In Topic: Status of Firmware confusing
30 January 2012 - 02:36 PM
I downloaded the 4.2 beta 3 again. I had the problem of the "no response". Since then, I have a new pc running windows 7 64. I do not know if anything changed from the Oct time frame as far as download version. I started with Sam-ba and reinstalled everything. I was able to go into Visual Studios 2010 and with a copy of the program that I found here in the forums, I was able to write to a 2gb sd card. Yeh. Now for some almost good news. I was not able to write to a 8gb sd card. I installed 4.1.1 B1 and everything worked including reading and writing to the 8 gb sd card. The same card will not work in 4.2 b3. I went back and forth between the different beta releases and the results were consistent.
Once the community tells us that the .NET MF 4.2 firmware is stable, we'll make it an official release and post it on the Downloads page... Right now, there are some core bugs to work out still. [We're checking in some new bug fixes today to see how they affect stability.]

Not sure if windows xp was the difference or the speed of the machine that would not allow 4.2 b3 to work properly, unless there was a newer version that I downloaded from the first post from this thread.
I did have one problem with 4.1.1 b1 with the reading of the 8 gd card initially. Netduino+ was plugged into a usb hub that was plugged into a powered usb hub. That caused my machine to crash. I could not get Netduino to be recognized until I re powered the usb hub. I will try this setup with 4.2 once I can get 4.2 version to read a 8 gb sd card.
Thanks for all the hard work.

In Topic: GPS, GRPS and Google Latitude Tracking

I also have been interested in GPS tracking. I want to put a tracker on my new motorcycle. One, for security if someone takes it. But I doubt that will happen. Two, when I go on a trip it is logged and if I need something people will know where to find me.
.
The most popular commercial products out there use GSM which probably the easiest and most effective way for a commercial product. However, being I am working on a DIY solution I am going to look at APRS. APRS is a data transfer system built on top of ham radio. That does mean I have to get a ham radio license. Check out aprs.fi to see if there is anyone using it near you.
Another option that I was thing about would be to use GPS and tie it into the ham radio APRS system using netduino. You would need a radio, but with many solutions out there already, it might not be feasable, but fun to do.

One more thing to mention. My netduino and netduino_plus boards are stamped as at91sam7x512 and on the next line is has AU. In sam-ba there is no at91sam7x512-au in the list so I have been picking the -ek board type.Very interesting. Thanks for the additional info, Bob.
