nRF Sniffer for nRF54L15DK

[vytautas]

Hello,

Is it possible to make the nRF Sniffer for Bluetooth LE application work on a nRF54L15?

Hi, 

No, the following Nordic Semiconductor devices can act as a sniffer when they are programmed with the sniffer firmware:

• nRF52840 DK (PCA10056)
• nRF52840 Dongle (PCA10059)
• nRF52833 DK (PCA10100)
• nRF52 DK (PCA10040)

See Supported Development Kits and dongles.

Hi ,

nRF Sniffer for nRF54L15 , is this a limitation of the nRF54L15 hardware to be a sniffer.  Or is it a software limitation?

This is a SW limitation.

Hi,

Building the nRF52840 DK  from source

https://github.com/NordicSemiconductor/nRF-Sniffer-for-802.15.4

1.  is this the correct repo?

2.  The nRF52840 is detected and can configure channel and what not in wireshark yet no data is captured. Is there other things to check ,  I see with my other sniffer that there is traffic on the channel being monitored.

3. The python file was installed in nrf802154_sniffer.py , into /usr/lib64/wireshark/extcap (this is on fedora), is this the correct python file ? 

The naming is a bit different then the previous version (the nrf_sniffer_for)bluetooth_le_4.1.1 which the file is nrf_sniffer_ble.py . There is a sniffer API also when extracting the nrf_sniffer_for_bluetooth_le_4.1.1.zip from www.nordicsemi.com/.../download

I need to build from source as compared to using the pre-packaged hex file

4. Is there a way to configure to view all the channels if nrf802154_sniffer.py is the correct file?  nrf_sniffer_ble.py appears to allow for more of the announcement channels. 

Any guidance would be helpful.

There are 2 sniffers, one for 802.15.4 and one for Bluetooth Low Energy. These have a lot of differences due to the different protocols so you should not compare them against each other.

Why do you need ot build the code from scratch and can't use the pre-compiled and tested version?

[chuck rekiere]

We are attempting build radio_test, announcement code and sniffer into one hex file.  We have successfully built radio_test and announcemts into one executable.  Befor integrating the sniffer wanted to verify that the sniffer could be built and operate correctly. 

From your; comments above is this correct the 802.15.4 sniffer is only available for specific channels ( nrf802154_sniffer.py),  the Bluetooth Low Energy in nrf_sniffer_for_bluetooth_le_4.1.1.zip, is there source code for the Bluetooth Low Energy (one that can do all channels)?
