Both ESP's are sending data to TingSpeak using WiFi. I'm programming the ESP's with the Arduino desktop version for Windows 10
When testing the program (connected to PC) everthing works fine. But, when using the ESP stand alone powered by an USB -adapter it takes usually 5 to 10 retries to get the program running.
What do I need to do to get the program running at power up stand-alone -using an usb-power supply?
specific GPIO high/low? coding?
