  • Return code 6: "Exceeded reconnect rate limit. Please try again later."
  • Return code 7: "You have been banned from connecting. Please contact the MQTT broker administrator for more details."


  • Subscription failure moved to code -2
  • Connect timeout changed to 6 seconds to allow for 5 second delay in ban response from IO

These changes are live on Adafruit IO, and codes 6 & 7 have been submitted to the MQTT technical committee for comment.
