ADAFRUIT_MQTT_Client Login and Pwd in loop() Moderators: adafruit_support_bill, adafruit

I know that ADAFRUIT_MQTT_Client must be istantiated before setup()
but my MQTT_login and MQTT_password are stored in EEPROM and as
you know I can read from there only in setup() or loop().

How resolve this ?

This was asked before and there was no answer. Anyone?

You may want to switch to the Adafruit MQTT Library.

Could you try storing your Adafruit IO Username and Active Key in EEPROM, and then instantiating the MQTT client here:
https://github.com/adafruit/Adafruit_MQ ... 66.ino#L44

The MQTT client doesn't connect to Adafruit IO's MQTT server until the MQTT_connect function is called.
https://github.com/adafruit/Adafruit_MQ ... 6.ino#L111

What you might want to try is reading your credentials within the MQTT_connect function and create a new Adafruit_MQTT_Client in that function with the credentials read from EEPROM.
