LigiaCampos Dear user,
When you create a unit you should specify in the settings:
Device Category - Hardware
Device Type - Xexun TK103-2
After that, you can find in the unit menu - Settings - Common settings port and server on which you need to configure the tracker.
If your tracker supports DNS server format, then configure the tracker to:
Server Host - 12741.flespi.gw
Port - 26731
If your tracker only supports the IP server format (to see it, click the IP button next to the server value), configure the tracker to:
Server Host - 193.193.165.37
Port - 26731
You can see the tracker connected with these settings in the Toolbox (unit menu - Tools - Toolbox).
In case you are searching for a command to configure your tracker – please see the instruction for your tracker because commands for different tracker models can vary greatly.
