Note:
A comma (,) is used to separate data characters. The character type is the American Standard Code for Information
Interchange (ASCII). (Hexadecimal is represented as 0x2C.)
Symbols "<" and ">" will not be present in actual data, only for documentation purpose only.
All multi-byte data complies with the following rule: High bytes are prior to low bytes.
The size of a GPRS data packet is about 160 bytes.
Descriptions about GPRS packets from the tracker are as follows:
