//	History
//	2017-08-15  Dan Ogorchock  Created with the help of Joshua Spain
//  2017-09-05  Dan Ogorchock  Added automatic WiFi reconnect logic as ESP32 
//                             doesn't do this automatically currently
//  2018-01-01  Dan Ogorchock  Added WiFi.RSSI() data collection
//  2019-05-01  Dan Ogorchock  Changed max transmit rate from every 100ms to every 
//                             500ms to prevent duplicate child devices
//  2020-06-20  Dan Ogorchock  Add user selectable host name (repurposing the old shieldType variable)
