Dear all, In the "Transmission of IPv6 Packets over IEEE 802.15.4 Networks" Internet Draft, section Dispatch type and Header page 7, is mentionned that ".. other non-LowPAN protocols that wish to coexist with LowPAN nodes should include a byte matching this pattern (00 xxxxxx) ..".
I had a look at the ZigBee network header and especially at the Frame Type sub-field (the 3 first bits after the 802.15.4 MAC header). For acknowledgement and command frames, the Frame Type value is either 010 or 011 (data frames start with 00). Consequently, it might happen that you get a match with a LoWPAN pattern, and then a problem of coexistence between LowPAN nodes and ZigBee nodes. I would like to know if this coexistence issue was raised before and if it is a matter for the 6LoWPAN WG.
