[Tinyos-help] GPS module of MTS420 not working

Here's something I would suggest you to try.
Program your MTS420 sensor Mote with /apps/xmesh/XMTS420 app and node ID
non-zero
Program the Base Mote with /apps/XMeshBase app and node ID=0
Then use XServe or MoteView to read the data.

Hi

I have acquired the MoteWorks SDK and installed the patch as given on
the web page. I'm now running into a problem with actually getting the
data. 

I have a MIB520 programming board, a micaZ board and the MTS420CC GPS
mote (with the ublox chip). I installed TestMTS420cc application
(apps/xsensor/XSensorMTS420CC/) on one mote, and attached the GPS board
to it. I then installed XSniffer on another mote, which stayed hooked up
to the computer. I run MoteView with the database mts420_results, but I
don't see any sensor information showing up in the table. Also, when I
tried sniffing the data with XSniffer and xlisten, I get a stream of
data with no fixed size (that xlisten is unable to parse). 

I would really appreciate any help with this as I'm completely stuck.

Thank you!

Nikhil

it would work seamlessly in any version of TinyOS.

	Thanks! I do have the new MTS420CC board. I downloaded the
drivers from the link you sent. I have a question though: Do I need to
load the /opt/tinyos-1.x/contrib/xbow/apps/XSensorMTS400 app or the
/opt/tinyos-1.x/contrib/xbow/apps/xmesh/XMTS420CC app? I get a ton of
compile errors when I try to compile the xmesh one, and the XSensor one
still doesn't give me GPS data when I use XListen. I did change the
SENSORBOARD variable in the XSensor makefile to  mts420cc. Is it
possible that I'm using an  old version of  TinyOS, or am I doing
something incorrectly? This is the output I get:

		Do you know if you are using MTS420CA/CB or MTS420CC?
The latter has a uBlox GPS receiver and requires newer GPS drivers.
These are available in MoteWorks and an update has been posted to our
knowledgebase.

		If you try to use older GPS drivers with the new
MTS420CC, you might not get GPS data.
		 
		If you believe that you have the older board and are
using compatible older drivers, please check your GPS antenna
connections and make sure that it is placed outdoors with optimal sky
visibility.
		 
		I hope that helps,

		It seems like I am getting all the MTS400 data, and that
there should be a separate packet with the GPS data which, if is 0x0a
packet is the heartbeat, never arrives.
		
		Any ideas?
		
		Thanks!

			IIRC, the 0x0a packet is the heartbeat (health)
packet that motes send indicating they're alive. Might be that XListen
won't parse it but it's not the source of your problem. The parsed
packet also looks odd, considering there should be some GPS info.
Although it reads MTS420, is the MTS400 app sending all required data? 
			 
			Sorry, haven't used MTS420 but wrote just to
give something to think about.

			Hi all
			
			In my previous message, I had mentioned that I
was using XListen with a CrossBow MTS420 mote and wasn't getting any
output on the screen. As it turns out, my sensor board was faulty. I'm
using another one now, and I get readings from all the other sensors,
but nothing from the GPS. I have installed the XSensorMTS400 app on the
board, and am using TinyOS 1.x. This is the output I get:
			
			[2008/02/15 04:31:31]
			error: no packet handler for tos type 0x0a
			[2008/02/15 04:31:31]
			MTS420 [sensor data converted to engineering
units]:
			   health:       node id = 2
			   battery:              = 3278 mv
			   humidity:             = 28 %
			   Temperature:          = 25 degC
			   IntersemaTemperature: = 24 degC
			   IntersemaPressure:    = 1011 mbar
			   Light:                = 4.600000 lux
			   X-axis Accel:         = 616.666667 mg
			   Y-axis Accel:         = 116.751269 mg
			
			I'm guessing that the line "error: no packet
handler for tos type 0x0a" might be the problem, but I have no idea how
to fix it. Any help would be highly appreciated!
			
			Thanks!
