How to connect NRF52840 BLE in a desktop app?

[zain248]

I am very new to the Embedded world and very confused about some stuff, I have searched the internet for 8 hours and then asked here.

I am being assigned to the task of searching the internet for the source code to make nRF52840 connect with the Desktop App.

I just want to be guided about how can I connect a Desktop based app to the BLE of nRF52840, App is already being developed, I have searched that using 'pc-ble-driver' I can connect the BLE device with my app, is it true? or where should I look?

What I want to achieve is that, get the nRF to send some parameters like strings, etc to the desktop app, which will be on PC, with Bluetooth 4.0 or higher model.

Please suggest me a path to follow, I will do the hard work on my own but I am not going anywhere when I don't even know where to look.

Check out the app and source code by Microsoft here:

Then you can use the native BLE in the desktop to connect to a peer device such as nRF52840.

In terms of what firmware to program to the nRF52840 that will depend on what application you want to develop, but a good starting point may be the simple BLE blinky or nRF UART examples:

Note that if you need to support bonding I recommend to check out the heart rate sensor example:
