Hello guys,
I'm using CTP and found some redundant transmission problem. I think it
retransmits redundant packets because PacketAcknowledgements.wasAcked is not
working well. On transmitter side, wasAcked() in
CtpForwardingEngineP.nc:SubSend.sendDone() sometimes returns FALSE although the

I just found that the wasAcked() function always returns FALSE if I don't
Hi guys,
I'm making a communication system using UART0, and it seems UART overrun
error frequently happens.
I read some document about UART, and it says if UART interrupt is not fast
enough, that error occurs.
I'm doing nothing but a UART transmission, so I'm suspecting CPU is doing
Hi, guys,
Does anyone have used uart0 and radio concurrently on telosb mote?
It seems even if I handle resource arbitration, if a radio packet arrives
during uart transmission, overrun error happens on uart.
I think it's because MSP 430 is too slow to handle radio interrupt within 69
Hi,
I found some articles about cc2420 data rate from mailing list.
Is it true that maximum reliable data rate is about 50kbps? (without any
interferences)
Actually I only achieved 30kbps, but I think it's because that I serialized
sending. (send - sendDone - send - .)
And I didn't
Hello, guys,
I'm making a program which uses radio and uart0 on the telosb mote.
Since the radio and uart0 share bus on telosb, I had to deal with resource
arbitration.
The thing is, when I made an uart0 manager like this, it dosen't work.
More specifically, after some time, I
Hi, guys,
I am struggling with some resource arbitration problem with CC2420 and
UART0.
What I want to do is, making UART0 serial stack as a default owner of USART
bus.
But it looks like it is not enough that I just connect default owner
interface to serial stack because it seems like
