  • Arduino board:

ESP8266

platform = espressif8266
board = esp12e
framework = arduino
  • Arduino IDE version (found in Arduino -> About Arduino menu):
PlatformIO, version 4.3.4
Using Adafruit MQTT Library version 1.3.0
  • List the steps to reproduce the problem below (if possible attach a sketch or
    copy the sketch code in too):

Using platform.io, compile project that uses Adafruit_MQTT_Library
