If you want to use our application with the AT08F tracker, you can try to select AT08 from the legacy category when creating a unit in the list of devices.
After creating a unit in the application, you will see the server and port on which you will need to configure your tracker.
Also, information about the server and port after creating a unit can always be viewed in the Settings-Hardware section.
If this does not help, please write to us at email@example.com, send us login, device photo and if you have screenshots of device manual. We will try to help you.
Also write a link to this topic in your email request, so that we can understand that this is you.
