	The ESP32 supports bluetooth as an RF technology. It would be nice to be able to quickly see the current/most recently measured data. This can be shown on the display. Perhaps even more convenient, this can be exposed over bluetooth for display on a mobile phone. Are there android apps that can interface with bluetooth?
