Displaying - Sending Timestamp data to MQTT using SIM800L and ESP32
Learn how to send accurate timestamp data to an MQTT broker using an ESP32 and a SIM800L GSM module! This short demonstrates connecting the ESP32 to the cellular network via SIM800L, synchronizing time, and then publishing the current timestamp to an MQTT topic. This setup is essential for remote data logging applications where Wi-Fi isn't available, ensuring your sensor readings or event logs are always time-stamped correctly.
