I use Xbee Pro S2C including 802.15.4 firmware in my project. There is a Ansi C library exist at the link below
I am trying to use this library. Zigbee, Digimesh and other firmware are supported, but I did not see any support for 802.15.4. Did I miss something? Or Digi does not officially support for 802.15.4 firmware in C library?
