ESP32 4G LTE to Google Firebase Realtime Database | A7670G Module Tutorial
In this video, we are upgrading our IoT projects from 2G to 4G! I will show you exactly how to connect an ESP32 to the Google Firebase Realtime Database using the SIMCom A7670G LTE breakout module.
Many IoT projects still rely on the older SIM800L (2G), but with 2G networks shutting down in many places, the SIMA7670G is the perfect, cost-effective 4G alternative. We will cover the wiring, the code, and how to send sensor data directly to the cloud over LTE.
