I could not decrypt any NWK Layer packet using Ubiqua.

I think the NWK key is wrong. Where do I acquire the NWK key?

If you add a new device into network to capture the join process, Ubiqua can get network key over the air.

Hi YK

Thanks for the quick response as always.

But I'm still not getting the nwk key. Here's what I did:

1. Shut down everything.

2. Turn on Ubiqua

3. Initialize ZC in Z-Tool

4. Turn on ZED.

5. Saved the following file log file from Ubiqua.

Cheers

According to your sniffer log, it seems that your ZED had joined ZC. Try to erase chip to your ZED/ZC and download firmware to test from scratch to do sniffer log again.

Thanks for the suggestions.

But I was testing my own special code so I didn't erase the chip.

Ubiqua did start decrypting after I went to Tools -> Preferences->Security and fiddled with the keys. I don't know exactly what I did that helped, but I'm sure it's something quirky with Ubiqua.

Thanks again.
