The Ulbotech protocol

The protocol of Ulbotech devices, a Chinese manufacturer from Guangdong focused on units that connect to the <strong>diagnostic port</strong> and read the vehicle's own data, not just position.

It is spoken by the T family — T353, T361, T371. It fits without cutting wires and starts reporting as soon as it has an APN and a server address.

Which port it comes in onOur server listens for the Ulbotech protocol on port 6072. That is the port you set on the device, together with the server address. Point it somewhere else and the data still leaves, but the server cannot read it.
Careful with what other sites tell youIt comes out in two seconds. <strong>Sell it as usage control and put that in writing</strong>, because if the customer understood it as anti-theft, the first theft becomes a complaint against you.
