GNRC Fragmentation

Hi,

I have some large UDP packets to send with (around 500B). I wonder with GNRC message queue, I will do the link layer fragmentation & re-assembly by myself, or the GNRC will do it?

Best, Tianyuan

Hi,

the GNRC stack implements 6LoWPAN fragmentation & reassembly

http://doc.riot-os.org/group__net__gnrc__sixlowpan__frag.html

if I'm not mistaken it supports the IPv6 fragmentation extention too:
