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
