Hi @khoih-prog
Yes, it's been some while. I'm back at it, adding OTA to all my sketches.

Request: I have forgotten how to cause the Config Portal to come up from a ESP32 or 8266 sketch.
I thought Blynk.clearConfigData(); followed by a ESP.restart(); would do it. The restart works, but the Confog Portal doesn't post.

Would you be kind enough to (re)explain how to get a Config Portal up besides mechanically using DRD? (I'm going for touch-free devices!)

Thanks again for all your help, and in advance.

 { // Get the Reset button value, Hit Reset and reboot if = 1 int buttonVal = param[0].asInt(); Serial.print ( " " ); Serial.print ( "RESET Button Hit with value = " ); Serial.println ( buttonVal ); if ( buttonVal == 1 ) { Serial.println ( " \n REBOOTING " ); Blynk.clearConfigData(); delay ( 8000 ); ESP.restart(); } } 

I've been using your Blynk_WM on SONOFFs and on a variety of ESPx monitors. WM Library has been helpful, stable, useful and reliable to me. Thanks.
