Robert,
The delay value that you specify using setRetryDelay() starts a timer
after the first packet transmission attempt is done. So 2) would be the
case. You can checkout the implementations in
/tos/chips/cc2420/link/PacketLinkP.nc.

In TEP 126 (

for the PacketLink layer, there is a command called "setRetryDelay." It is

hi to all,
Can anyone say, what is the maximum and minimum packet send and receive times
on an average ( for TOS_Msg messages ) from one mote to other or to base
station shoule be.
Thank You

I wrote a C code for some application using msp430 which contain these lines
#pragma vector=TIMERA0_VECTOR
__interrupt void timerA0_ISR(void){
// some code
}
when i write same in nesC it shows error, Can anybody help me to write
interrupts in nesC
Thank You

Thank you very much for the reply.
I accept your suggestion. I will move my second send() to sendDone().
Thanks again!

It may be possible with two instances of AdcReadStreamClientC. I haven't tried
this though. The AdCReamStreamClientC is wired to
tos.chips.msp430.adc12.Msp430Adc12SingleChannel. You might want to take a look
at tos.chips.msp430.adc12.Msp430Adc12MultiChannel interface which is used to

Thats OK. that can be done .. but what is the problem with MSP430ADC12Single
interface .. the program which i have sent in previous mail is not even
working for 2 ticks .. Am i using proper settings for ADC ?
I will check for your suggestion and let u know.

By default, there aren't any.

If I understand correctly your program worked with a Timer at 2 ticks,
but not at 1, right? If so check the return value of the Timer.start()
as there is a lower limit on the tick setting. It may be returning
an error and not starting. The limit used to be 3 in T1 for micas.

I'm posting this back to the help list to keep a record.
I don't know what you are measuring, send() to sendDone()?
If that's the case the times look to be long by an order
of magnitude.

Hi,
before sending a message you MUST be sure the previous one has been
completely sent. That means you should move the second call to the command
"send" within the event "sendDone".
Hope that helps you,

hi all,
I am working on a tinyOS project and in my code i have two message sendings
one after another. My intention is to send both messages every time. So, in
other words, i want to send the second message every time i send the first
message.
But, by looking at the debugging output, it seems to me

Hi ,
I am using two ambient light sensors, one is hamamatsu s7686 and another is
sfh5711. I need drivers for both of these sensors.
Please let me know is there any source from which i can get drivers for
these two sensor or i need to write drivers for them by
myself.
thanks in advance !
