I'm trying to build a system where multiple users can establish connection to same web socket server to communicate with embedded programmed HARDWARE DEVICES. It should be one to one communication between user and device. So far, I have worked with Ratchet and able to send and receive data over one user and and one device but my challenges is, multiple users [ Android devices ] can communicate with multiple devices over same web socket server. So, how specific user can communicate with their device over web socket server.
