nRF52840 DONGLE DFU ZIP about nrf-sniffer-for-802.15.4 HOT 7 CLOSED

Thank you for reporting this feature request.

The Device Firmware Upgrade (DFU) process supported by nrfutil is a feature for deployed products where firmware can be automatically or semi-automatically updated by end-users in a secure way. Most devices connected to internet (like smartphones, home automation devices, etc) sometimes ask to update their firmware. DFU from nrfutil is a feature that helps to implement secure firmware update procedures in end products. It involves security operations to ensure that the firmware being updated was created by the device vendor, to prevent firmware version rollback, etc.

nRF Sniffer for 802.15.4 is intended to be a simple development tool. It is not intended to be deployed as a part of final products. Because of that DFU or FOTA are overkill for this tool and these features are not planned in its roadmap.

The idea is that an engineer that intends to use the sniffer, uses nrfjprog (from nRF Command Line Tools package) or nRF Connect for Desktop to flash a sniffer device. If an engineer is interested in flashing newer firmware version, he/she should use nrfjprog or nRF Connect for Desktop again. However, the firmware is released rarely and because of that flashing newer firmware version is not an operation performed often by users.

@cederom, I've just read in NordicSemiconductor/pc-nrfutil#335 that you are interested in Bluetooth protocol. Please note that nRF Sniffer for 802.15.4 is a sniffer of 802.15.4 packets. 802.15.4 and Bluetooth are incompatible radio protocols.

Have a look at this tool to sniff Bluetooth protocol: https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE

As a result I got umodem device up and running :-)

ugen0.12: <ZEPHYR nRF Sniffer for Bluetooth LE> at usbus0
umodem0 on uhub0
umodem0: <ZEPHYR nRF Sniffer for Bluetooth LE, class 0/0, rev 2.00/2.03, addr 30> on usbus0
umodem0: data interface 1, has CM over data, has no break

It seems that you have nRF Sniffer for Bluetooth LE running. It is other tool than nRF Sniffer for 802.15.4. I believe you are interested in nRF Sniffer for Bluetooth LE, not 802.15.4.

However, if you need any help with nRF Sniffer for 802.15.4, please add your questions in this repository, or reopen this issue.

It seems I made the debug package with a blind guess of parameters just to make things work.. but it would be nice to have this nice DFU ZIP package provided too for platforms where only nrfutil is available :-)

Hello @hubertmis and thank you for quick response! Whoops, so this 802.15.4 sniffer is something different than BT sniffer, sorry and thanks for pointing this out, my first steps here :-)

If possible I am still interested in a DFU ZIP for DONGLE for this 802.15.4 (also for the BT project) :-)

There is only nrf802154_sniffer_dongle.hex provided and this cannot be uploaded to the DONGLE without external debug probe while there is a still DFU mode that we could use, right?

nRF Connect is not available on my platform so I need to use nrfutil and I stick only to the Open-Source :-)

from nrf-sniffer-for-802.15.4.

Well I can talk to the 802.15.4 sniffer over minicom terminal! I have generated DFU ZIP exactly the same way as described above. This probably means a problem with BT sniffer firmware. Maybe --sd-req needs something else than 0.

Why there is only one dedicated repo on github for 802.15.4 while not for BT? These solutions are very similar from the computer perspective :-)

Thank you for your feedback and time @hubertmis :-)

I've explained above why DFU is overkill for the sniffer project. We don't plan to add such feature.

You can upload firmware to dongle using nRF Connect for Desktop. You don't need debug probe or nrfutil.

nRF Connect is not available on my platform so I need to use nrfutil

Perhaps that's the source of the problem. I recommend to create a devzone ticket to run nRF Connect for Desktop on your platform.

Maybe --sd-req needs something else than 0.

I can't help you with bluetooth sniffer. Here again I recommend to create a devzone ticket.

The goal of these tools is similar, but the implementation is different. We are in the process of unification distribution methods of all tools delivered by Nordic. Currently some tools are deployed to GitHub, while other are not.
