Re: [Tinyos-help] Help me with power range and signal strength!
Many users (including me) have had no success using the CC1000Control interface and the setRFPower commands. The way I did it was to edit the CC1000Control.h file in /tos/system/platforms/mica2. Ive forgotten the excat location now but there is a 2-D array called PARAM..something somewhere. In the xxxMhz array (xxx is the radio freq of the motes u are using..there is a seperate array for each type of freq) change the value of the PA_POW variable. (this is a register in the CHIPCON chip that can be used to adjust the transmitter power). By default it is 0xff on MICA2 motes. When i changed it to 0x00 i got a range of about 4-6 feet in an indoor lab environment.

Hi
Use the formula on pg 28 of this document.

also u have declared data in MyMsg to be an array of size 18 ie it runs from 0 to 17 and u r using
data[18] is it right just check that.

Hi all!
I searched in the archieves and found some of the topics that disscuss about power range however I still have problem with it.
in the CC1000ControlM at the line:
// Set default parameter values // POWER 0dbm gCurrentParameters[0xb] = ((8 CC1K_PA_HIGHPOWER) | (0 CC1K_PA_LOWPOWER)); call HPLChipcon.write(CC1K_PA_POW, gCurrentParameters[0xb]);
I guess I can make a change to power range here so I make change :
gCurrentParameters[0xb] =1;//I want to change to the minimum power range call HPLChipcon.write(CC1K_PA_POW, gCurrentParameters[0xb]);
After that I recompile my program and run it. However It seems that my change does not go in to effect (the range is still large).
Can you tell me the correct way to make the change to the power range?
I have one more question about signal strength.
I made the change at the TOS_Base, I try to read the signal strength from TOS_Msg
event TOS_MsgPtr RadioReceive.receive(TOS_MsgPtr Msg) {
cmd= (struct MyMsg *)Msg-data;
temp1 = (int8_t) (((Msg-strength)8) 0xF);//take 8 MSB
cmd-data[17] = temp1;//put in to packet at data[17]temp2 = (int8_t) ((8(Msg-strength)) 0xF);//take 8 LSBcmd-data[18] = temp2;//put in ton packet at data[18]
..
Here is MyMsg structure:
typedef struct MyMsg { uint16_t seqno; int8_t action; uint16_t source; uint8_t hop_count; uint16_t destaddr; int8_t data[18];} MyMsg;
After that, I use Listen program to read signal strength value, however all the times these values are always 0 or 1 (convert to decimal number). Can anyone tell me is this a correct way to receive signal strength? If correct, how canconvert this value to dBm?
many thanks!

[Tinyos-help] Mica2 VS MICAz
Hi, I am using Xlisten program to interact with data from XSensorMDA300 and XSensorMTS300 programmed in Mica2 motes. I have used both mica2 and micaz to recieve data from MDA300 and MTS310 boards. I am trying to figure out which one of these motes is better for collecting the data from the motes using both these sensor boards. (I am collecting data from 6 motes) In terms of data loss I have seen in my case that data loss is more in micaz over the same distance. Range of mica2 seems to be more than micaz. Am i infering currectly? What other differences exist? which one should be preferred? Any suggestion will be highly appreciated. thanks in advance. -sumit McGill university ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

RE: [Tinyos-help] current consumption on MicaZ in tinyos-2.x
Hi Razvan,
If you put the ATmega128L to extended standby, you should measure ~20uA.
If the cc2420 radio oscillator is still on (but radio is in standby) you
should measure a total system power of ~50uA.

Subject: [Tinyos-help] current consumption on MicaZ in tinyos-2.x
Hi!
I'm trying to verify the current consumption on MicaZ and here are some
results that I would like some feedback. :-)
The first test I did was to tun the Blink application and measure
the current when the leds where off. The result was 0.14mA.
The next test was to change the Scheduler.taskLoop code in
tos/SchedulerBasicP.nc to put the mote in different power saving modes.
The code I used, for entering in Extended Standby mode for example, was:
command void Scheduler.taskLoop()
{
for (;;)
{
MCUCR =
(MCUCR 0xe3) | 1 SE | (1 SM2) | (1 SM1) | (1
SM0);
sei();
asm volatile (sleep);
cli();
}
The results I got are:
- Idle: 3.94mA
- ADC NR: 1.35mA
- Power Down: 0.13mA
- Power Save: 0.13mA
- Standby: 0.27mA
- Extended Standby: 0.27mA
I performed the measurement using a Extech Multimeter [1] and I waited
till the current stabilized. I power the mote using a 3V power source.
The
application I run is an empty one (just one component, MainC).
So my question is: can someone confirm/infirm the above values? :-)
And one more thing: I have a few MicaZ motes burned with some old code
(a
monitoring application) that achieves 0.07mA in the sleep mode. I tried
to
recompile the application with the current tinyos-1.x and the current
consumption I got is 0.5mA. In the same tinyos-1.x I also run a Blink
application which calls PowerManagement.enable() in the init() and I got
0.14mA. Does anyone has any idea about what is the cause of the
difference? :P

So the values I'm getting are indeed too high. The question is: where is

Hi Razvan,
If you put the ATmega128L to extended standby, you
should measure ~20uA.
If the cc2420 radio oscillator is still on (but
radio is in standby) you
should measure a total system power of ~50uA.

Subject: [Tinyos-help] current consumption on MicaZ
in tinyos-2.x
Hi!
I'm trying to verify the current consumption on
MicaZ and here are some
results that I would like some feedback. :-)
The first test I did was to tun the Blink
application and measure
the current when the leds where off. The result was
0.14mA.
The next test was to change the Scheduler.taskLoop
code in
tos/SchedulerBasicP.nc to put the mote in different
power saving modes.
The code I used, for entering in Extended Standby
mode for example, was:
command void Scheduler.taskLoop()
{
for (;;)
{
MCUCR =
(MCUCR 0xe3) | 1 SE | (1 SM2) | (1
SM1) | (1
SM0);
sei();
asm volatile (sleep);
cli();
}
The results I got are:
- Idle: 3.94mA
- ADC NR: 1.35mA
- Power Down: 0.13mA
- Power Save: 0.13mA
- Standby: 0.27mA
- Extended Standby: 0.27mA
I performed the measurement using a Extech
Multimeter [1] and I waited
till the current stabilized. I power the mote using
a 3V power source.
The
application I run is an empty one (just one
component, MainC).
So my question is: can someone confirm/infirm the
above values? :-)
And one more thing: I have a few MicaZ motes burned
with some old code
(a
monitoring application) that achieves 0.07mA in the
sleep mode. I tried
to
recompile the application with the current
tinyos-1.x and the current
consumption I got is 0.5mA. In the same tinyos-1.x I
also run a Blink
application which calls PowerManagement.enable() in
the init() and I got
0.14mA. Does anyone has any idea about what is the
cause of the
difference? :P

Re: [Tinyos-help] where to find TEP104 and TEP105 for tinyos-2.x

Those two have pretty much timed out (haven't been discussed in almost two years); they might be revisited at some point in the future, but right now they do not reflect 2.0 and I doubt they are consistent with anything. The reference to them in 2 should be fixed (I just did) to point to 116.

Fwd: [Tinyos-help] Help me with power range and signal strength!
-- Forwarded message --From: Aditya Bhave [EMAIL PROTECTED]Date: Jun 29, 2006 12:42 AM
Subject: Re: [Tinyos-help] Help me with power range and signal strength!To: bhushan bhatt [EMAIL PROTECTED]You need to modify the
CC1000Control.h file in tos/system/platforms/mica2.Im assuming youre motes freq is 914 Mhz.In
that case there is a 2D array called CC1K_Params.Look for
the PA_POW variable under the 914 Mhz range (there is a seperate
row for each type of freq). Look in row 1. It is presently
// PA_POW 0x0b ((0x8CC1K_PA_HIGHPOWER) | (0x0CC1K_PA_LOWPOWER)),
//0xffChange the above to// PA_POW 0x0b// ((0x8CC1K_PA_HIGHPOWER) | (0x0CC1K_PA_LOWPOWER)), 0x00You
can see that I have changed PA_POW to the value 0x00 FROM 0xff
(default). The 0x0b (decimal number 11) is not a value...it indicates
the position of the element within row 1 of the CC1K_Params array. By giving diff values to PA_POW from 00 to ff, you can change the range.Let me know if it works.
If you are using a diff freq mote, change the PA_POW variable corresponding to that freq

I have the same problem and tried to control the power by changing
CC2420 Radio file for tmote but i still cant get the desired range. I
still get range more than 30 feet. Does someone know and have reduced
the range for tmotes ??

The way I did it was to edit the CC1000Control.h file in
/tos/system/platforms/mica2. Ive forgotten the excat location now but
there is a 2-D array called PARAM..something somewhere. In the xxxMhz
array (xxx is the radio freq of the motes u are using..there is a
seperate array for each type of freq) change the value of the PA_POW
variable. (this is a register in the CHIPCON chip that can be used to
adjust the transmitter power). By default it is 0xff on MICA2 motes.
When i changed it to 0x00 i got a range of about 4-6 feet in an indoor
lab environment.

Hi
Use the formula on pg 28 of this document.
http://www.xbow.com/Support/Support_pdf_files/MPR-MIB_Series_Users_Manual.pdf also u have declared data in MyMsg to be an array of size 18 ie it runs from 0 to 17 and u r using data[18] is it right just check that.

Hi all! I searched in the archieves and found some of the topics that disscuss about power range however I still have problem with it.
in the CC1000ControlM at the line: // Set default parameter values // POWER 0dbm gCurrentParameters[0xb] = ((8 CC1K_PA_HIGHPOWER) | (0
CC1K_PA_LOWPOWER)); call HPLChipcon.write(CC1K_PA_POW, gCurrentParameters[0xb]); I guess I can make a change to power range here so I make change : gCurrentParameters[0xb] =1;//I want to change to the minimum power range
call HPLChipcon.write(CC1K_PA_POW, gCurrentParameters[0xb]); After
that I recompile my program and run it. However It seems that my change
does not go in to effect (the range is still large).
Can you tell me the correct way to make the change to the power range? I have one more question about signal strength. I made the change at the TOS_Base, I try to read the signal strength from TOS_Msg
event TOS_MsgPtr RadioReceive.receive(TOS_MsgPtr Msg) { cmd= (struct MyMsg
*)Msg-data; temp1 = (int8_t) (((Msg-strength)8) 0xF);//take 8 MSB cmd-data[17] = temp1;//put in to packet at data[17]temp2 = (int8_t) ((8(Msg-strength)) 0xF);//take 8 LSB
cmd-data[18] = temp2;//put in ton packet at data[18] .. Here is MyMsg structure: typedef struct MyMsg { uint16_t seqno;
int8_t action; uint16_t source; uint8_t hop_count; uint16_t destaddr; int8_t data[18];} MyMsg; After
that, I use Listen program to read signal strength value, however all
the times these values are always 0 or 1 (convert to decimal number).
Can anyone tell me is this a correct way to receive signal strength? If
correct, how canconvert this value to dBm? many thanks! Tran!

[Tinyos-help] About Events and Commands
While going through the tutorials and apps in tinyOS, i found that the events of an interface are implemented in the modules that "use" them and the commands are "called" but not implemented in those modules, e.g., in Surge Application, the SurgeM.nc (the module) "uses" Send interface and implements the event Send.sendDone() and calls the command Send.send() in the "task" SendData(). My question is that where is the functionality for the Send.send() command ?Kindly someone guide me in this case because as far as i've understood, there should be another module that gives implementation of this command but i'm not able to find it.thankyouS Khan___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
