Only for sniffing? That sounds strange. I think there should be some way to declare that we are returning via less bytes than we received, but I haven't found it at first glance and had no time to dig deeply there. In fact I think all libpcap/tcpdump/wireshark integration should be reviewed, updated and pushed upstream. However I had no time and Sergey (the man who originally did that stuff) also is silent now. > > Those are the changes required for *sharking packets from our stack. > > > >> > >> I'm able to sniff and decode 802.15.4 packets from the air.

It's a custom board but according to the author it should be compatible with Freescale's USB sniffer dongle. However it will take some time for me to get in touch with it. -- With best wishes Dmitry ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Linux-zigbee-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-zigbee-devel
