hi, you mean we can use RF230Ieee154MessageC configuration file instead of RF230ActiveMessageC ? and interfaces Ieee154Send, Ieee154Packet instead of AMSend[am_id_t id], AMPacket etc. present in tos\platforms\iris and tos\chips\rf2xx\rf230. so can you tell me how to use and where to wire these interfaces? Actually i am not understanding where to make changes if we want ieee 802.15.4 mac? thanks.
