Griptonite Motherboard, Tindeq Progressor, PitchSix Force Board, WHC-06, Entralpi, Climbro, mySmartBoard: Bluetooth API Force-Sensing strength analysis for climbers
npm install @hangtime/grip-connectForce-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, 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 split into platform-specific packages:
- 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
- Runtime: Adapter for Node.js, Bun, and Deno—script connections
- CLI: Ready to use Command-line tool to connect to devices

npm install @hangtime/grip-connect
Example usage (with a Motherboard)
Simply importing the device you need from
.`html
`js
import { Motherboard } from "@hangtime/grip-connect"// Initiate device
const motherboard = new Motherboard()
// Optional: Custom data handler. For pounds: device.notify((data) => {}, "lbs")
motherboard.notify((data) => {
// { unit, timestamp, current, peak, mean, distribution? }
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)
},
)
})

Smartboard Climbing - SmartBoard ProFeatures
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.Development
