nRF25840 + nRFConnectDesktop firmware setup not working

proff

Hi all

I just bought a nrf52840 to be able to work with nrfConnectDesktop BLE sniffer tool

I've plug the nRF52840 board using IMCU USB

when I try to select the device it finds the 52840 board

once selected it ask for a firmware update

firmware download looks a bit too quick and log goes like this

after firmware flash I have no data and if i try to reconnect it asks again for firmware flash

I think I have an issue with FW flash obviously but did'nt know what to try ...

I've try to plug board trough nrf52840 usb on side of board but it dont detect any device
when going trough nRF52840 getting started tutorial all leds pulsing correctly and switch are ok too

thank's for any help

    Hello,

    I notice you are mentioning two different things here: nRF Sniffer for BLE vs. nRF connect for Desktop BLE standalone app.

    They are not the same, so I am not entirely sure what you are trying to achieve here. But in any case, if you want to use the one of the other, make sure that you have closed down other software that may be using the com ports on your PC. You can try for instance do a restart and just open the nRF Connect for Desktop app for BLE if that is the one you want to use.

    You can also try to install the command line tools if you haven't already:
    https://www.nordicsemi.com/Products/Development-tools/nRF-Command-Line-Tools/Download 

    If you still have problems please specify exactly which hardware (e.g. nRF52840-DK v3.0.0 or similar) and software (e.g. nRF Connect for Desktop v4.4.1 or similar, nRF Command line tools v10.24.1 or similar).

    I'm using a nRF52840-DK

    sticker on board says :

    when I try to open ble tool from nrf connect desktop it opens bluetooth low enegy v 4.0.4 patch1 and its closes immediatly to open standalone v4.0.4

    in order to avoid error when opening

    I have c;lose all nrf app and tryc to start directly standalone ble tool I have same issue

    I have also try to uninstall standalone revision to stick to desktop suite only and it continue to close immediatly first window and opens standalone rev but window stays empty now

    nrf connect is rev 4.4.1

    in order to avoid any miss instalation I've wipe out nrfConnectDesktop and ble standalone tool
    reboot and reinstall freshly downloaded 4.4.1 nRfConnectDesktop but it same result first window close immediatly and standalone ble tool is oppen even if it's not installed =| !!
