Force-Sensing Climbing Training

The objective of this project is to create a Web Bluetooth API client that can establish connections with various Force-Sensing Hangboards / Dynamometers / Plates / LED system boards used by climbers. Examples of such tools include the Griptonite Motherboard, Tindeq Progressor, PitchSix Force Board, Weiheng WH-C06, Frez Dyno, Forma DUE, Entralpi, Climbro, or mySmartBoard

And LED system boards from Aurora Climbing like the Kilter Board, Tension Board, Grasshopper Board, Decoy Board, Touchstone Board and So iLL Board.

And gyroscopic hand exercisers, such as the NSD PB-700BT.

The library is available in multiple flavors to support different platforms:

• Web: The core package for web applications using the Web Bluetooth API
• Capacitor: For hybrid mobile apps using Capacitor
• React Native: For native mobile apps using React Native
• CLI: Command-line tools for device management and data analysis

The packages are available on both NPM and JSR.

# For Web applications
$ npm install @hangtime/grip-connect

# For Capacitor hybrid mobile apps
$ npm install @hangtime/grip-connect-capacitor

# For React Native mobile apps
$ npm install @hangtime/grip-connect-react-native

# For Node.js, Bun, Deno CLI tools
$ npm install @hangtime/grip-connect-cli
$ bun add @hangtime/grip-connect-cli
$ deno add @hangtime/grip-connect-cli

Simply importing the device you need from @hangtime/grip-connect.

<button id="motherboard" type="button">Connect Motherboard</button>

import { Motherboard } from "@hangtime/grip-connect"

// Initiate device
const motherboard = new Motherboard()

// Optional: Custom data handler
motherboard.notify((data) => {
  // { massTotal: "0", massMax: "0", massAverage: "0", massLeft: "0", massCenter: "0", massRight: "0" }
  console.log(data)
})

// Optional: Check if the device is active
motherboard.active(
  (isActive) => {
    console.log(isActive)
  },
  // Optionally using a weight threshold and duration
  { threshold: 2.5, duration: 1000 },
)

document.querySelector("#motherboard").addEventListener("click", async () => {
  // Connect to device
  await motherboard.connect(
    async () => {
      // Example: Read device specific data
      const batteryLevel = await motherboard.battery()
      console.log(batteryLevel)

      // LEDs: "green", "red", "orange", or no argument to turn off
      // await motherboard.led("red")
      // await motherboard.led()

      // Start weight streaming (for 30s) remove parameter for a continues stream
      await motherboard.stream(30000)

      // Manualy tare the device when the stream is running
      // await motherboard.tare(5000)

      // Manually call stop method if stream is continues
      // await motherboard.stop()

      // Download data as CSV, JSON, or XML (default: CSV) format => timestamp, frame, battery, samples, masses
      // await motherboard.download('json')

      // Optionally disconnect from device after we are done
      motherboard.disconnect()
    },
    (error) => {
      // Optinal custom error handeling
      console.error(error.message)
    },
  )
})

All devices provide some default features such as connect, isConnected, and disconnect. Additionally, each device offers specific features—refer to the documentation for more details on individual devices. There are also extra features that are not part of the device itself, like a reactive isActive check and a download feature.

Help wanted: Do you own any of the missing devices? Use Google Chrome's Bluetooth Internals chrome://bluetooth-internals/#devices and press Start Scan to look for your device, click on Inspect and share all available services with us.
