my problem remains the same if client always initiate request to the server and ask is there any work for me the server checks the data base that if some other person has clicked the button on website or not and then tells the emmbedded terminal about it then ts not a real time function.
cant some how i can make the whole process real time operation. No. Not unless you make your embedded terminal a server which is going to be more complicated to code than making it a client. This means that your node must have a public IP address or a router/proxy that forwards requests to it so that the company website can connect to it. This also increases the security risk for your embedded terminal since anyone in the world could also connect to it and try to hack their way in. This has been explained to you more than once, Karandeep. What exactly are you confused about? Please tell us: 1. Where is the webserver? That is, is it a normal website on the Internet like 8052.com? 2. Where are your embedded terminals? Do they have their own Internet connection dedicated to them only, or are they going to be on a LAN that has a single connection to the Internet? Regards, Craig Steiner |
