nRF Sniffer 2 not capturing Mesh packets

[Paulo.Zacarias]

Hi,

I'm trying to capture Mesh packets using nRF Sniffer 2.0.0 and nRF52 DK while running the Light switch demo, but so far I haven't been able to capture any packet that I could identify as belonging to the Mesh network.

I do capture a lot of other packets like SCAN_REQ or ADV_IND, even with the Mesh nodes off.

I followed the instructions on nRF Sniffer User Guide v2.1, and I'm using Wireshark 2.4.6, Python 2.7.14 and pyserial 3.4. My Adv Hop settings are as default: 37,38,39.

Besides not being able to capture Mesh packets, I also often get the following error message: "Unable to send control message: Invalid argument." usually followed by some error starting with "Error by extcap pipe: Exception in thread Thread-3:"

I'm also using J-Link V6.30.



I fully followed the User Guide, so I really don't know why I can't see any Mesh packets.

Additionally, using btle.advertising_header.pdu_type == 0x2 filter in wireshark doesn't help either, I see ADV_NONCONN_IND packets but from one source address only, instead of 3 (1 client and 2 servers).

 

What could be the problem?

Hi!

and I'm using Wireshark 2.4.6, Python 2.4.14 and pyserial 3.4.

The user guide states, under required software;

• Pyton v.2.7.x

Did you mean to write Python v.2.7.14? Or are you using another version?

Best regards,
Joakim.

Hi Joakim,

Sorry, I meant Python 2.7.14, yes.
