NBIOT实现UDP协议的发送和接收(包含软件升级)

源码下载:

nbiot_module程序(java netbean)

UdpServer程序(C# vs2010)

前提条件:开NB卡的时候需要绑定私有ip(电信运营商设置)，链路有效连接为30秒，超时了服务器不能给NB模块主发送数据。如果需要服务器主动给NB模块发送指令，需要走电信平台。

《UDP网络通信协议规范》

通信采用GB2312编码格式

数据包格式:

标示符=长度#设备编号#任务id#包类型#包内容#

备注

长度: 4位不足补0，从标示符#到#之间的长度大小

1. 包内容为空

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

2. 包内容含有多个字段

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

3. 包内容含有多个字段(字段间用@分割，字段内的数组用[{},{}])

HTEMP=0261#WaterMeter-001#1520557005#03#buildid=44@edmid=37@meter=1228@denddate=2018-02-05 17:36:22@[{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}+{132,0.0000}]#
