Subscribe to notifications from BLE device? #14

Closed ketile closed 8 years ago

ketile commented 8 years ago

Can't find any documentation on subscribing and unsubscribing to notifications using platinum-bluetooth. Is this possible or planned for implementation? Have not yet tried with the vanilla Web Bluetooth API but it seems possible.

Need this functionality for a demo and wondering if I should use Web Bluetooth API directly or through Polymer.

It is not yet implemented in platinum-bluetooth. I'm waiting for notifications to land in stable channel to update platinum-bluetooth.

You may want to use Web Bluetooth API instead for the moment and make sure you use a recent Chromium build on Android (https://download-chromium.appspot.com/?platform=Android).

See https://googlechrome.github.io/samples/web-bluetooth/notifications.html for how it works.

You should be able to combine the Polymer elements with the lower-level JS API. Right now, the BluetoothGATTCharacteristic you need is only exposed as <bluetooth-gatt-characteristic>._characteristic, but I think we should make that public so folks can fill in holes like this.
