I thought this would be simple, but I'm finding some inconsistent
usages in the demo apps and some of my own code...Anyway the working
examples (say, Oscilloscope) that I have for T1 do this:
In the config file:
OscilloscopeM.CommControl -> GenericComm;
Init the Comm system in the main Module:
command result_t StdControl.init()
{
...
call CommControl.init();
...
}
Otherwise your code looks like it should work fine.
You can also try putting a dbg line in timer.fired() to see if it works.

Hi all,
i was trying to implement an application that uses SendMsg interface.
I have looked previous posts (especially Event SendMsg.sendDone, may 2005)
and i have copied and pasted the code inside my application
Now, when i execute the application, it seems like to be in an infinite
loop, with an output like this
2: CLOCK: Setting clock rate to interval 231, scale 3
2: malloc data entry for clock event: 0xa05fbd0
2: UART initialized.
2: RANDOM_LFSR initialized.
2: malloc channel mon event.
2: malloc Channel Mon event data.
2: AM Module initialized
2: LEDS: initialized.
2: CLOCK: Setting clock rate to interval 231, scale 3
2: malloc data entry for clock event: 0xa05fc48
2: UART started.
2: Popping event for mote 2 with time 0:0:1.89305375.
2: Setting TOS_LOCAL_ADDRESS to 2
2: RADIO: Channel Mon event handled for mote 2 at 0:0:1.89305375 with
interval of 200.
2: RFM: Mote 2 got bit 0
2: Popping event for mote 2 with time 0:0:1.89470375.
2: Setting TOS_LOCAL_ADDRESS to 2
2: RADIO: Channel Mon event handled for mote 2 at 0:0:1.89470375 with
interval o
f 200.
2: RFM: Mote 2 got bit 0
2: Popping event for mote 2 with time 0:0:1.89475375.
2: Setting TOS_LOCAL_ADDRESS to 2
2: RADIO: Channel Mon event handled for mote 2 at 0:0:1.89475375 with
interval o
f 200.
2: RFM: Mote 2 got bit 0
etc etc
So, even if in the code there is a timer which calls the event
timer.fired(), this event never happens and so SendMsg.Send is never
called!!!!
However, i have found the problem: if i delete the line
Main.StdControl->Comm.Control
in test.nc everything works, but the event SendMsg.sendDone isn't throw,
and i don't want it!!!
What can i do?
Below i post the code of the appication
thanks
Antonio
