Link Management

The link module allows the user to add, remove and monitor the status of communications links to the APM. This can be done at any time.

It is useful for UAV systems that have multiple communications links. MAVProxy will automatically read the data from both links, no user intervention is necessary for link failover.

A link menu is available on the GUI console.

For ease of management, links can have labels.

link add

Add an additional communications link. This can be either a network address or serial port. For a serial port, the default baud rate is 57600. Use set baudrate xxx to change baud rate for any subsequent link add’s.

To add a label to a link, use :{"label":"LinkName"} after the link details. Note the link label must not have any spaces in it.

link add 127.0.0.1:14550
link add tcp:127.0.0.1:14550
link add tcp:127.0.0.1:14550:{"label":"3GMobile"}
set baudrate 115200
link add COM17

See the startup section for full details on link types

link remove

Remove a communications link. The ID or label of the link is used to identify the link to remove.

link remove 2
link remove 3GMobile

link list

List the active communications links, their ID’s and labels (if applicable).

link dataratelogging

Start or stop datarate statistic logging. If active, the statistics are saved in “dataratelog.csv” in the same folder as the tlog.

The statistics are useful for profiling and testing low-bandwidth datalinks.
