The macro UARTDETECT_POLL is set to 3 seconds, so the base expects a
UartDetectMsg message before that. The Trawler application sends the message
every 2 secs. If you are sending only every 5 secs it would explain why UART
detect requests keep appearing.
I also have the problem where the base
would re-program my motes using Deluge, there
would occasionally be one instance where every node got the new image and
rebooted except one mote. The one mote would just consistently reboot
itself. Does the above explanation fit what was happening in my case?

Again, I can only talk about Boomerang sources .
Boomerang lowpower works upon the principle of synchronised global time known
to all motes in the network. All synchronised motes then go to sleep and wake

duty cycle.

I must confess to being a bit confused. Is it possible to use MultiHop over SPC?
Just using SPC wires itself to GenericComm. I cannot see an adaptor to MultiHop

If you call the commands outside of an event, they will be ignored.
Similarly, if you call back with the wrong command inside an event (like

will be ignored.

Hi. Sorry if this is a dumb question. How do you search the archives?
This page doesn't have a search box:
http://mail.millennium.berkeley.edu/pipermail/tinyos-help/
I just found this page through Google:
http://www.tinyos.net/search.html
However, searching gets me a 404 error, with
implementation of UniqueSendP in
tinyos-2.x/tos/chips/cc2420/unique/UniqueSendP.nc

I've just had the same problem and manage to cobble up a fix.
1. Set up environment variables correctly in your .bashrc script
# TOSROOT MUST be defined before it is referenced
export TOSROOT=/opt/tinyos-2.x
export TOSDIR=$TOSROOT/tos
export MAKERULES=$TOSROOT/support/make/Makerules
export

Are you requesting an acknowledgment before sending?
call PacketAcknowledgements.requestAck(myMsg);
call AMSend.send(0x0, myMsg, sizeof(my_payload_t));
Does it the software work as expected using software acknowledgments?

Also, are you calling CC2420Config.sync() to commit your hardware
acknowledgment changes to the CC2420 hardware?
call CC2420Config.setAutoAck(TRUE, TRUE);
call CC2420Config.sync();
// wait awhile
event void CC2420Config.syncDone() {
...
}
