Prerequisites : NB open the card when the need to bind private ip (telecom operators setting), the effective link connection to 30 seconds, a time-out can not send data to the main server NB module. If you need to take the initiative to NB server module sends commands need to take telecommunications platform.

" The UDP network communication protocol specification"

Communication using GB2312 encoding format

Packet Format :

Identifier = the length of the device number # # # packet type task id # # package contents

Remark

Length : 4 if less than 0, the length of the identifier to the size between # #

1. The package is empty

HTEMP=0026#1533022506#Meter-001#01##

2. The package contains multiple fields

HTEMP=0043#1533022506#Meter-001#01#get-version@nb001#

3. The package contains multiple fields (inter-field divided by @ array within a field [{}, {}])
