BLE Advertising, a beginner's tutorial : can't find device...

[Geoffroy]

hi, thanks for this tutorial : devzone.nordicsemi.com/.../ble-advertising-a-beginners-tutorial

i'm trying it on my nRF52840 devkit board.testing it with nRF connect application for android

i use SDK V15.0.0

I build the project and then i erased, program softdevice, program example-advertising then reset.

All this worked fine but then on nRF connect application for android i refresh/scan and i can't find "hello world" BLE device ... can someone help me pls ?

I could solve the problem :

"By default, the BL654 uses the nRF52840’s on-chip RC oscillator as its clock source, as opposed to the nRF52840 development kits which use an external crystal"

so i changed values in nrf_sdh.c so that it uses BL654 configuration...

Hello Geoffroy,

What values exactly did you change in nrf_sdh.c and what did you change them to?
