[Tinyos-help] Uart problem when it is interrupted by other interrupt!
Tinyos-help： Hello！ I use uart for transmiting data from PC to node, and the total length of the data part is 99. It worked on micaz, and when receiving the message, it just transmit back to PC to see if it be right through transmiting. When it works separately, all the sending data and receving data on PC is identical. But when I add a Timer using T3(System clock), and it get in T3 interrupt 10ms repeatly, the data sended and received is sometimes not identical(a data will be lose and will add 0 at the end of data part). I think it may be T3 interrupt interrupts the receiving state-maching. Has anybody met this probelem or known how to resolve it, hoping for your answer. Thanks a lot!

Re: [Tinyos-help] MIB520 Micaz Install problem
I don't know about the failure to enter programming mode, but if the problem that is causing this error is not the same causing the others, they could be due to not seating the motes properly on the board (which caused me many problems in the past).

[Tinyos-help] relationship between RSSI and distance
Hello, I'm trying to use RSSI value to obtain the distance between two sensor nodes mica2. I know that a lot of such experiments are made and that a lot of people use this method. However, when I do the experiment, I obtain unexploitable results: - between 0 and 70 cm, I obtain always the same RSSI. - above 150cm, all values of RSSI are possible. More strange: i do the same with micaz, and the results are exploitable. For information, I am using rcv_packet-strength to obtain RSSI knowing that the transmitted power is always the same. Can anybody tell me if it possible to use mica2 and RSSI to obtain distance and if yes, how to do that and why I didn't manage?

[Tinyos-help] TinyOS Java SDK System.exit() calls
Hi All, I am building the MoteIF interface into a larger application, and noticed that there are about 50 calls to System.exit() throughout the TinyOS Java API. While its understandable to restrict operation when a mote is not connected to the gateway host machine, calls to System.exit halt the entire java application. So far, I have found the only way to get around this is to define a new SecurityManager to manage all calls to System.exit, although this is less than ideal. Is there any plans to implement exception management in place of these calls, so mote interface-related failures can be degraded gracefully? If not, would this be a worthwhile goal to extend the flexibility of the API?

Hi there, According to the TinyOS tutorial 1.x, group id of motes can be specified in the makerule file and accessed via variable (uint8_t TOS_AM_GROUP). Currently, I'm experimenting the dynamic group id assignment rather than at the compile time. However, the system didn't allow me to assign new value to TOS_AM_GROUP. Is there any solution I can change the group id of motes in the programming rather than manually do it at the compile time?

RE: [Tinyos-help] Some confusion on the classic nesC paper.
Dear Philip, (1) Yes, I see. Another question relates to this: you said that the call graph of nesC code is fully known at compile-time. I conjecture that the component diagrams can be treated as call graphs in programming literature, and since the wiring relationships among components are totally determined, the call graph is also determined at compile-time. Could you confirm my understanding? (2) I understand what you mean. However, I think in the application level, there is no primitives that can alternate interrupt enable bits. So, does it mean application developers will not raise data races if they obey the race-free invariant?

[Tinyos-help] problems when using 2 motes with oscilloscopeRF?
hey there , I installed 2 mica2 motes with OscilloscopeRF to have to be displayed on the java applet( oscilloscope ) . but it gives me weird output .. the graph of one of the mote cancels the other instead of being displayed as a seperate line with different colour. I suspected that because both motes are sending the data using thge same frequency or using the same channels . ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] RSSI
so, if I just need to know whenever the RSSI CCA I can get it in the two
following ways (provided that the radio is in RxMode)
event result_t Timer.fired() {
/* First method */
uint8_t status;
uint16_t rssi_reg;
status = call HPLChipcon.cmd(CC2420_SNOP);
while( (status RSSI_VALID) 0x01 ) {
status = call HPLChipcon.cmd(CC2420_SNOP);
}
rssi_reg = call HPLChipcon.read(CC2420_RSSI);
/* Second method */
if( TOSH_READ_RADIO_CCA_PIN() )
// do something
is that correct?

Re: [Tinyos-help] RSSI
sorry, I meant something like this:
event result_t Timer.fired() {
/* First method */
uint8_t status;
uint16_t rssi_reg;
status = call HPLChipcon.cmd(CC2420_SNOP);
while( !((status CC2420_RSSI_VALID) 0x01) ) {
status = call HPLChipcon.cmd(CC2420_SNOP);
}
rssi_reg = call HPLChipcon.read(CC2420_RSSI);
/* Second method */
if( TOSH_READ_RADIO_CCA_PIN() )
// do something

Re: [Tinyos-help] problems when using 2 motes with oscilloscopeRF?
I'm not up on how the Oscope program works, but you may be getting overlays because both re-Motes use the same ID. Try installing them with different IDs ala: make mica2 install.N where N is a unique integer.

[Tinyos-help] Decoding the contents of a Serial frame returned by TestNetwork App (again)
Please help me shed some light in this!
Thank you!!

Subject: Decoding the contents of a Serial frame returned by TestNetwork App
(again)
To: tinyos-help@millennium.berkeley.edu
(this is a repost from a last month's mail that I didnt want to see go
forgotten)
Hello all;
Some weeks ago I asked about the exact contents of a frame I was receiving
through the serial port, of which I couldn't decode whatsoever (first mail
here:
http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2007-June/025739.html
).
With the help of some people (Alexander Becher, Steve McKown, David Moss and
Benjamin Madore), we managed to make some sense out of it. However, I am
reaching that time period where it would be really handy to have the rest
cleared.
So summing it all up, I receive this in the serial port (example frame):
7E 45 00 FF FF 00 00 13 00 EE 00 01 00 00 00 07 80 EE 00 07 00 80 00 00 00
00 20 00 00 53 63 7E
and the sent structure is like this:
typedef nx_struct TestNetworkMsg {
nx_am_addr_t source;
nx_uint16_t seqno;
nx_am_addr_t parent;
nx_uint16_t metric;
nx_uint8_t datah;
nx_uint8_t datal;
nx_uint8_t hopcount;
nx_uint16_t sendCount;
nx_uint16_t sendSuccessCount;
} TestNetworkMsg;
the platform is the MicaZ and the app is the TestNetwork.
we've went this far on the decoding process (* marks confirmed field):
*7E : Framing byte, denoting start of packet
*45 : Protocol Byte (NO_ACK)
*00 : Packet Format Dispatch Byte
*FF FF : destination address (from UART)
*00 00 : source address (root node)
13 : length
00 EE : Collection ID (from CTP) ?? / Type ?? / Destination PAN Identifier
(from MAC Header)
00 :
01 : hopcount (seems out of place, but sure looks like it!!!)
00 00 : Destination Address (root ID=0) (from MAC Header) ???
00 07 : Source Address (from the MAC Header)
80 : sendCount ??? (this field increments like the seqno below)
EE : Collection ID (from CTP) ?? / Type ??
*00 07 : source
*00 80 : seqno
*00 00 : parent
*00 00 : metric
*20 00 : data
00 : ???
*53 63:two byte CRC
*7E : Framing byte, denoting end of packet
Can you help me?
Thank you for the (once again) inconvenience;
Pedro
