MAVLink Shell

The MAVLink Shell is an NSH console that can be accessed via MAVLink over serial (USB/Telemetry) or WiFi (UDP/TCP) links (in particular, on NuttX-based systems like: Pixhawk, Pixracer, etc.).

它可用于启动系统指令与模块，并得到输出信息。 While the shell cannot directly display the output of modules that it does not start, it can do so indirectly using the dmesg command (dmesg -f & can be used to display the output of other modules and tasks running on the work queue).

TIP

The QGroundControl MAVLink Console is the easiest way to access the console. If the system does not start properly you should instead use the System Console.

1. Shut down QGroundControl.

2. 安装依赖项

   pip3 install --user pymavlink pyserial

3. Open terminal (in PX4-Autopilot directory) and start the shell:

   # 通过串口
   ./Tools/mavlink_shell.py /dev/ttyACM0

   # 通过 WiFi 连接
   ./Tools/mavlink_shell.py 0.0.0.0:14550
