WiFi pulls pin 15 low

Postby Pibbotley » Wed May 30, 2018 1:43 pm

Investigating a problem with a script not outputting high on pin 15, I found that the problem (feature?) was caused by the WiFi library (Arduino IDE) pulling the pin low, possibly associated with wifi event handling. This can be demonstrated using the example script WiFiClientEvents and adding a digital write high to pin 15 in the loop. Is this documented anywhere?

see https://github.com/espressif/arduino-esp32/issues/1568
Worked for me, although I am not completely sure if your issue was the same as mine.

Thanks, updating to latest fixed issue. I notice that a 'major WiFi overhaul' was committed on 24/06.
