- Fri Dec 12, 2014 3:58 pm #4702 I've a problem. I have my little ESP-01 talking to my Arduino via AT commands - and acting as a TCP/IP listener- but while it's doing that day in/day out - how can it go off and get info from a web page without losing the listening ability? The plot thickens..

Do your server log and time query, and then return ro receive the requests. Now, if you have hard real time requirements, then a single ESP is probably the wrong solution. I'd say, in this case, TCP/IP is the wrong solution.
