It says something about programming it using a J-Link (which I do have) and SWD, but then launches off into a discussion about voltages, and I see nowhere to connect SWD anyway. Have I somehow 'bricked' this device, and if so, is there a way of getting it back? I already tried reading the other posts with similar subjects and also this and I am not familiar enough with Nordic terminology to find that much help. Now pressing the reset button on the board does nothing and the LED remains out. All the controls under Device are greyed out. The right hand one shows a green block in the bottom. The left hand pane on the main Programmer window says 'Unknown' and is greyed out. Now the device does appear in Windows Device Manager as a Virtual Com Port, and Programmer recognises it as 'RF Sniffer for Bluetooth' but says this message when starting up if the dongle is connected:Įrror when fetching device versions: readFwInfo error This seemed to work except that after seemingly programming the firmware okay it did display an error message which due to unfamiliarity with the Programmer 2.0.1 I did not realise needed to be saved. I tried to follow the lengthy installation instructions on the Nordic web site to load versious software, download firmware for the dongle and configure WireShark, etc. I do not have any prior experience with Nordic products but I have developed several BLE systems using Silabs and Infineon SoCs.

a 'completion' or an 'error', issed after the data transfer completion.I have bought the nRF52840 to use it as a BLE Sniffer.

a 'submit', issued when the USB data transfer begins.

For each captured 'packet' (URB, using the USB terminology) the kernel (and thus libpcap) provides two 'events': In the current implementation the data link type is DLT_USB_LINUX (189). In a preliminary version of the libpcap support for USB sniffing, USB buses were listed as 'interfaces' with a data link type of DLT_USB (186). See CaptureSetup/USB for information on this. The current cvs version of libpcap (9 October 2006) supports sniffing from USB ports, at least for the Linux platform with the 2.6.9 and later kernels with the usbmon infrastructure.
