Sensor/Topic Debugging using the Listener Command

The uORB is an asynchronous publish() / subscribe() messaging API used for inter-thread/inter-process communication. The listener command can be used from the QGroundControl MAVLink Console to inspect topic (message) values, including the current values published by sensors.

:::tip Це потужний інструмент для відлагодження, оскільки його можна використовувати навіть тоді, коли QGC підключений через бездротове з'єднання (наприклад, коли транспортний засіб летить). :::

:::info The listener command is also available through the System Console and the MAVLink Shell. :::

:::tip To check what topics are available at what rate, just use the uorb top command. :::

The image below demonstrates QGroundControl being used to get the value of the acceleration sensor.
