电表DLMS协议升级流程分析

最近进行电表DLMS的升级，特记录下升级流程

1、初始化

------------------------------------------------------- 初始化 --------------------------------------------------

1、Set ImageBlockSize 设置传输块大小(没帧多少个字节)

c10141001200002c0000ff0200060000017c 
c501c100 

2、image_transfer_initiate 清空上次升级的文件(设置文件名和总共需要下发文件的大小)

c30142001200002c0000ff01010202090854413235525657330600033d9c 
c701c20000

3、image_transfer_status 查询状态，初始化是否成功Image transfer initiated

c40181000482022d000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000

6、image_verify(data) 激活验证完整性

c30181001200002c0000ff03010f00 发00 
c701c10000

------------------------------------------------------- 激活 --------------------------------------------------

7、验证是否成功 image_transfer_status 校验已成功《可以进行激活了

c00181001200002c0000ff0600 
c40181001603

8、激活 image_activate
