Could you please give me recommendations to choose the best and simple method to ensure communication in real time between Ethernet arduino and wireless module ?
Here the main parts of my project:
Ethernet arduino module to read data from a solar controller using Modbus TCP/IP protocol. (already done)
Need for a wireless module to receive data from Ethernet module in a local network ( still working on)
Assuming that there is a router and i'm using private IP address at the university, which wireless module is better to use in such situation ?
