Setup:
Adafruit Feather Huzzah ESP8266
ADS1015
Blynk Lib: 0.6.1
App Ver: IOS 2.26.1(9)
Here is my issue. I’m not new to using blynk or building projects but I’m stuck at this problem. My two BLYNK_WRITE functions will not trigger. When you move the slider or press the button in the app nothing happens. The serial debug info shows nothing. It doesn’t get the command/trigger/whatever you wanna call it. Interesting thing is when I hard reset my board the slider in the app always jumps back to 3.25. I’ve been staring at this code for over a day and at a loss. I’m using the Arduino IDE to upload (tried both OTA and serial) and I have tried reinstalling the Blynk library and refreshing my auth token. No luck. I realize the two while loops add delay to Blynk.run() but have done longer delays in while loops and not had issues.
I even changed the while loops to only 500ms with no change. What am I missing? Thanks
