This flow (and associated circuits/hardware) is designed to allow Node-RED to pass messages via radio waves in the same way as it passes messages via MQTT, using commonly-available, inexpensive handheld radios and the Raspberry Pi. The flow has been tested using Baofeng, Wouxun, and Quansheng handheld ham radios. In short, the goal is to allow packet-like transmissions between Node-RED systems over miles, while keeping the hardware costs down (or free for those hams who have surplus Baofengs hanging around). This could be used for a backup to MQTT when the Wifi is unreliable, or simply as a long-distance and network-agnostic message channel.

Prerequisites: Software

First, we need PulseAudio to make and receive sounds with our USB soundcard:

sudo apt-get install pulseaudio -y

	ddns-update-style none;
	deny bootp; #default
	authoritative;

	include "/etc/dhcp/ipxe-option-space.conf";

	# GREEN (private network)
	subnet 10.1.1.0 netmask 255.255.255.0 {
	range 10.1.1.100 10.1.1.199;
	option subnet-mask 255.255.255.0;

	import uuid
	import wtforms_json
	from sqlalchemy import not_
	from sqlalchemy.dialects.postgresql import UUID
	from wtforms import Form
	from wtforms.fields import FormField, FieldList
	from wtforms.validators import Length

	from flask import current_app as app
	from flask import request, json, jsonify, abort
