Hi Roger, The only big change is that I removed the packetlink layer from the default configuration. By default, the PACKET_LINK was enabled in Radiocounfig.h. This I have removed. Also, there were some logic problems in the old PacketLinkLayerP, where it would enable ACKS even if you did not request them. This is also fixed.
Try compiling with CFLAGS=-DPACKET_LINK enabled. If this does not fix the problem, then try using the old pacetlink code. Let me know how this works.
