Arduino IDE sketch for ESP32 + SIM800 (MQTT)

The battery-powered mobile device is built on the ESP32 architecture.

The device wakes up every hour (deep sleep), receives data from the sensors, sends it via the GSM channel via the SIM800 module via the MQTT protocol to the server and goes back to sleep.

There is a sample code.

All sensors are connected via the i2c or 1-wire bus: ADC1115 (2 pcs.), BME280 (2 pcs.), DS18B20.

Basic requirements for the sketch:

1) Interaction of ESP32 and SIM800: GPRS connection, positioning by base stations.

2) Collecting data from sensors (about 10 pieces) and parsing them into JSON format.

3) Verification of sending data to the server and re-sending in case of communication failure (QoS).

4) Separation of sensors into two i2c buses.

5) Firmware update via OTA (MQTT).

Phased delivery of work is possible.

There is a sample of a working sketch, but without some features.
