GT02B Command Settings

Good afternoon,

I need help with GT02B track device from blueberry technology. I need to know witch command setting i have to use to make that device point to wialon server:  193.193.165.165 and port : 20769?

We tried to use all commands become in Manual comes with devices, but we always get this error " Format Wrong!". We can not get in touch with  blueberry technology by any of the contacts we used to by those devices, email, website even whats-app. They website takes us to unknown links, by email we never get response, Skype always offline whats-app also,.

If someone here know how the worked command settings that should help us to make it point to wialon host please provide it for us.
