nRF Sniffer for zigbee using nRF52840 can't decrypt zigbee frame correctly

[Cooler Joey]

Hi everyone, 

I'm using a PCA10056 board (nRF52840) to sniffer zigbee DPU, and using another 3 PCA10056 board excute the zigbee-light_control example. I already configured sniffer environment follow https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.0.0%2Fnrf802154_sniffer.html and received zigbee DPU in wireshark successfully.

But the weird thing is that zigbee frame cannot be decrypt correctly as follows although I already added the zigbee protocol Pre-configure key. Did I forget some steps?

Thank you for your help.

Hi,

I encountered the same problem mentioned in that thread. I've got 3 PCA10056 boards. I am using samples from nRF Connect SDK.
Device 1: network_coordinator sample
Device 2: light_bulb sample
Device 3: light_switch sample

I added both two keys in Wireshark, but unfortunately all packets received in Wireshark are encrypted.

Sniffer is configured on PCA 10059 dongle and I start sniffing before the devices are even powered up.
What I did wrong ?

Thanks in advance,

Pawel
