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.

Thank you Manuel, this truely helps me, so I know the problem is most certainly on our mobile devices, because the Samsung S8 and S9 show that they only support High Speed from the BT 5 features.
