NB-IoT Project with ESP32 and SIM7080

This project demonstrates how to use an ESP32 microcontroller with a SIM7080 module to perform NB-IoT connectivity and execute a GET request using AT commands.

Project Overview

The project involves setting up an ESP32 to communicate with a SIM7080 NB-IoT module. The aim is to send an HTTP GET request to a specified server and handle the response.

Components

• ESP32: The main microcontroller used for the project.
• SIM7080: The NB-IoT module responsible for network connectivity.
• Wires and Connectors: For connecting the ESP32 to the SIM7080 module.

Connections

1. ESP32 to SIM7080:
   • TX of ESP32 to RX of SIM7080
   • RX of ESP32 to TX of SIM7080
   • GND of ESP32 to GND of SIM7080

Software Overview

1. AT Commands:

   • Used for configuring the SIM7080 and performing the GET request.
   • Examples include setting network credentials, initiating a connection, and sending an HTTP GET request.

2. **ESP-IDF *:

   • Use ESP-IDF to program the ESP32.
