Never assign DataStream to a pin that does NOT exist

[Ibrahim_Roshdy]

I assigned pins # 6 & 7 to a digital DataStream at an esp32 template, and spent the next two days troubleshooting code, rolling back, replacing hardware and talking to pillows because of that mistake (or bug). RTOS was crashing giving me the “Guru Meditation Error: Core 1 panic’ed” just the moment after “Ready (ping: XX ms)”. i was aware that those pins does not exist from the beginning; but i couldn’t find esp32’s actual pin numbers at digital DataStream-PIN drop down list, despite selecting ESP32 hardware at template’s info. it is my mistake but i didn’t expect Blynk library to behave that way.

Hope that helps somebody.

I’d take that advice a step further, and say don’t use digital pins at all, until this issue is sorted-out…

Can't read Digital & Analog By ESP32S board

@Dmitriy can you explain how the analog and digital datastreams are meant to work for various hardware types? If I choose ESP8266 in the web console I see 5 analog pins available numbered A0-A4. I also see pins numbered 0-14 which I assume represent the digital pins. The ESP8266 has one analog pin, A0. If I choose digital pins for the ESP8266 I see 14 pins, numbered 0-13. The ESP8266 has the following GPIOs: 0, 1, 2, 3, 4, 5, 12, 13, 14 & 15. If I choose ESP32 then I see the same analog pin…
