Thank you very much, I have been struggling on this for weeks.

Okay, thank you for clarifying! Most of our example projects have a peripheral project and a corresponding central project. These centrals are usually set up to scan for devices running the peripheral project with the same name, and connect/pair to it either automatically when found or by pressing a button on the DK. You want the DK to act as the central running the ble_app_uart_c example and the Dongle to act as a peripheral by modifying the usbd_ble_uart example, correct?

If you check out the scan_init() function in the ble_app_uart_c example project, you can see that it sets scan filters that makes it only scan and detect devices with a specific UUID, so you'll have to either change the scan init to be able to scan for the usbd_ble_uart example, or change the peripheral device to advertise with the Nordic UART Service UUID which it scans for.

In order to pair the devices once connected, you will also have to implement the peer manager to set up and trig a pairing process between the two, as the ble_app_uart_c example does not support pairing by default. You can use the ble_app_hrs_c example for reference on this.

Best regards,

Sorry i think that my question was not clear.

What i want to do is to pair the nrf52840 dk with the nrf52840 dongle without the nrf connect app.

I know it is possible since someone already asked for that (here is the link to the Q/A https://devzone.nordicsemi.com/f/nordic-q-a/59030/pairing-nrf52840-dongle-with-nrf52840-dk) but i do not know the change I have to make to the examples for the nrf52840 dk communicate with the nrf52840 dongle and not with the mobile app.

Again sorry for the confusion.

Best regards,

Luca

Hi Luca

The process of modifying an nRF52840-DK (PCA10056) project to an nRF52840 Dongle (PCA10059) project, you can check out our Dongle Programming tutorial, which provides all the necessary steps to modify a project to fit the Dongle.

Best regards,

Simon
