/*
ESP8266/ESP32 publish the RSSI as the WiFi signal strength to ThingSpeak channel.
This example is for explaining how to use the AutoConnect library.
In order to execute this example, the ThingSpeak account is needed. Sing up
for New User Account and create a New Channel via My Channels.
For details, please refer to the project page.
https://hieromon.github.io/AutoConnect/examples/index.html#used-with-mqtt-as-a-client-application
Also, this example uses AutoConnectAux menu customization which stored in SPIFFS.
To evaluate this example, you upload the contents as mqtt_setting.json of
the data folder with MkSPIFFS Tool ("ESP8266 Sketch Data Upload" in Tools menu
in Arduino IDE).
This example is based on the thinkspeak.com environment as of Dec. 20, 2018.
