No services matching UUID help

[Cegard]

Hello Everyone:

I've been playing around with WebBluetooth since a couple of days ago, for that I've been using my phone with the nRF Connect app as a GATT Server, and I've been using the next function to attempt the connection with the phone:

		async function onButtonClick() {
			let device = await navigator.bluetooth.requestDevice({
				acceptAllDevices: true,
				optionalServices: [ 0x180D ]
			});
			let server = await device.gatt.connect();
			console.log(server);
			let service = await server.getPrimaryService(0x180D);
			console.log(service);
		}

I've been trying the services: 0x181C, health_monitor, heart_rate, but the result I'm getting is: DOMException: No Services matching UUID 000180-0000-1000-8000-00805f9b34fb; and with the service "0000aaa0-0000-1000-8000-aabbccddeeff" I get DOMException: Origin is not allowed to access the service. Tip: Add the service UUID to 'optionalServices' in requestDevice() options.

Any ideas of what could be happening, or another way to test this?

Thanks in advance.

To be able to access the services, you need to specify them in the filters property of the RequestDeviceOptions or in optionalServices. In your example, you're using acceptAllDevices: true, so you'll need to add the services that you want to access to optionalServices in order to get permission to access them.

Hello again:

I managed to get to the service (and to the characteristic after that), the solution was adding another service in the optionalServices field and then ask for just one of them with server.getPrimaryService, something like this:

		async function onButtonClick() {
			let device = await navigator.bluetooth.requestDevice({
				acceptAllDevices: true,
				optionalServices: [0x1801, "162348d9-d5a8-4870-8086-8e152fd06a92"]
			});
			let server = await device.gatt.connect();
			console.log(server);
			let service = await server.getPrimaryService("162348d9-d5a8-4870-8086-8e152fd06a92");
			console.log("serviced");
			console.log(service);
		}	

If I only specify one of them in optionalServices and try to retrieve it, it won't work, is this the expected behavior?

**Edit: For this to suceed I had to use a custom bluetooth device (raspberry), when using nRF on my phone with the two services solution it just stays waiting for the connection, it doesn't show any message, just keeps waiting and waiting.

[odejesush]

Yes, if it's not specified, the site does not receive permission to access the service. This is intended behavior.

The same problem as the originator：
error：
DOMException: Origin is not allowed to access the service. Tip: Add the service UUID to 'optionalServices' in requestDevice() options.

It's been bothering me for a long time
Please help me.

navigator.bluetooth.requestDevice({
	 filters: [ 
        { namePrefix: 'play' } 
    ],
    optionalServices: [ "162348d9-d5a8-4870-8086-8e152fd06a92"]
}).then(device => {
	console.log('Got device:', device.name);
	return device.gatt.connect();
})
.then(server => {
	return server.getPrimaryService("162348d9-d5a8-4870-8086-8e152fd06a92");
})
.then(service => {
	
})
.then(characteristic => {

})
.then(value => {
	value = value.buffer ? value : new DataView(value);
	console.log('Battery percentage:', value.getUint8(0));
})
.catch(exception => {
	console.log(exception);
});

[Cegard]

Hey @zhangzhoufei, sorry for the delay, you could try to add another service (besides the one you need to access) in the optionalServices field, or deleting that field and use the getPrimaryServices function. For me both of these solitions are workarounds, but they worked for me.

i get the same error,this is my code:

            let device = await navigator.bluetooth.requestDevice({
                filters: [{
                    namePrefix: 'Pai',
                    // services: ['0000fff0-0000-1000-8000-00805f9b34fb','0000fff1-0000-1000-8000-00805f9b34fb','0000fff2-0000-1000-8000-00805f9b34fb','0000fff3-0000-1000-8000-00805f9b34fb'],
                    optionalServices: ['0000fff0-0000-1000-8000-00805f9b34fb']
                }]
            });
            console.log(1);
            console.log('Got device:', device.name);
            console.log('id:', device.id);
            let server = await device.gatt.connect();
            console.log(server);
            await delay(10000);
            console.log(2);
            let services = await server.getPrimaryService('0000fff0-0000-1000-8000-00805f9b34fb')
            console.log(3,services);
            let characteristic = await services.getCharacteristic('0000fff0-0000-1000-8000-00805f9b34fb');
            console.log(characteristic);

Any ideas of what could be happening, or another way to fix this?

Hi,
I am getting the same error message while trying to get the battery service (0x180F) of a Tacx Heart Rate Belt.
nRF Connect shows the service is there and can read it's Battery Level characteristic, but:

• in chrome://bluetooth-internals/ the service is missing,
• Also the code example at web bluetooth samples fails with the same error:

No Services matching UUID 0000180f-0000-1000-8000-00805f9b34fb found in Device.

Meanwhile I am able to successfully work with the Device Information Service (0x180A), and Heart Rate Service (0x180D).

Here is the log from nRF Connect:

@dvmarinoff, please file an issue on crbug.com for this problem and tag it with the Blink>Bluetooth complement. If you can please test on a macOS or Windows device as well.

I'm observing that chrome://bluetooth-internals only lists 8 of 10 available services. The missing services are battery_service 0x180f and generic_access 0x1800.
Both of these services appear on nRF Connect and via BlueZ CLI.

Turns out that a default BlueZ plugin was stealing battery_service 0x180f.
The fix is to disable the plugin with the -P battery flag. More details on the solution are described in WebBluetoothCG/ble-test-peripheral-android#95 (comment)

Now chrome successfully detects battery_service 0x180f 🎉

[travisghansen]

I ran into this issue when developing against a custom BLE service (service is running on another linux node). After adding characteristics to the service it seems that triggered this issue.

To resolve I have consistently been able to do the following (on the web bluetooth node):

rm -rf /var/lib/bluetooth/*
systemctl restart bluetooth.service
