Configuring send command

Hello, how are you? I hope you are doing well.

I have a few questions regarding sending commands. www.traccar.org/commands/

1. The custom command data has to be in hexa? Or is it plain text?
2. I've configured the save command but on the "Then link it to a device" screen I don't see the save button.
3. I also don't see the "send command screen"

Thank you in advance, Regards.

If you create a saved command and then assign the saved command to the device (device/connections). Then you will see the saved command in the device popup window on the map where you see the arrow.

1. Depends on the protocol.
2. Linking doesn't have a save button. It's saved automatically.
3. Not sure what you mean by this. Provide details.

I can help here.

1. As Anton said, it depends on the protocol. Some protocols require raw hex data, others support plain text. For teltonika trackers, Traccar does the conversion from plain text into their "Codec 12" for sending data to the tracker.
2. Anything in Traccar which is edited using the Connections menu (the one with the link icon) does not need to be saved, it's applied immediately.
3. There is no Send Command "screen". You select a Device and on the popup for that device there is an up arrow with a horizontal line above the arrow. When you click this, a new window opens which lists the available commands for that device.

Note that for commands to be available the command must be linked to the device AND the user.

Hello Track-trace, Anton and Kaldek.

Thank you for the quick response and solutions. I now have the commands configured.

Have a great day
