Hi, I am trying to sniff blip-1.0 traffic with TelosB motes. (Sniffing AM packets with BaseStation15.4 works for me without problems.)
Currently, I can only see blip's broadcast packets (mostly Router Solicitation). In the sniffing application I have enabled CC2420_NO_ADDRESS_RECOGNITION and CC2420_NO_ACKNOWLEDGEMENTS. Although blip-1.0 is not using AM, the following note in tos/chips/cc2420/CC2420ActiveMessageC.nc made me suspicious: "Note that snooping may not work, due to CC2420 early packet rejection if acknowledgements are enabled." Therefore I disabled PACKET_LINK and CC2420_HW_ACKNOWLEDGEMENTS in blip.extra. This amounts in several duplicate packets, but the unicast packets are still not sniffed. Has anyone sniffed unicast blip-1.0 packets (over the air, not on the tun interface) before? Thanks, Markus ------------------------------------------------ | Dipl.-Ing.
