ESP32-based smart-nametag

[luposlip]

Instead of the standard, boring plastic-and-paper name tag, let's do something new and clever. Perhaps based on ESP32: http://esp32.net/

Found this fun little re-natal (React Native) + Bluetooth ESP32 control app: https://github.com/asukiaaa/re-natal-esp32control-app

I've previously used (slightly modified) MQTT firmware for H801 (esp8266), found here: https://github.com/open-homeautomation/h801/tree/master/mqtt The build chain works fine on Linux; use the (terrible) Arduino IDE the first time, enable debug logging and look at the output to get the commands used for building and flashing firmware.

A guide to flashing firmware on an H801 can be found here: https://anthonynet.org/2017/06/21/reflash-h801/

Ideas

• play with Ferret/Arduino to be able to write firmware for esp32/esp8266 from a Clojure-like language: https://nakkaya.com/2016/06/10/ferret-a-hard-real-time-clojure-for-lisp-machines/
  • use MQTT for server communication; light weight and standardized
• play with BLE with the goal of being able to detect another tag

I've ordered a few esp32 that I can bring to the next meetup, along with an I2C RFID reader, some accelerometers, humidity sensors, relays and whatever else I can find in my drawers.
