Support for BLE Extended Advertising

[anon-ware]

Some newer BLE devices that use Extended Advertising (Bluetooth 5.0+) are not detected during scanning in the app.

In particular, target devices implementing the Nordic UART Service (NUS) over extended advertising are not discovered, even though they are visible with other BLE scanning tools such as nRF Connect.

This suggests the current scanning implementation may be limited to legacy advertising packets. Adding support for Extended Advertising would improve compatibility with newer devices using NUS and similar services.

Please let me know if logs, device details, or testing would be helpful.

Looks like it is mainly an issue of providing the right flags during scan.
Can you recommend a test device?

I'm using custom firmware on a Silicon Labs chip which is how i found the issue, but i have also tested with an nRF52840DK using the "Bluetooth Extended Advertising Advertiser" example, which may be easier for you to replicate on a number of Nordic devices.
