 <Protocol Version>: The protocol version that the terminal conforms to. The first two

characters point out the device type. As in the example, “06” means GV300. The middle two

characters point out the major version number of protocol and the last two characters point

out the minor version number of protocol. And both version numbers are hex digital. For

example, “020A” means version 2.10.

 <Unique ID>: The IMEI of the terminal.

 <Device Name>: The specified name of the device.

 <Serial Number>: A serial number which is equal to the <Serial Number> in the

corresponding command to distinguish which command the ACK message is for.

 <Send Time>: The local time to send the ACK message.

 <Count Number>: A self-increasing count number in each acknowledgment message and

report message. It begins from 0000 and increases by 1 for each message. And it rolls back

after “FFFF”.

 <Tail Character>: a character to indicate the end of the command. Must be “$”.

Note:

Only after both the command AT+GTBSI and AT+GTSRI are properly set, the ACK

messages and other report messages can be sent to the backend server.
