## Notes on the development environment
* start dev environment using `startDevEnv.sh`
* inside the container go into the directory `~/project`
* set the env variable `ARDUINO_SKETCHBOOK_DIR` to `$PWD`
* build application in container in directory `~/project` using `arduino-cli compile --fqbn=Heltec-esp32:esp32:WIFI_LoRa_32_V3 --export-binaries /home/arduino/project/sketch/`
* flash device using `esptool.py --port /dev/tty.usbserial-0001 --baud 921600 --chip esp32s3 write_flash --flash_mode dio --flash_size 8MB 0x0 sketch.ino.bootloader.bin 0x8000 sketch.ino.partitions.bin 0x10000 sketch.ino.bin`
