Freematics one plus
This is what I did when I was testing one of their devices:
https://www.traccar.org/freematics-configuration/
If you got the Traccar edition option, then it should be pre-configured with the demo server by default, so in theory you don't need to do anything there.
First time checking this out? Not sure to begin. Do I power it up to configure? Do I need to change firmware? I want to start w testing with tracers servers before I try to build one. Any suggestions or help would be appreciated.
