Can't find peripherals that implement extended advertising

[BikeBr0]

Describe the bug
Since our peripheral switched to using extended advertising, I have not been able to find the peripheral when performing a scan. It was previously working when the peripheral used standard advertising.

To Reproduce
Steps to reproduce the behavior:

1. Scan for peripherals that implement extended advertising _ble.scanForDevices(withServices: withServices)

Expected behavior
To find the peripheral

Smartphone / tablet

• Google Pixel 6 (Android 12)
• Google Nexus 6P (Android 8.1.0)
• flutter_reactive_ble: ^5.0.2
• Flutter version 3.0.1
• Dart version 2.17.1

Peripheral device

• nRF52840-DK
• Does it run a custom firmware / software: yes

Additional context
This is an android specific bug as both advertising models work on iOS. Also, peripherals using extended advertising do appear in the scan results of the nRF Connect App on the Android Pixel 6.

Further to the information provided above, we have tried using sample firmware provided with the nRF52840-DK and configured it to use Bluetooth 5 Advertising Extension. The peripheral shows up on nRF Connect on the Google Pixel 6 but not in my custom Flutter App. Is this not supported by flutter_reactive_ble?

Im having the same problem. It seems RxAndroidBle does not support extended advertising yet (dariuszseweryn/RxAndroidBle#774 )

Soon RxAndroidBle will support extended advertising! Check the PR:
dariuszseweryn/RxAndroidBle#801

Here is the change flutter_reactive_ble will need:

@Taym95 is there any ETA for a release with the fix?

[Taym95]

@danielstuart14, I will make new release

[danielstuart14]

Any news about that?

Would be great if this issue can be opened again, until a new release is out.
