The Bluetooth.requestDevice() method of the Bluetooth interface returns a Promise to a BluetoothDevice object with the specified options. If there is no chooser UI, this method returns the first device matching the criteria.

Syntax

Returns

A Promise to a BluetoothDevice object.

Parameters

  • filters[]: An array of BluetoothScanFilters. This filter consists of an array of  BluetoothServiceUUIDs, a name parameter, and a namePrefix parameter.
  • optionalServices[]: An array of BluetoothServiceUUIDs.

Example

navigator.bluetooth.requestDevice(options).then(function(device) {
  console.log('Name: ' + device.name);
  // Do something with the device.
})
.catch(function(error) {
  console.log("Something went wrong. " + error);
});
