME`, such as `show`, `land`, `rth`, `loiter` etc. (works only on ArduCopter-based drones)
`param NAME`	get the value of an autopilot configuration parameter given in `NAME`
`param NAME=VALUE`	set the value of an autopilot configuration parameter given in `NAME` to `VALUE`
`servo CHANNEL VALUE`	set the (1-based) servo channel (`CHANNEL`) on the UAV to the given raw PWM value (`VALUE`)
