The packet structure and conversion info is provided in the appendices of the XServe manual. http://www.xbow.com/Support/Support_pdf_files/XServe_Users_Manual.pdf You may also use ConfigXML file pertaining to MTS420 board for this parsing/conversion info (found under \xserve2\configxml folder). I hope that helps, Giri

Thank you so much for all your help :) I have one final question though. I need to interface the GPS information with the rest of our project, which is written in TinyOS and Java. Would you happen to know the packet format of the data packet so that I can parse it and use it without MoteView? Or is there some way to send MoteView data over a socket or something? Thanks!

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.

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!

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: [2008/02/15 23:35:46] MTS420 [sensor data converted to engineering units]: health: node id = 2 battery: = 3278 mv humidity: = 28 % Temperature: = 26 degC IntersemaTemperature: = -78 degC IntersemaPressure: = -402 mbar Light: = 0.192361 lux X-axis Accel: = 533.333333 mg Y-axis Accel: = 96.446701 mg [2008/02/15 23:36:06] MTS420 [sensor data converted to engineering units]: health: node id = 2 battery: = 3278 mv humidity: = 28 % Temperature: = 26 degC IntersemaTemperature: = -78 degC IntersemaPressure: = -402 mbar Light: = 0.486144 lux X-axis Accel: = 533.333333 mg Y-axis Accel: = 101.522843 mg Thanks for all the help!

These are available in MoteWorks and an update has been posted to our knowledgebase. http://www.xbow.com/Support/wobjectDetail.aspx?id=50160000000KuHhAAK&typ e=Solution&page=0 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.

Any ideas? Thanks! On Fri, Feb 15, 2008 at 5:43 AM, Siirtola Harri <[EMAIL PROTECTED]> wrote: 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.

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.
