As an example, the Queclink protocol encoder file in Github contains several pre-saved commands:
https://github.com/traccar/traccar/blob/master/src/main/java/org/traccar/protocol/Gl200ProtocolEncoder.java
The Teltonika protocol encoder doesn't include any pre-saved commands, just a "custom" one:
https://github.com/traccar/traccar/blob/master/src/main/java/org/traccar/protocol/TeltonikaProtocolEncoder.java
I've installed an FMB204 and will be connecting a relay to allow for engine stop and start commands.
When I go to the commands option to send a command, there are no commands for the device.
When I try my Queclink device, various commands already appear in the drop-down.
I thought Teltonika was a well-supported brand, am I doing something wrong or does the Teltonika protocol in Traccar not support commands for the FMB204?
