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"; }
