Hi Mateusz, as Kaspar already pointed out: the cc110x device is not a 802.15.4 device, but has both different physical and link-layer from 802.15.4. However, our sniffer script assumes the connected device is 802.15.4 device, so the PCAP data you are receiving in wireshark are marked as 802.15.4 frames, but they are not. As such the output is broken.
Hope this was helpful, Martine 2016-01-04 1:49 GMT+01:00 Mateusz Kubaszek <mathir.km.r...@gmail.com>: > Forgotten attachments... > > 2016-01-04 1:46 GMT+01:00 Mateusz Kubaszek <mathir.km.r...@gmail.com>: > >> Hi everyone! >> >> A few days ago I ran a sniffer application using CC1101 transceiver. >> Sniffing device is connected via UART<->USB adapter to PC.
