[Tinyos-help] Set Transmit Power TinyOS2.x for acknowledgements

2010-01-18 Thread Vikram vik76
Hello, In tinyos-2.x we can set the global radio power of CC2420 by defining the CC2420_DEF_RFPOWER to a different value or we can change it dynamically on a per-packet basis using the setPower command from the CC2420Packet interface. How do I change the radio power for Packet Acknowledgments

[Tinyos-help] Packet tracking and duplicates

2010-01-18 Thread jcarneiro
Hello all, To prevent duplicate packets you would look at the origin and sequence number. This would then assume that you maintain a list of packets from every origin meaning probably memory problems, and possibly speed inserting new/checking duplicates. My question is what data structure are

Hi Guys, If you are thinking of writing a radio driver for a new radio chip, then I will be more than happy to help you out with that. I think the RF2xx driver is robust enough that with by rewriting the backend you will get all features (LPL, TimeSync, BLIP) automatically. Best, Miklos On Sat,

Hi, I don't know, but I'm thinking in loud. If you are using HW ack - it is probably impossible. So - you need to use SW ack. No more thoughts :) Arik On Mon, Jan 18, 2010 at 10:06, Vikram vik76 vi...@sify.com wrote: Hello, In tinyos-2.x we can set the global radio power of CC2420 by

Hi, Perhaps you should consider a sliding window mechanism, TCP style. BTW - how can you receive duplicate packets? The only reason I see - it can happen when the sender didn't receive the ack, although the receiver did send it. In this case, the sender will send the again the same packet. In

[Tinyos-help] Unexpected long delay to turn on the radio on MICAZ

2010-01-18 Thread Jun
Hi All, We recently observed an unexpected behavior of the CC2420 radio on MICAZ. I wonder if you had similar experience and any insights to this problem. We scheduled a timer to turn on CC2420 at a specified time. The radio, however, was turned on more than 200ms later than the specified time.

I am wondering whether you programed the directly connected node as the base station (otherwise, it doesn't accept commands from the serial port). It doesn't seem that you did because you commented out CFLAGS += -DDELUGE_BASESTATION in your makefile. Mike On Jan 18, 2010, at 12:20 PM, David
