I am a beginner in TinyOS (version 1.1.15). I hope someone would help me
answer the following questions. I am sorry for the long email.
1) We have some micaZ motes. With the default makefile of TinyOS (say for the
Blink apps), I couldn't "make micaz". So, I replaced the original TinyOS
makefile with the one on the XBow CD. The contents of this XBow make file are
as follows:
== BEGIN ===============
COMPONENT=Blink
XBOWROOT=%T/../contrib/xbow/tos
PFLAGS= -I$(XBOWROOT)/platform/mica2 <=== WHY MICAZ DOES NOT WORK ?
include ../MakeXbowlocal
include $(TOSROOT)/tools/make/Makerules
== END ===============
If I use this make file (i.e. use "mica2" in this file), and "make micaz"
everything works fine. However, if I replace "mica2" with "micaz" in the
makefile, and "make micaz", I get compilation errors as follows:
== BEGIN ===============

function `tryToSend':

implicit declaration of function `CC2420_FIFOP_INT_CLEAR'
== END ===============
So, should I use "mica2" or "micaz" for the makefile ? Using mica2 seems to
be working fine, but it potentially creates some errors as mentioned in my next
question. Using "micaz" may need some tweaks for the compiler to work but I
really don't know how to do it.
2) So I had to use the "mica2" option in order for the make file to work. I
compiled and loaded TOSBase on one mote. I ran Serial Forwarder (with argument
[EMAIL PROTECTED]:mica2) and LISTEN, and was to received some data from another
mote running SenseToRFM.
If I change the argument of Serial Forwarder to [EMAIL PROTECTED]:micaz,
Serial Forwarder generates runtime errors about packet having wrong format. I
guess that is because mica2 and micaZ use different packet formats as I read
about it somewhere. So, probably, the micaZ mote that runs SenseToRFM sends out
packets in mica2 format which was not expected by SerialForwarder. Is that
right ? My concern is that it leads to the error mentioned in question 3.
3) So I had to use [EMAIL PROTECTED]:mica2 for SerialForwarder. I was able to
run LISTEN and get data. But when I tried to use tools/BcastInject , I always
got "write failed" in serial forwarder. The first time I run tools/BcastInject
, the Yellow lights is turned ON. And it will be ON forever regardless of you
run BcastInject to turn it off later.
My doubt is that the packet was sent out, but was not interpreted properly
by the external mote due to the difference in packet format (mica2 vs. micaz).
The 3 issues mentioned above seem so related to me. I would really
appreciate it if someone could shed some light on these issues.
Thank you very much.
Heo
