Firmware development for ESP32 ESP-MDF

The goal of the project is to create an esp-mdf mesh node that collects readings from SCD30 CO2, Temp, RH sensor. Display the values on a SSD1309 LED display. Transmits the current readings to the root node at a minimum interval. If acting as root node handle communications to and from the mdf network and an http server

Need the following configurable settings:

Temperature Units F/C

Altitude (SCD30 setting)

Calibration (SCD30 setting)

Adjust Temperature Offset (SCD30 setting)

Adjust display Brightness

Update Interval setting

Needs to support OTA update
