I have Hass running on an RPi3 at home, not doing much at the moment though.

Hardware

RPi3 type B

Software

I'm running Hass.io because it's easymode.

Beaconing

General notes: https://www.home-assistant.io/blog/2016/04/30/ibeacons-part-1-making-presence-detection-work-better/

So it can do some interesting things, but it's especially good for presence detection and the like.

There's a bunch of libraries for supporting it in various forms, etc:

get things setup with dietpi-config, static IP, disable bootwait for network, ondemand power governor for 40sec

apt install less strace vim bluez-hcidump net-tools tcpdump lsof

copy tile-scan over, it should now run

try installing node-red via dietpi-software

deps for node-red-contrib-noble

• - libbluetooth-dev - libudev-dev

use the *ansson11 one, it's updated sorta-kinda

{ .trigger_source: "ble_tile1"; }

Doing setcap on /usr/local/bin/node seems to have fixed my woes, it wasn't screwed up npm packages after all (or maybe it is)

  212  npm install @abandonware/bluetooth-hci-socket
  213  npm install bluetooth-hci-socket@npm:@abandonware/bluetooth-hci-socket
  214  ls
  215  npm install @abandonware/noble
  216  npm install bluetooth-hci-socket@npm:@abandonware/bluetooth-hci-socket @abandonware/noble
