Afif718 / ESP32-SIM7600-HTTPS-SSL-Data-Sender

A project using the ESP32 and the SIM7600 (A7670C) module for securely sending sensor data over HTTPS with SSL.

SIM7600 Data Sender (HTTPS & SSL)

Description

This project demonstrates how to send sensor data using the 4G SIM7600 (A7670C) module over GPRS securely with HTTPS and SSL. It includes error handling, session management, and a deep sleep feature to conserve power.

Features

• GPRS connection using the SIM7600 4G modem
• JSON payload creation for sensor data
• SSL communication with a remote server
• Session management with timeout handling
• Reconnection logic for network stability
• Efficient error handling

Hardware Requirements

• ESP32 development board
• SIM7600 modem (A7670C)
