连上网口不能发现设备

设置MODBUS 功能灰色，如附件

小精灵与电脑直连，静态IP设置TCP服务端，可以与上位机的客户端通讯，但是设置成TCP客户端不能与上位机通信。IP设置没问题，基本的通讯原理还是懂的，用过其他家的类似产品设置是一样的。是需要注意啥吗？

Hi! We are partners of Mill International for which your company delivered LPT120 and LPT220 chips with adequate firmware. Now, we have discovered some issues with Android firmware which is made by you. In this file we discovered flooding packets on port 47777 (hiflying-iots-android-smartlink-8.3.3.jar). Could you provide us non-compiled version of it? Would be perfect to get whole source code

hi i need the default wifi password to connect to the device, and other related software and user manuals would be appreciated as well. thanks

【设备实际型号PW11，S/N：34EAE703F806】 PW11接485型气象站，设置为tcp client，已经证实过server端可以基于modbus-tcp透传的方式读取传感器数据。现在想利用PW11的脚本，定时轮询发送modbus读保持寄存器的报文，然后在socket服务端接收Modbus-tcp响应报文。利用TIMER和Send(UART,uart0,cmd)等已经实现了传感器读取（用串口工具检查过了，发送和接收的数据都正常），但socket服务端收不到数据。尝试过RECV UART uart0然后SEND(SOCK,netp,data)等方式，都没有效果。请问这个需求对应的正确写法应该是怎么样？有没有例程能提供给我参考一下？谢谢！盼复！
