ESP32_FOTA_via_EC25-module

FIRMWARE OVER THE AIR for ESP32 via EC25 4G module through AT Commands.

DESCRIPTION

The main motive of this project is to make Firmware Upgrade for ESP32 from WEB 🌏. The ESP32 has its own WiFi connectivity and FOTA can be upgraded from that. There are many examples available for WIFI_FOTA for ESP32. But in Our project the main motive is to download the firmware from http server via GSM 📶 module with help of Simple AT Commands 🔥.
