Hi,
I'm struggling since days now with connecting my D1 to a ProMini via I2C.
I'm using the Wire lib and added that additional line
Wire.setClockStretchLimit(15000);
If I2C data freezes both devices are still outputting text via Serial , debugging Leds are still blinking,but analyzed with a LA there is absolute no activity on SCL and SDA. Only if I reset the ProMini or the ESP then it will work again
Are there are any ideas if there's a problem in the ESP8266WiFi.h core?
edit: when shorting-out A4 and A5 then it works again also..
