Can't see Nordic_Prox in Devices

[cycledude]

I have just purchased a nRF52840-DK

I am following the getting started tutorial and when I scan for devices the Nordic_prox device is not appearing in the device list but other devices are.

I loaded the proximity demo .bin file in the JLINK folder on my PC.The proximity demo does not work as it does not see the Nordic_prox device.

I am using a windows 10 pc,and  a samsung s9 phone,with nRF Connect and nRF toolbox installed.

Can you please assist?

Regards

Hello Rick,

Where exactly did you find that .bin file? I suggest that you try to upload the .hex file that is located in the folder:

SDK\examples\ble_peripheral\ble_app_proximity\hex\ble_app_proximity_pca10056_s140.hex.

Note that this file is precompiled. If you change anything in this project, it will not affect this .hex file. 

If you change anything in the project, you need to build it, using e.g. Segger Embedded Studio. You can also flash your project using Segger Embedded Studio, and it will also upload the SoftDevice (Bluetooth Low Energy Stack) automatically. If you use another IDE, you must upload the softdevice manually from SDK\components\softdevice\s140\hex\*.hex

The precompiled hex files already has the softdevice merged into it. 

If you flash the correct files, you should see LED1 blink when it starts to advertise. If you can't see it from your phone, does the LED blink?

Also could you please suggest some resources on you site for beginners?
