SMS through traccar

To send a command to the tracking device using traccar, you need to have configured smpp? Or is it possible to do it without sms through the traccar platform?

It's possible without SMS.

Thanks for your answer Anton, could you give me a URL with information to give me an idea of ​​how to do it ?, or if Traccar has the online device configured just by sending the command, does it?

Yes, just send command to online or offline devices. For offline commands are queued until device is online.

Last question, I need some configuration in Traccar or just with this online and is compatible with Traccar my device the command will be sent without SMS?

Thanks for your help Anton in solving my doubts.

You don't need any configuration.
