Bad FCS #6

Closed MikeColeGuru closed 2 years ago

MikeColeGuru commented 2 years ago

I am aware that the firmware excludes Bad FCS packets and I don't know if this will help the project.

When I have the original TI firmware on my CC2531 dongle and read packets into Wireshark, it requires me to set a different FCS format otherwise all the packets come out as Bad FCS.

Once I set it, all of those Bad FCS errors go away.

The setting is "FCS Format" under Protocols->IEEE 802.15.4 and the option that works is "Ti CC24xx metadata"

TI FCS format

As I said in #5 I am not receiving any packets from killerbee zbdump with the Bumblebee v2.1 firmware. I think they may all be Bad FCS? I don't know if the above issue is an issue or not.

I hope this helps in some way. Let me know if you want me to test anything or help in any way.

I found the main issue with the capture. 'zbdump' on your develop branch has some errors which I corrected and got it at least capturing. It however USB Overflows when large bursts of packets come in. I am in a dense zigbee area.
I am using FW 2.1r1 with latest of your version of Killerbee

I'm going ahead and close this issue.
