-/****************************************************************************************************************************
- * Geiger_Counter.ino
- * For ESP32 using WiFi along with BlueTooth
- *
- * Library for inclusion of both ESP32 Blynk BT and WiFi libraries. Then select one at runtime.
- * Forked from Blynk library v0.6.1 https://github.com/blynkkk/blynk-library/releases
- * Built by Khoi Hoang https://github.com/khoih-prog/BlynkGSM_ESPManager
- * Licensed under MIT license
- * Version: 1.0.1
- * 
- * Based on orignal code by Crosswalkersam (https://community.blynk.cc/u/Crosswalkersam)
- * posted in https://community.blynk.cc/t/select-connection-type-via-switch/43176
- * Purpose: Use WiFi when posible by GPIO14 => HIGH or floating when reset. 
- *          Use Bluetooth when WiFi not available (such as in the field) by by GPIO14 => LOW when reset.
- *
- * Version Modified By   Date      Comments
- * ------- -----------  ---------- -----------
- *  1.0.0   K Hoang      25/01/2020 Initial coding
- *  1.0.1   K Hoang      27/01/2020 Enable simultaneously running BT/BLE and WiFi
