Starting up BLE

[RH823]

Hi everyone, 

I am new to the development and I am trying to connect my nRF52480 to my phone. When I open the desktop app for BLE connections, I cannot select the start scanning icon. I am also getting this message: 

Installed JLink version does not match the provided version (V7.58b)

I downloaded the SEGGER/J-Link and the desktop apps through the Nordic Semiconductor website, so I am not sure why they are not working. 

Thanks in advance.

Hello,

Which version of the nRF Connect for desktop application are you using?
Could you confirm that you have selected a device to be used with the nRF Connect for desktop application, in the top left corner of the BLE application window? The menu reads 'Select Device'.
The nRF Connect for desktop application will require that you have a separate DK / Dongle that can function as the connectivity device for the application.

If you only have a single DK that you would like to connect to and test you could instead use the nRF Connect application for smartphones, which will let you do this without a separate connectivity device.

Best regards,
Karl

Hi, 

I am using the 3.12.1 version for the desktop application. I am able to connect to the device using the USB cord. After selecting the device, I am connected, however, I cannot select the option to start scanning for the bluetooth.

What does the full log say, after you select the device in the dropdown menu? Are you prompted to install the necessary firmware to the device, when you select it from the dropdown menu?

Could you also confirm whether you are working with a nRF52840 DK or dongle?

Best regards,
Karl

Getting information from J-Link debugger...

Found device type: unknown. J-Link firmware: J-Link OB-nRF5340-NordicSemi compiled Dec 3 2021 15:46:49.

The log above is the full log that I get. I am using the  nRF52840 DK.

Hello again,

Are you using MacOS or Linux? If so, you must disable MSD as detailed in the log.

Other than that, the log looks correct, and it seems to be able to find the device just fine.

Does the kit light up when you select it? Does the debugger led flash?
Could you try to uninstall and re-install the Bluetooth Low Energy application in nRF Connect for Desktop, and see if the behavior changes?

Best regards,
Karl
