Think+7 bit of Binary Zero (bit) (such as Binary Zero 0000000-01111111, be incremented by one successively), another data packet
Sequence identifier (can such as be represented in binary as 10000000~11111111, press 1 successively for the serial number mark of binary one+7bit
It is incremented by)；Also, the serial number mark of data packet carries out one cycle resetting at interval of 128 data packets.Then, sending device will
The data packet that serial number identifies has been added to pass to next layer of carry out bottom encapsulation, and data package size meets bottom demand.
For example, the serial number mark (i.e. first identifier) of the first data packet is 00000001, the serial number of the first data packet identifies
(i.e. second identifier) is 10000001.At this point, first identifier and second identifier are preset corresponding mark.
