Installation of Firmware

Normally, this firmware is uploaded to a DataLogger via the SD card or OTA - just using the 01.00.02.bin firmware file.

To install this firmware, as the main factory partition firmware for the DataLogger, use the following command.
Attached firmware binaries are uploaded using the following command/esptool settings (adjust port/baud for your device):

esptool.py --chip esp32 --port [YOUR PORT] --baud 460800 --before default_reset --after hard_reset write_flash  \
                 -z --flash_mode dio --flash_freq 80m --flash_size 16MB \
