Arduino+ESP8266 translate analog data to Blynk

@legionercheg I think you now have the dreaded “Failed to disable echo” issue.

This is normally associated with incorrect baud rates.

@esa’s 2 point guideline for “shields”, 7 points by Blynk and 10 points if I bother to make a guideline, only works if you go straight for Arduino with ESP as shield. Many users try the ESP standalone method first and this removes the AT firmware. It is then much more involved.

Look through this thread [SOLVED] Arduino + ESP8266 ESP-01(AI-Cloud, Black Version) including the useful 7 point guide by @dwadia
