Good to know on the Coded PHY (helps us to manage expectations). Waiting on DK to show up.

I do not think that support for coded PHY is available in the nRF Sniffer. You do need the COM port which the nRF52840-DK exposes to get this to work correctly.

Wow! Thank you all for responses. We've ordered the 52840 DK as we need to a BLE sniffer that can detect Coded PHY packets which is why we ordered the 52833 DKs initially. Now just waiting for the 52840 DK to arrive.

Follow-on question. We are getting all the software downloaded (as outlined in Nordic instructions for the BLE Sniffer) to program the 52840 DK for when it arrives and encountered an error with the steps for ensuring the nRF Sniffer files runs correctly with Wireshark. Specifically, do we need to have the 52840 DK physically connected to our computer to ensure the Sniffer files run correctly? We get an error stating "serial not found" when we do the below but again we don't have the DK just yet.

I will add that to the ticket.

Although keep in mind that Windows 7 is officially deprecated.

BR,

Additionally the nRF52-Dongle will need some more work to get it to work on Windows 7 as the nRF Connect Desktop only supports the driver for Win 10 out of the box.

Edvin Can you also request addition of the Win 7 drivers in nRF Connect Desktop so we dont have to hand edit the inf files.

Hello,

as daviddedwin says, the nrf52840 .hex file doesn't work out of the box with the nRF52833 DK, unfortunately.

I'll create an internal ticket letting the developers know that there is currently no pca10100 .hex files, but I don't know when/if that will be published. I guess it depends on their worklog.

The nRF52840 DK works with the sniffer_nrf52840dk_nrf52840_7cc811f.hex file, but if you want a cheaper solution, you can now use the nRF52 Dongle with the sniffer_nrf52840dongle_nrf52840_7cc811f.hex file from nRF Sniffer for Bluetooth v3.1.0.

Note that the nRF52 dongle doesn't have an onboard debugger, so you need to use nRF Connect for Desktop to flash it (not a problem), but it makes it not great for application development. If you intend to do application development on the nRF52840, I would recommend an nRF52840 DK. If you need it just as a sniffer, or alternatively as a development tool with nRF Connect for Desktop, the dongle should work just fine!

Best regards,

Edvin

The Sniffer firmware for the nRF52840-DK and the nRF52832-DK worked as expected and wireshark was able to detect the sniffers.

Hey thanks so much. At least I won't waste time trying to figure out how to upload the Sniffer firmware on the 52833. Have you uploaded the Sniffer on the nRF52840 DK? If so then I'll just order that board.

Thanks again!

There does not seem to be a hex file that directly supports the nRF52833-DK in the nRFSniffer release. You could try the hex for the nRF52840-DK but I am not certain it would work as the RAM size for the 833 is less than the 840 but worth a try.
Try programming the hex file directly with the nrfjprog tools instead of the nRF Connect Desktop software.

Edit: I tried to flash the nRF52840-DK sniffer firmware on the nRF52833-DK to see if it would work but unfortunately it did not.

haakonsh Would be nice to get a nRFSniffer that works on the nRF52833-DK. Thanks.
