如何知道cordova中的蓝牙设备类型

Question

I am using a cordova plugin to display the list of all bluetooth device . But I need to filter out all the devices which are printer. How can I do so ? Is there anyway I can find the bluetooth device type by their mac address or name ?

Answer 1

As given in the documentation you mentioned.

var device_names = {};
var updateDeviceName = function (device) {
    device_names[device.address] = device.name;
};

// Add listener to receive newly found devices
networking.bluetooth.onDeviceAdded.addListener(updateDeviceName);

// With the listener in place, get the list of known devices
networking.bluetooth.getDevices(function (devices) {
    for (var i = 0; i < devices.length; i++) {
        updateDeviceName(devices[i]);
    }
});

// Now begin the discovery process.
networking.bluetooth.startDiscovery(function () {
    // Stop discovery after 30 seconds.
    setTimeout(function () {
        networking.bluetooth.stopDiscovery();
    }, 30000);
});
