Mi Band Demo NotFoundError

[lkalneus]

Hi! I've tried mi band demo, but got an error "NotFoundError: Service not found in device."

Should I turn something on the device first before a try?

Which OS do you run?
See https://github.com/WebBluetoothCG/web-bluetooth/blob/gh-pages/implementation-status.md#chrome

[lkalneus]

Android 5.1.1 (OxygenOS 2.1.4, the device is Oneplus one).
Also, I use Chromium 53.0.2754

[beaufortfrancois]

Let's figure out which one(s) is not found first ;)
Can you open the JS console (from about:inspect) and copy/paste these commands after trying to connect to it?

miband.server.getPrimaryService(0xFEE0).then(s => console.log('MIBAND_SERVICE'));
miband.server.getPrimaryService(0xFEE7).then(s => console.log('IOS_SERVICE'));

Well, the second one is failed.

Can you now install the nRF Master Control Panel Android app, scan for your MiBand device, connect to it and share found services?

[beaufortfrancois]

Do you have more services?
If not, do you know which firmware version of the MiBand device you're running?
Does your device work with the official Mi Fit app?

[beaufortfrancois]

Oh! I wonder if it's because it is not the same model as well.
I've only tried this demo with my Mi Band device: http://www.amazon.com/gp/product/B00RMO0T5I

[lkalneus]

No, that's all. Yes it works with Mi Fit app. The firmware version is 4.16.3.7. Heart rate firmware version is 1.3.76.18

So, looks like there is no way for me to make this demo?

You may want to try to remove

sandbox/web-bluetooth/mi-band/miBand.js

Lines 65 to 67 in 0f73ae8

	server.getPrimaryService(IOS_SERVICE_UUID).then(service => {
	return this._cacheCharacteristic(service, MAC_ADDRESS_UUID);
	}),

but even so, I think you need at some point to "pair" the device and you'll need the MAC Address for this IIRC ;(
