Describe the bug
On Chrome 113, the callback is never called

To Reproduce

await BleClient.requestLEScan(
    {
        namePrefix: 'MY_PREFIX'
    },
    (result: ScanResult) => {
        console.log(result)
    }
);

Plugin version:

  • @capacitor-community/bluetooth-le: 3.0.0

Desktop (please complete the following information):

  • OS: Windows and Linux at least
  • Browser Chrome at least
  • Version 113.0.5672.126

Smartphone (please complete the following information):
No affected

Additional context
As mentioned here reelyactive/web-ble-demo#2, the usage of requestLEScan seems to be deprecated in favour of requestDevice

Thank you for the issue.

Unfortunately, requestLEScan is still an experimental feature and has never really been stable in Chrome (nor any other browser).

I'm not sure if there is anything that can be done about it in this plugin. If you're targeting the web platform, I would suggest to use requestDevice.

Hi @pwespi, thank you for the quick reply.

Yes, maybe I have overthink about this, and the docs indeed indicate that requestLEScan is unstable for web
