SSH1106 no update after webserver message about printer-monitor HOT 7 CLOSED

from printer-monitor.

Ok, I know your problem now. The firmware uses LED_BUILTIN and that by default is using D4 (Wemos D1 Mini Default) This is where you get the blue flashing working LED light. Well, you have told it that your OLED is now using D4 pin and that is the issue... when the firmware goes to flash the LED -- it locks up your OLED display. I have seen this before. You can either change your pins or disable the the built in LED on the Wemos by changing the pin to it in the Settings.h file:

const int externalLight = LED_BUILTIN;

Change LED_BUILTIN to D1 -- that will disable the flashing but let it work. I would say if you want the LED to flash then change your display pins.

Have you updated the core library for ESP8266 -- look down in the bottom right of your Arduino IDE and see if it says (no SPIFFS) You must compile with at least 1M for SPIFFS or it can't load settings from the file system.

I'm using esp2866 core 2.4.2, adafruit gfx lib 1.3.6 and oled driver for ssd1306 v4. I recompiled with 2M spiff reserved, same behavior.
Below the log, seems all is ok. The display is freezed on the message to connect to web server http://192.168.34.48:80/.
Maybe it is because can't reach the octoprint server? On the other configuration I tested with SSD1306 all is ok even if the octoprint server is off...

What happens when you pull up the web interface? It looks like it is running from the Serial Monitor logs you shared. Can you try loading the sh1106 compiled binary that was shared in the 2.3 release? You can do that through the "Firmware Update" link in the web interface.

Web interface seems ok and loads al configurations from SPIFF correctly. Using PIN D3 and D4 if I use your binary I will not see anything on screen (you use D6 and D8 PINS). Can you compile a custom version using D3 and D4 PIN?

Confirmed, problem solved changing to D1 the led_builtin! Many thanks
