hi, If i use Ieee154MessageC instead of ActiveMessageC, Ieee154Send, Ieee154Packet instead of AMSend[am_id_t id], AMPacket, RF230ActiveMessageC by RF230Ieee154MessageC,
If I use IEEE154FRAMES_ENABLED then how can I use RF230Ieee154MessageC and other Ieee named interfaces because RF230RadioC provides Ieee154Send, Receive as Ieee154Receive, Ieee154Packet interfaces which are defined under TFRAMES_ENABLED. I want to use Ieee 802.15.4 stack in MViz and TestNetwork applications but the problem is that merely by changing some AM interfaces with Ieee interfaces will it work? Will all these changes affect CTP interfaces and components used in application? how will i get to know that in my raw data from where Ieee frame is starting and ending? What should I do to analyze the received data that whether it is Ieee 802.15.4 standard or not? thanks.
