Re: [Tinyos-help] CollectionC - Snoop.receive never called

TOS_NODE_ID or AM_BROADCAST_ADDR. Thus, snoop does not work. Best, Daniel -- Daniel Minder University of Duisburg-Essen, Networked Embedded Systems Bismarckstr. 90, 47057 Duisburg, Germany Skype: d.minder ___ Tinyos-help mailing list Tinyos-help

Re: [Tinyos-help] difficulty understanding CC2420TransmitP

before (we are in RXFIFO.readDone which means we have received some bytes) we need to end the FIFO access before we can send an SACK command strobe. Best, Daniel -- Daniel Minder University of Duisburg-Essen, Networked Embedded Systems Bismarckstr. 90, 47057 Duisburg, Germany Skype: d.minder

Re: [Tinyos-help] CC2420 - attempts to send

does not even notice if the channel is busy. It only resends if there is no ACK. The question was what happens if the channel is always busy. Then, in CC2420TransmitP BackoffTimer.fired() is called, CCA is sampled and the BackoffTimer is restarted. This happens forever. Best, Daniel -- Daniel

Re: [Tinyos-help] difficulty understanding CC2420TransmitP

to TX mode takes some time, and in this time the channel is free. So, if we would start immediately we would destroy an ACK. Therefore, we wait a little bit longer. Best, Daniel -- Daniel Minder University of Duisburg-Essen, Networked Embedded Systems Bismarckstr. 90, 47057 Duisburg, Germany Skype

Re: [Tinyos-help] ACK without checking address

. What if a nearby node, which is not the recipient of the data packet, happens to send an ACK with the same DSN? I've seen in simulations that I get wrong ACKs from other nodes as you assumed. Best, Daniel -- Daniel Minder University of Duisburg-Essen, Networked Embedded Systems Bismarckstr. 90

Re: [Tinyos-help] question about tymo

. It's up to you if you want to follow their approach. The maximum wait time will also depend on your network. Best, Daniel -- Daniel Minder University of Duisburg-Essen, Networked Embedded Systems Bismarckstr. 90, 47057 Duisburg, Germany Skype: d.minder

[Tinyos-help] LPL with Unicast on CC2420

this behaviour (first increase MIN_SAMPLES_BEFORE_DETECT, later MAX_LPL_CCA_CHECKS)? Is there a problem with LPL on CC2420 and unicast? Shall ACKs be disabled for unicasts? Will the default values for both constants be increased in the future? Best, Daniel -- Daniel Minder University
