WebBluetooth class
This is just a basic Class to start playing with the new Web Bluetooth API, specifications can change at any time so keep in mind that all of this is mostly experimental! ;)
Requirements
Check your browser and platform implementation status first.
Usage
Services and Characteristics JSON structure.
let services = {
'00000000-0000-0000-0000-000000000000' : { // service ID
name : 'Service 1',
characteristics : {
'00000000-0000-0000-0000-000000000000' : { // characteristic ID
name : "Characteristic 1"
},
"00000000-0000-0000-0000-000000000000" : {
name : "Characteristic 2"
},
...
}
},
...
}
let options = {
filters: [{
namePrefix: ['DeviceName']
}],
optionalServices: Object.keys(services) // array automatically generated from the services keys
};
With this simple command the Web Bluetooth API is called and the device discovery popup will appear.
WebBluetooth.connect( options, services )
.then( ()=>{
// device is connected
} );
Disconnects the device.
WebBluetooth.disconnect()
.then( ()=>{
// device is disconnected
} );
Read a value from a characteristic.
WebBluetooth.readCharacteristicValue( characteristicUuid )
.then( value => {
// the value has been read
console.log( value );
} );
Write a value into a characteristic.
WebBluetooth.writeCharacteristicValue( characteristicUuid )
.then( () => {
// the value has been written
} );
