[Tinyos-help] Snoop packets RF230

Hi all, I'm trying to snoop packets using RF230 iris mote. As I've read, If hard acks are enabled, you can't snoop packets, but,how am I able to snoop packets if I'm not using hardware acks??? Any makefile command?? Thanks for your time Best regards -Er wacka -

[Tinyos-help] Minimun Voltage IRIS

Hi everyone, I would like to monitor the batteries of some IRIS nodes and as far as I know the minimun power voltage they need is 2V. Is it correct? It would be helpful to know the minimun voltage they need to operate, just to send an alarm wether I detect that critical level and replace

[Tinyos-help] HardACK timeout and Retries

Hi Miklos, I've been reading all the post about ACK's on RF230. I would like to know wether is possible to change the timeout ACK for HARDWARE ACKs or is fixed by the transceiver. I've read int the datasheet that this timeout is 864 μs. Because softwareack timeout has to be increased till

[Tinyos-help] mesh network

Hi all, I've been reading all the networks protocols appear in the documentation, but I'm unable to guess which one is the simplest one to just creat a mesh network,instead of Tymo. And, is tymo available for iris motes?or just for telosb? Is there any other mesh network protocol for a non

Re: [Tinyos-help] CRC

with bad CRC from PC across the serial port to my base and I will detect these. What I need to do? Thanks David,Regards 2011/3/25 Correo de Wacka yo_wa...@hotmail.com Hi! I've disabled CRC check in mica2, micaz and iris motes. I mean, I can read packets with bad crc and register them in a log

[Tinyos-help] Maximum Throughput

Hi all!, Has anyone be able to reach 250 kbps as throughput? I've realized that it's the maximum, but, it's only theorical, how could I get the highest value? the bitrate of the serial forwarder ( 57600 bps with IRIS motes) is relevant? I mean, may be this value prevent to reach the

[Tinyos-help] Queue UART Size

Hi all, I'm testing the BaseStation which have UART_QUEUE_SIZE =12 and RADIO_QUEUE_SIZE =12. If I increase the values to 40, the basestation don't blink the leds, which is the real meanning of these fields? are the number of packets that could be saved in the queue (radio or uart)? If I don't

[Tinyos-help] read CRC in IRIS motes

Hi all, I'm developping a logger in Netbeans with IRIS motes, that save all the packets that are recieved by the basestation. I'm using a a modified version of the RssiDemo. The RssiBase includes the RSSI in the payload, I'm doing something similar, but not only with the RSSI field but also,

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

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

[Tinyos-help] some header fields.

Hi all, I've been reading some mails about the meaning of the fields rxInterval, timesync, tx_power and timestamp of the metadata of an CC2420 micaz mote. But I can't understand the meaning, I'm confused.I'm loging all the packets received by the BS to a file, just to monitor all the

[Tinyos-help] RssiDemo Mica2 RSSI to dBm

HI all, I'm using RssiDemo to measure the rssi, and I'd like to convert the value of the RSSI to dBm. I've used this conversion in the java program: rssi= msg.get_rssi(); Vrssi = (3*rssi/1024); RSSI = -50*Vrssi-45.5 ; System.out.print( Power: + RSSI + dBm ); But the

[Tinyos-help] Rssi mica2

Hi all, I'm trying to install the RssiDemo in three different pairs of motes separately (Mica2, MicaZ and IRIS) to evaluate the behaviour of these motes in my proyect, different distances, different . I've changed a line in the RssiBase as follows and it compiles perfect with the three
