Extended Advertising with SDK 15.1 seems not to work

[PeterLeicht]

I have tried out the Running Speed and Cadence Application of SDK 15.1 with the new DK "PCA 10056" (1.0.0, 2018.19, 683681562). We used the Samsung S8 and S9 with Android Oreo. But with the activated extended advertisement we cannot find the running application listed on the app "nrf Connect". 

Only when we set the variable init.config.ble_adv_extended_enabled to false, the we can see the running app listed, but then with the shortened advertising name: "nRF Running Sp".

The firmware uses following softdevice: s140_nrf52_6.1.0_softdevice.hex

What is the problem here? Even with Samsung Galaxy S9 with Oreo we cannot list the extended advertised name of the application.

Thanks for your answers.

Hi PeterLeicht.

I have the same issue with Samsung Galaxy S8 with Android 8.0 Oreo and Xiaomi Redmi Note 5 (both of them with Bluetooth 5).

I think I know the reason of this: If I open nRF Connect app and open the menu -> Device information, the following info is shown:

Extended advertisement supported: NO. 

Maximum advertising data length: 31.

I read in some place that manufacturers can say that their smartphones is Bluetooth 5 compatible just with High speed (PHY 2M) support. It's not necessary Long Range, Periodic advertisement or Extended Advertisement support. In my opinion, this is unfair.

I'm just looking for some way to sniff extended advertisement with another PCA 10056 (some example in the SDK could be perfect). If you know how to do, i will be greatful.

Sincerely,
