Now I made comparative tests between CC1101 and CC1125 modules. I
compiled the code without gnrc_sixlowpan_iphc module and run two nodes
with it. I turn on debug in gnrc_rpl_control_messages.c and in the radio
driver, so the incoming and outgoing messages could be observed. I
disabled address filtering in CC1125 transceiver. Thanks to that I can
obtain information whether the node has successfully joined the DODAG.
The aim is to configure RPL and wait until the forwarding table is filled:
CC1101 #1 (fe80::f6c8:4a52:b6:8a24) and CC1101 #2 rpl root
(fe80::e6c8:4a52:b6:8a24):
After the crucial frame is receved on #1 node joins DODAG:
