能否通过rs232口给设备供电，或者可以定制串口供电的功能

I can only connect maximum 3 x EW11A TCP Clients to a single EW11A as TCP Server. Is this the maximum Clients?

I'm using firmware version 1.42.0. As you can see in the attached image, my computer connects MQTT but the HF2211A does not connect. How can I solve?

I cannot configure the IoT device HF2411 to send JSON messages to our web server. Please help.

断断续续购买咱们的设备有百十来套了，咱们的串口配网软件太麻烦了，建议参考友商的配网软件，如果第一次使用咱们的配网工具起码得个4 5 分钟，多网卡 还会出现无法识别到串口网关的问题，有时客户搞个半小时都没解决，这个问题和咱们销售3年前就提过，看贵司也没有更新响应，特此提个工单，希望关注，希望汉枫大卖。
