Nordic Thingy:52 for Web Bluetooth

About Thingy:52

The Nordic Thingy:52™ is a compact, power-optimized, multi-sensor development kit. It is an easy-to-use development platform, designed to help you build IoT prototypes and demos, without the need to build hardware or write firmware. Read more about it here.

This repository

This repository is an attempt to make it easier to start developing applications for Thingy:52 using Web Bluetooth. Web Bluetooth is a JavaScript API that makes it possible to communicate with Bluetooth Low Energy devices in web browsers. The implementation status for different browsers and platforms can be seen here.

This is work in progress, and for now this repository will help you connect to a Thingy:52 and access all services and characteristics except for MTU (Maximum Transmission Unit):

Get started

Clone or download this repository.
If you've used this repository, you can serve index.html using any http server. You can then navigate to the server address in a supported browser and open the console (ctrl + shift + J or cmd + alt + J).
Turn on your Thingy:52.
Click the "Connect" button found on the page.
You can now choose your Thingy:52 and connect to it.
In the console, you can see the browser connect to the device and discover its services.
When connected, the Thingy:52 will use the LED breathe feature and the LED will pulsate with a RED light.
In the browser, it will also show the current temperature measured by the device in the HTML element below the connect button.

Examples

The following example will first connect to a thingy:52 with the option logEnabled set to false, then subscribe to and log all incoming data from the temperature sensor. After that we will request the device's name, before setting it to "Thingy". In the end, we set a timeout for 10 secounds before we disconnect from the device.

import Thingy from "./js/thingy.js";

const thingy = new Thingy({logEnabled: false});

function myLoggingFunction(data) {
    const temperatureData = data.detail;
    console.log(temperatureData);
}

async function start(device) {
    try {
        await device.connect();
        
        device.addEventListener("temperature", myLoggingFunction);
        await device.temperature.start();
        
        const deviceName = await device.name.read();
        console.log(deviceName);

        await device.name.write("Thingy");

        setTimeout(async () => {
        await device.disconnect();
        console.log("Disconnected from the device");
        }, 10000);
        
    } catch (error) {
        console.error(error);
    }
}

start(thingy);

The following example will first connect to a thingy:52, and then read the current LED configuration. In the end we will set the LED to breathe mode, with an intensity of 50% and a delay of 1 second.

import Thingy from "./js/thingy.js";

const thingy = new Thingy();

async function start(device) {
    try {
        await device.connect();

        const currentLedConfiguration = await device.led.read();
        console.log(currentLedConfiguration);
        
        const newLedConfiguration = {
            mode: "breathe",
            color: "cyan",
            intensity: 50,
            delay: 1000,
        }
        
        await device.led.write(newLedConfiguration);  
    } catch (error) {
        console.error(error);
    }
}

start(thingy);

Note: the Web Bluetooth API requires that a function trying to connect to a BLE device is initiated by a user action such as a mouse click.

API documentation

Thingy offers several features, all of which rely on established BLE protocols for sending and receiving data. The BLE operations are abstracted away through the following operations:

Operation	Description
start/stop	Subscribes to a feature and relays any incoming data from that feature as an event to the device object.
read	Reads data from the specified feature on Thingy.
write	Writes data to the specified feature on Thingy.

Note: If any connect/start/stop operation is unsuccessful due to network congestion, the method is queued and and re-tried at a later time. If the operation continues to complete unsuccessfully, an event will be dispatched on thingy.operationdiscarded.

Event	Description
thingy.error	An event with this name is emitted on any and all errors. The event contains information about the error, as well as the feature and operation that caused the error to occur.
thingy.operationdiscarded	An event with this name is emitted whenever a connect/start/stop operation is discarded on one of Thingy's features. The event contains information about the operation that was cancelled along with a function call.
thingy.write	An event with this name is emitted whenever a successful write operation has been performed. The event contains information about the feature that triggered the write operation, as well as the value that written.
