We have 20 Digi modems (Connect WAN 3G) and 20 mobile sim cards with fixed mobile IP addresses. We have serial device outputting short text string every second. We would like to transmit this string to 19 other modems to have it outgoing from serial ports.
What I’ve managed so far is to establish communication between two modems (one is sending and the other one is receiving the data string) based on TCP protocol. When it comes to two or more receivers I don’t see a possibility to assign more than one IP address to send to on transmitting DIGI. It looks like interface for UDP protocol is more suitable for our target: there we can set up as many receiver’s IPs as we like, but I had no luck with getting it working via UDP.
So, the problems remains unsolved however hard I’ve tried.
Any help of Yours would be very much appreciated
Thank You in advance
