windows does not recognize the sniffer

[Gil]

Hi,

I am trying to use nRF52832 evaluation board as a BLE sniffer. I have windows 7.

I installed nRFgo studio and downloaded nRF Sniffer v1.0.1.

I plugged the board into USB and it appeared as COM10 and ran ble-sniffer_win_1.0.1_1111_Sniffer.exe file

It seems like the application does not recognize my board.

Please help.

Hi, that software is quite old now. Can you try the newest version of the sniffer (v 2.1) ? The user guide is located here: https://infocenter.nordicsemi.com/pdf/nRF_Sniffer_UG_v2.1.pdf?cp=6_4_0

And the software can be downloaded here: http://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Sniffer/Download#infotabs

OK. I'll try it out.

OK. I got to the stage  Install firmware with SEGGER J-Link (nRF Sniffer User Guide v2.1) and when i tried to call the hex file (which is in my case exists in: C:\Program Files\Wireshark\extcap\hex\sniffer_pca10040_1c2a221.hex)

Using this command at the cmd prompt (as administrator):

J-Link> loadfile C:\Program Files\Wireshark\extcap\hex\sniffer_pca10040_1c2a221.hex

I get the following error:

Downloading file [C:\Program]...

File is of unknown / supported format.

Any ideas about that?

Hi, try to use nrfjprog instead to flash the chip: https://infocenter.nordicsemi.com/topic/ug_nrf5x_cltools/UG/cltools/nrf5x_command_line_tools_lpage.html?cp=6_1

Not sure why they tell you to use JLink.exe in the user guide, we always just use nrfjprog. Maybe it's because nrfjprog is bundled with a newer version of the jlink driver. I think the sniffer needs a specific version of jlink to work. I think this is covered in the "Verify that Jlink emulator firmware is correct version" section of the user guide.

It.worked. The nrfjprog program needed to have the hex file at the same folder as the nrfjprog.exe file

Thanks
