Hi,
I use the CTP CollectionC to forward my data to the sink. Then I want to
send the data to the PC using the serial port. When I use AMSend for
normal sending or the CollectionC in the lqi package, I just can forward
the messages to the serial port to my Java application, which uses for
my d
Hi,
I use CollectionSenderC and CollectionC of the ctp package to send my
data to the sink node.
I just use a timer to send a message each second and the node with id
zero receives it.
I only use two sensors.
Unfortunately, I always receive the packages many times, as you can see
below. The sen
I know know that there is a relation to MAX_RETRIES in CtpForwardingEngine.h
There is written:
/*
* The number of times the ForwardingEngine will try to
* transmit a packet before giving up if the link layer
* supports acknowledgments. If the link layer does
* not support acknowledgments it s
Hi,
I am confused about the wiring of these two components.
CC2420ActiveMessageC uses CC2420CsmaC
and
CC2420CsmaC uses CC2420ActiveMessageC
I wonder how this fits into the network layer architecture? I mean the
second case for me means that a lower network protocol makes use of an
upper one.
Hello,
we have the radio stack where we have the UniqueSend component. This
uses the DSN field. Now what if I renounce on the uniqueness? The field
DNS is most likely still sent inside the header. So why this layer
structure of the radio stack if the message formats are not layered?
Actually I
Hello,
I have synchronized timers on the sensors. When they send, all the
sensors would send at a time. This would produce collisions between the
packages. I would like to measure how many collisions there are. I
thought, I could do this in TransmitP, if I introduce a counter
somewhere. But I
Hi,
why does the example implementation in tinyos-2.x/apps/BaseStation use
atomic sections? I mean there is no async code...
Thanks
