ESP32 reboots

[puhycz]

Hello,

I use EasyNextionLibrary for connect ESP32 with Nextion display. It crashes when I press touch buttons. One or two press is ok, but many presses or quick press again crash. I call myNex.NextionListen(); every 50ms.

Thanks, Jan.

Hello, Please try changing this file in the library's source files trigger.zip

[puhycz]

Yes, I tested it and it is ok. Many thaks.
