[Tinyos-help] Difference between ActiveMessageC and Ieee154MessageC
Hi All, I'm trying to use IPBaseStation code available in apps/IPBaseStation I find that RadioSend of IPBaseStation is wired to Ieee154MessageC. Why ActiveMessageC is not used here? What is the difference between ActiveMessageC and Ieee154MessageC. Thanks and Regards, Hari Hara Sudhan R ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] able to get the first packet but not the rest..........
I
believe that the problem is with your TOS message Buffer.
Try
this the code which resides in MOTE1 will be having this event
event
TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr m)
{
}
This
event returns a TOS_MsgPtr which is used to receive the next message.
event
TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr m)
{
return m;
}
If
you are not returning the TOS_MSgPtr you may receive the first message, but you
will not receive any further messages
Hope
this helps

hello
everyone,
again in
need of u guys help:)
i
am using tinyos 1.1.0 mica2 under windows. i use MIB510 programmer.
my
program does the following...
MOTE1
gets data from uart and transmits it to the MOTE 2
via radio. mote2
receives
the data via radio and does some changes and then sends back to the
MOTE1
via radio
i
am able to send many a packet of data from* mote1*... but only
able to
get the first packet and not able to get
the rest from *MOTE2*
//
i
am using two motes one (*MOTE1*) is used to get data (a fixed number of
data..as
of now its 10) from uart and the other one
*(MOTE2)*is
programmed
with genericbase. although
there is a slight change in
genericbase
code
(instead of sending to the uart
(when the mote is receiving data from the
radio) i am again sending the data to the radio. problem is
here.)
//
Regards
primalfear

[Tinyos-help] Help regarding the CC1000RadioM module
Hello Everyone, I went through the cc1000RadioM module. In that module I could find statements like call SpiByteFifo.enableIntr(); call SpiByteFifo.disableIntr(); Why are these interrupts disabled? In what situations we have to disable the interrupts?

[Tinyos-help] RE: Tinyos-help Digest, Vol 41, Issue 74
Hello every one, I want to do Byte level radio transmission and reception. My receiver application receives some junk data and I could not check whether my transmitter is sending the data correctly.

[Tinyos-help] Help regarding the Transmission of data
Hello every one,
Im doing a project in which the sensor mote is connected to
a RS232 device.
Sensor is having these properties.
Baud rate-1200 bps
Stop bit-1
Parity-none
Flow control-none
I have initialized the Mote UART by
async
command result_t UART.init()
{
\\ set baud rate to
1200
outp(767>>8, UBRR0H);
outp(767&0xff,
UBRR0L);
\\ set double mode
outp((1<
\\
set 7 data bits and 1 stop bit
outp(((1
<< UCSZ1) | (0 << UCSZ0)) , UCSR0C);
outp(((1
<< RXCIE) | (1 << TXCIE) | (1 << RXEN) | (1 << TXEN))
,UCSR0B);
return SUCCESS;
}
Now I have got the data from the RS232 device and broad cast
it to all other motes.
The base mote which is connected to the system gets the data
from the TOS Message and prints it on the terminal
Unfortunately, I couldn’t get all the data some data
is missing.
Is this because there is some mismatch in baud rate.
Please help me regarding this

[Tinyos-help] Swapping TOS message buffer Problem
Hi every one,
I have a problem with swapping tos
message buffer
I have to develop an application which has to receive a TOS
Message through air and then Broad cast the message.
The code is
TOS_MsgPtr msg_buff;
event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr m)
{
TOS_MsgPtr tmp=msg_buff;
msg_buff=m;
call Leds.greenToggle();
post SendData();
return tmp;
}
Basically im performing the buffer swap operation. But the
problem is I can receive only the first Message.
I think there is some problem with the buffer swap. Can any
one please help me regarding this.
Thanking you in advance

RE: [Tinyos-help] difference between events and async events
Hi Phil, I went through your programming manual. And in chapter4 I found this following example. Consider a packet layer on top of a UART. When the UART receives a byte, it signals an interrupt. In the interrupt handler, software reads the byte out of the data register and puts it in a buffer. When the last byte of a packet is received, the software needs to signal packet reception. Do u mean to say that the interrupt handler for receiving the byte through UART is an async event, and the sync event is one which handles the packet reception signal.
