If you go to the web version of the application, then the blue dot is your location according to the device from which you are logging into the application.
It’s not completely clear from your description, but your tracker has probably still not connected or sent messages (if its status means “No info”).
For some users, such type of trackers work like ES-GP06 (Legacy). For example, also you can see information here https://forum.gps-trace.com/d/214-putting-ip-and-port-address-in-tkstar-905
However since trackers work with different manufacturers and models according to different protocols, it is difficult to say for sure whether your tracker corresponds to one of the protocols we support.
Please try to identify your tracker on id.wialon.net as ES-GP06
If your tracker is determined, take a screenshot, write down the name of the model of the tracker and the identified ID (may coincide with the IMEI, may be part of it with zero or no)
After that, return to the application in the unit settings (unit menu - Settings - Common Settings), specify the determined model and ID. After that, configure the tracker on the defined server and port.
