• C++应程序实现修改设备IP地址、MAC、设备ID功能


    应用程序实现目的

    客户端通过广播发送信息,模组端的应用程序获取广播信息,解析信息修改相应的配置文件

    功能需求

    1. 烧写mac地址、设备序列号

    烧写完固件后,模组默认ip为192.168.0.200,默认mac地址为"A8:C3:15:00:00:00",默认device_id为"JS00000000000000"。需要修改mac地址、设备序列号后模组才能使用。

    mac地址、device_id不支持批量修改

    Request Body:

    {
        "magic_value": "AABB5555",    # 幻数
        "msg_type": "client",         # "client":搜索软件请求消息,"board":板卡回复消息
        "msg_cmd": "set_mac_id",      # 修改mac地址
        
        # 参数
        "mac": "A8:C3:15:00:00:15",
        "device_id": "JS01229110000900"
    }

    {
        "magic_value": "AABB5555",
        "msg_type": "board",
        "msg_cmd": "set_mac_id",
    
        # 返回结果
        "result": "ok"				 # "ok":修改成功 "fail":修改失败

    mac地址、device_id分别存储于/mnt/data/cfg/eth_cfg.cfg、/mnt/data/cfg/device_id。

    2.修改ip地址

    客户端通过设备搜索接口获取到所有在线模组的mac地址后,即可通过mac修改相关模组ip。

    模组收到消息后解析,mac与板卡mac地址相同时才进行ip设置,不同时忽略该消息。

    Request Body:

    {
        "magic_value": "AABB5555",    # 幻数
        "msg_type": "client",         # "client":搜索软件请求消息,"board":板卡回复消息
        "msg_cmd": "set_ip",          # 修改ip
        
        # 参数    
        "mac": "A8:C3:15:00:00:15",   # 待修改模组的mac地址
        "ip": "192.168.0.11"		  # 待修改模组的ip
    }
