To connect your tracker using the Maxtrack protocol, you need to have a maxtrack channel created first.

Point your tracker to the channel's domain name:port via SMS or configuration tool provided by the vendor.

Then create a device instance for your tracker and use a 15-character IMEI (usually specified on the tracker casing) in the ident field.

Use the Toolbox tab on the device screen to check if the messages are coming.

It is possible to configure Maxtrack devices OTA using the flespi web-based configurator tool. To connect Maxtrack to Wialon or another platform via flespi please read this article.
