NRF52840 Dongle using NRF Connect

Lewy2552

Hello, I have a couple of questions concerning the nrf52840 dongle

1. Is the dongle supported in the nrf connect sdk? I see that the board is within the build boards, but I noticed that when I put the device in bootloader mode, it does not appear.

2. Where is the code that is used for the NRF Connect for desktop BLE app? I noticed it flashes the dongle in order to use the app and was hoping to be able to modify my own version of it so that it only looks for my device

Thanks!

    Hi, 

    1. Is the dongle supported in the nrf connect sdk?

    Yes, see the Developing with nRF52 Series doc:

    I see that the board is within the build boards, but I noticed that when I put the device in bootloader mode, it does not appear.

    It's not clear to me. Where does it not appear? nRF BLE app? It will show as "Nordic Semiconductor Open bootloader" like the following figure with bootloader mode (Press the reset button to put the Dongle in DFU mode). 

    2. Where is the code that is used for the NRF Connect for desktop BLE app? I noticed it flashes the dongle in order to use the app and was hoping to be able to modify my own version of it so that it only looks for my device

    Here is the code https://github.com/NordicSemiconductor/pc-nrfconnect-ble Please be aware that nRF Connect BluetoothRegistered Low Energy helps you learn how to configure and test Bluetooth Low Energy devices. It's an assistant tool and not suitable for development. For development, you can refer to Bluetooth samples.

    Sorry for the confusion on this. What I meant was connected devices list on the nrf connect vs code extension. I dont have a problem with the dongle getting detected by the ble app.

    Thank you for this link, I have already gone through the bluetooth class nordic provides, so Ill start playing around with those example files!

    Since the nRF52840 dongle doesn't have an onboard debugger, it will not be shown in the VS Code. You need to use the nRF Programmer to flash the image. nRF52840 dongle is for prototyping, so I would suggest you use nRF52840DK including the onboard debugger for development.
