Here is the firmware pull request: https://github.com/openwsn-berkeley/openwsn-fw/pull/128/
List of files changed:
bsp/boards/python/openwsnmodule_obj.h - add rrt_vars_t struct to python OpenMote struct
inc/opendefs.h - add ringmaster port constant on which to listen to and send ring master packets
openapps/SConscript - add rrt as part of the default apps to be built with SCons
openapps/openapps.c - add rrt_init(), the initialization function for rrt resource
openapps/rrt/rrt.c - add rrt resource to openapps, with the code for handling all mote actions. A GET action sends confirmation to the ringmaster, a POST action accepts payloads and determines what to do next (forward, perform action, or nothing), and a DELETE (which unregisters a mote). rrt.c also defines a function sendCoAPMsg, which sends a char to either an address or a hardcoded ringmaster address
openapps/rrt/rrt.h - define function signatures to be used outside of rrt.c, as well as the rrt_vars_t struct
openapps/rrt/rrt.py - simple python program for testing python coap library functionality - no purpose
openstack/04-TRAN/opencoap.h - hardcoded ringmaster address added here
openstack/04-TRAN/openudp.c - add blocks for the ringmaster port in udp receive and send
openstack/SConscript - add proper path for rrt folder
projects/python/SConscript.env - add proper constants to get the proper objectification
