Issue with nRFConnect desktop App

[GK]

HI.

I am following the document http://infocenter.nordicsemi.com/pdf/nRFConnect_BLE_User_Guide_v2.2.pdf  to work with nRFConnect desktop App and my DK BMD300(Rigado).

I have flashed a program using nRFGoStudio already to the device ( SDK 15, Softdevice 132,PCA10040.

I opened the BLE App from nRFConnect.

Then I connected the DK through USB to laptop. It shows the following mesage.

"Device must be programmed, do you want to proceed".

If I give No, then everything is cancelled and it will be in the intial state.

If I give 'yes' then I think something  overwrites the previous program( I dont know what it is). 

Everything is displayed ( the discovered devices etc), but I think some unwanted program is running in the device.

Please guide me in solving this issue.

Thanking you.

with regards,

Geetha

Hi,

nRF Connect requires one device to use as a "connectivity device". What this means is that you use an nRF Dongle or DK connected to the PC, that provides BLE capabilities for nRF Connect.

This means you need another nRF device in addition to your custom application one.

Having your device with a custom BLE application connected to the PC is not a problem, just select the device that you want to use for connectivity device in the dropdown menu and everything should be fine.

So where to connect the other dongle. I mean it will require power to turn on right. So should I connect the other dongle to another PC? Or should I connect the other dongle to same PC?

Hi,

You can connect it to the same PC.

nRF Connect for Desktop will ask for downloading the connectivity firmware to an nRF device when you select it in the dropdown. Just make sure to select the correct device there, and you should be fine.

If you still experience problems, please take a screenshot of the error message and attach it here.

But after flashing the hex file to the dongle, the Led on the dongle stops glowing. That is it stops advertising and I cannot select the device from dropdown.
