Simple GSM shield Manager for Blynk and ESP32 / ESP8266 boards, with or without SSL, configuration data saved in SPIFFS / EEPROM. This library enables user to include both Blynk GSM/GPRS and WiFi libraries in one sketch, run both WiFi and GSM/GPRS simultaneously, or select one to use at runtime after reboot.
