titou4307

Is it possible to have an idea of solution ?

    Hello Claude,

    The errors indicate that there is a communication issue between your PC and the connectivity board/dongle, but I don't see any indication of what is causing it. Are you using the nRF52840 Dongle to test with?

    Best regards,

    Vidar

    Hello Vidar

    First many thanks for the first response

    this product is the Dongle Usb of Makerdiary....

    I don't know where is the problem....When I connect the dongle led passed to green (when I push the reset button...)

    After this It appear on usb to serial

    But impossible to access to this peripheral with nrfutil, adafruit-nrfutil and your software nrfconnect

    But after many and many test and more and more hours, after a change of the product of Makerdiary I have an issue with wizzard....

    When I reset the dongle (while connecting) the dongle pass green to red blink and after it return green

    Other try the led is green, I reset the dongle, the led pass in blank and so after in green

    I have reset by clicking the reset button and magic it appear in the nrfconnect

    With this soft I can scan BLE and pass on other app so the Nrfconnect ask to me flashing at each time .... I think it is the normal mode ??

    I would like to have this dongle into wireshark so I follow the tutorial in Elektor :

    https://www.elektormagazine.fr/magazine/elektor-275/61031

    With many try and many hours (night !!) impossible to change the bootloader...

    But one chance I succeed to flash the bootloader and normally the dongle must start and appear like USB key but nothing !!

    After research I found this link :

    https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_sniffer_ble%2FUG%2Fsniffer_ble%2Fintro.html

    It will OK at this time but I don't know why it function or not and why it impossible to enter in DFU mode (reset at connection) each time and not one time or one time....

    There is a solution to verify the flash, bootloarder and other parameter on this dongle ??

    I don't have this Makerdiary dongle here to test with, so I can tell if this is expected behavior or not, unfortunately. We only test nRF connect app with the following boards:

    (nRF Connect Bluetooth Low Energy)

    And the nRF sniffer:

    What Softdevice did you use, and how did you program it?

    What bootloader are you trying to flash, the UF2 or the open bootloader?

    Did you manage to load the sniffer FW .hex (sniffer_nrf52840dongle_nrf52840_4.1.0.hex) to your dongle?

    I have done many and many tests and try with nrfutil, adafruit-nrfutil and nrfconnect....So at this time my memory is in default ...sorry I not give to your all the tests and procedure

    I have follow the Elektor process without success...

    The Oem firmware if I not say error is openbootloader so I have try to pass in UF2 bootloader...

    And yes in final this is the firmware "sniffer_nrf52840dongle_nrf52840_4.1.0.hex" I use ....

    Thanks for the clarification. But I'm not sure if it really matters if you run the UF2 or open bootloader on the device as long as you are able upload the application image (i.e. sniffer_nrf52840dongle_nrf52840_4.1.0.hex or the connectivity hex).

    Are you able to upload 'sniffer_nrf52840dongle_nrf52840_4.1.0.hex' to the dongle without errors, and does it show up as a USB device afterwards?
