I want to know mango Connected to 4G device and controller back to device. 4G device using sim mobile and not fix ip address. 4G device via modbus tcp protocol. I think it would make the mango a modbus server and let the 4G device connect. I see the function of the mango. No modbus server protocols. Is there a way to get the 4G device connected to the mango to read the data and control back to the device.
