I'm looking for someone to help me with an upcoming project.
I need to achieve the following.....
1. Master (Server) RPI connected to wired LAN which transmits multicast TCP / UDP message when a GPIO is high or a button clicked on a webpage.
2. Several (Client) RPI's also connected to wired LAN which all receive the multicast message then output serial data to control an external processor attached to each RPI
3. Client RPI to send confirmation message back to master confirming action.
I would also like to have a web page / display on the master RPI to report the status of each client. and the possibility of sending more than one serial command.
If you are interested please get in touch and we can talk I think I understand the basics involved but don't know if im going to have time to learn how to put it all together into a working solution.
