Data Compression Mode – CCC
Device communicates through Meitrack protocol. The header and tail of a data packet stay unchanged, but the middle part of
the data packet has been uploaded with CCC data compressed format.
Note: Only proactively-uploaded data (such as timing, heartbeat, or alarm events) is uploaded in CCC data format. Commands
sent by the platform and replied by the device have the same format as the commands in Meitrack GPRS Protocol.
