Hello, Sorry if this has all been asked before. I am trying to setup a 6lowpan network using a Raspberry Pi 400 and Atmel REB233-XPRO modules (AT86RF233). I have 2 of each. I have wired the radio modules to the Raspberry Pi GPIO connector. If have created a device tree overlay that I think works when applied because I see this in the dmesg output: [ 36.388574] at86rf230 spi0.0: Detected at86rf233 chip version 2 I have installed 'wpan-tools' and 'lowpan-tools' I get what looks like good output when I run: $ iwpan dev wpan0 info Interface wpan0 ifindex 4 wpan_dev 0x1 extended_addr 0xc62e26eced5de562 short_addr 0xffff pan_id 0xffff type node max_frame_retries 3 min_be 3 max_be 5 max_csma_backoffs 4 lbt 0 ackreq_default 0 I tried to setup a 6lowpan network (based on things I googled) but pings didn't work, so I am starting over trying to confirm the lower level parts are working first. I set the pan_id to 0xabba on both systems. I set the short_addr to 0x0001 on one and 0x0002 on the other. When I try using wpan-ping (from 0x0001), I get: $ wpan-ping -a 0x0002 -c 5 PING 0x0002 (PAN ID 0xabba) 5 data bytes Hit 500 ms packet timeout Hit 500 ms packet timeout Hit 500 ms packet timeout Hit 500 ms packet timeout Hit 500 ms packet timeout I used "ip link set wpan0 up" (on both systems) and the result is the same, but I can see packets in wireshark on wpan0. A hardware person here suggested using a near field probe to see if we could detect any transmission. We didn't. So I don't know if the radios are actually transmitting. Any suggestions on where to go next? Thanks, Mark
