Get Started

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, 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.

Example usage (Motherboard)

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
      // motherboard.download('json')

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