ESP8266 Community Forum

- Wed Mar 01, 2017 7:49 am #63182 Hello everyone, I'm having trouble reading data using the ESP8266 / Arduino Client.ReadStringUntil () function. I am using this function to read a url sent by a web application ... The problem is that the request is sent only once but the serial is read twice or more, even when typed the url by the browser ... Could someone Tell what is happening or how to solve it ?? Grateful !
