ESP8266 Community Forum

Hi all, i implemented a serious of IoT temperature sensor using ESP8266 and i update the sketch (when i made some changes) using OTA. Actually, i perform this operation from the Arduino IDE and i update one by one each ESP module. There is a way to upload the new sketch to every ESP devices in the same time?

Thanks for your support!
