    node-red-node-physical-web

    Nodes to allow Node-RED to act as an Eddystone BLE beacon.

    Prerequisites

    You will need a suitable Bluetooth Low Energy (BLE) stack and drivers for your hardware

    • for example Bluez 5.2.x or better.

    Raspberry Pi

    Install Bluetooth drivers and bluez stack, and set executeable by non-root user

    sudo apt-get install libbluetooth-dev libudev-dev pi-bluetooth
    sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)
    

    Linux / OSX / Windows

    Follow just the pre-reqs for noble here.

    Install

    Run the following command in your Node-RED user directory - typically ~/.node-red

    npm i node-red-node-physical-web
    

    Then on Linux follow these instructions:

    Usage

    Physical-Web Out

    A node to allow Node-RED to act as an Eddystone beacon broadcasting URLs

    The config window lets you set the initial URL, announcement power and period for the Eddystone.

    Any messages received will update the advertised URL from the msg.payload

    Physical-Web In

    A node to scan for local Eddystones and output information about discovered URLs and TLM data.

    Two types of messages will be emitted:

    • URL

      • type - Eddystone type
      • txPower - Received power at 0m in dBm
      • url - The URL the beacon is broadcasting
      • tlm - TLM data, if the device is interleaving broadcasts
      • rssi - RSSI of the beacon
      • distance - Estimated distance to the beacon
    • UID

      • type - Eddystone type
      • txPower - Received power at 0m in dBm
      • namespace - 10-byte ID of namespace
      • instance - 6-byte ID instance
      • tlm - TLM data, if the device is interleaving broadcasts
      • rssi - RSSI of the beacon
      • distance - Estimated distance to the beacon

    Where the tlm data will be in the following format

    • tlm
      • version - TLM version
      • vbatt - Battery Voltage
      • temp - Temperature
      • advCnt - Advertising PDU count
      • secCnt - Time since power on or reboot
      • rssi - RSSI of the beacon
      • distance - Estimated distance to the beacon

    Install

    npm i node-red-node-physical-web
