/*iGrill BLE Client
In order to setup the iGrill BLE Client or force the device back into configuration mode to update WiFi or MQTT settings you will need to
press the reset button on the device twice to trigger the double reset detector.
You can configure the Number of seconds to wait for the second reset by changing the DRD_TIMEOUT variable (Default 10s).
Once the device has booted up in configuration mode you will need to enter a password to enter the configuration/setup panel.
From this configuration panel you can configure the device to connect to your home WiFi network as well as configure the MQTT Server Information.
NOTE: You can enter in information to connect to two wifi networks, and the device will automatically choose the one with the best signal.
If you only have a single network you want to use this device from you can leave the second SSID and Password field empty.
The Credentials will then be saved into LittleFS / SPIFFS file and be used to connect to the MQTT Server and publish the iGrill Topics
************************************
* Configuration Portal Information *
************************************
Wifi SSID Name: iGrillClient_<ESP32_Chip_ID>
Wifi Password: igrill_client
NOTE: You can change this from the default by editing the code @ Line 58 before uploading to the device.
Wifi MQTT handling based on the example provided by the ESP_WifiManager Library for handling Wifi/MQTT Setup (https://github.com/khoih-prog/ESP_WiFiManager)
