Hi, Here is how I set the network: modprobe at86rf230 iwpan dev wpan0 set pan_id 0xbeef ip link set wpan0 up ip link add link wpan0 name lowpan0 type lowpan ip link set lowpan0 up Then I try to do: ping6 -I lowpan0 fe80::a8af:ac69:e53e:c7f1 Nothing is sent. (I checked by sniffing the SPI pins). No errors from ping6 or other layers in the network stack. root@OpenWrt:/# ifconfig lowpan0 Link encap:UNSPEC HWaddr 05-38-09-06-90-E0-5E-3E-00-00-00-00-00-00-00-00 inet6 addr: fe80::738:906:90e0:5e3e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1280 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) wpan0 Link encap:UNSPEC HWaddr 05-38-09-06-90-E0-5E-3E-00-00-00-00-00-00-00-00 UP BROADCAST RUNNING NOARP MTU:127 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:1 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:300 RX bytes:0 (0.0 B) TX bytes:75 (75.0 B) (TX bytes:75 (75.0 B), seems to be sent when you up lowpan0 ?) Is my settings right? What should I check to make sure the data goes from each layer of the network stack?
