[Tinyos-help] serial forwarder bad packet vs bit CRC in CC2420

2010-11-19 Thread Correo de Wacka
Hi all, My last doubt is that, the bad packet that appears in the serial forwarder has to match with the bit CRC (wrong) of the CC24020 (MicaZ)?I've tested it, but I receive more wrongs CRC bits, that bad packets appears in the serial forwarder window. thanks for your time David

2010-11-19 Thread Morten Tranberg Hansen
Ok, so lets conclude. Assuming a reliable logging system DST_MSG is not needed if one logs when the max payload length test fails and RCV_BEACON might overload the logging system in dense networks. I guess what you need to decide is whether you want tinyos-main to log when the max payload length
