Packet sniffer and GTS

Aitorhh

Other Parts Discussed in Thread: CC2420

Hi everyone,

I've working on IEEE 802.15.4 implementation and I use the CC2420 development kit with the Packet Sniffer progam (v. 1.3.1.0). I've seen that when I send a GTS request with length different to 1, the software always shows a GTS request with length equal to 1. With "length" I mean the field inside the GTS options, not the packet length.

I don't know if that issue was known before or not, but I haven't seen anything similar on the forum.

Best,

Could you post the raw-data of your packets please?

1. With GTS length = 1

2. With GTS length > 1

With GTS length = 1. Allocation. Tx 7484.gts_length_1.psd
- Raw data (hex): 23 80 59 34 12 02 00 09 21
With GTSlength = 2. Allocation. Tx. 8737.gts_length_2.psd
- Raw data (hex): 23 80 59 34 12 02 00 09 22

I attach the .psd file, in case you want to check them.

We have verified that this is indeed an error in he packet sniffer software. It will be fixed in the next release.

Thank you for valuable feedback.
