GPS - outofmemoryexception since WM6

[Agrartec]

Hello guys,

I have a problem that I can`t solve since I updated my PPC to WM6.
If I use a GPS-program then I get the error: "outofmemoryexception" in codeline :
If serial.InBufferCount>0 Then
GPS.GPSStream(Serial.InputString)

I`m already using the serial2.dll (didn`t work at all with the other one).
Same error occurs when I use the gps-example from erel.
And I didn`t have this error on WM5.

Does anyone have an idea what is going on there?

Cheers

(I hope this hasn`t been answered somewhere here, if so then sorry, I didn`t find it.)

Does it happen immediately?
Do other GPS applications work properly with your device?
Please try to install GPS4PPC and see if it works: http://www.basic4ppc.com/files/GPS4PPC.zip

Hi Erel,
no this does not happen immediatly. It can take 5 to 50 seconds after starting the GPS-receiver.
And this also happens with your "GPS4ppc".
But first it disconnected the GPS again after 4 seconds. Reconnecting gave me the same error at line 363.

What can this be?

Did you try to make a soft reset?
Other GPS applications work properly (not Basic4ppc apps) on your device?

[Agrartec]

Yes, I made a softreset and tried TomTom Navigator that works fine. But the B4ppc-programs still make the error.

Maybe updating the .Net CF will fix it.
There were some issues with the serial ports with .Net CF 2.0 / .Net CF 2.0 SP1.
Please make sure your device is installed with .Net CF 2.0 SP2.
You can create a new application, add the Hardware library and check Hardware.NetVersion value.
.Net CF SP2 value is: 2.0.7045
It can be downloaded here: http://www.microsoft.com/downloads/d...displaylang=en

If I try to install this update then my device tells me that it already has it in the ROM.
The strange thing: I send my programm to a friend who owns a Asus P535 with WM6. He does not have this problem, but he doesn`t get a satfix (right after a satfix with another prog).

I have two HTC P3300 (artemis) and both show the outofmemory-error. I installed another Rom with a lot of free memory to one of my devices, but its the same problem.

Can someone else who has a device with WM6 try out Erels GPSApp, please. And tell me if it works.

[Agrartec]

I`m still searching for an answer to this problem, so I found out that in the prog GPS4PPC follwing codelines seem to make trouble (however).

Sub Timer1_Tick
If serial.InBufferCount>0 Then
timeout = 0
GPS.GPSStream(serial.InputString) 'Takes the data received from the GPS to GPSStream.
Else
timeout = timeout + 1
If timeout = 5 Then mnuDisconnect_click
End If
End Sub

In my case the prog always disconnects the GPS after that 5 seconds and sometimes the errormessage from above occurs before.
So I think that the data doesn`t arrive.

At least one other person has a similar problem - see the second entry

http://nativemobile.blogspot.com/200...htc-p3300.html

"I also have problems with the GPS for this device. .... I'm using C# and the System.IO.Ports.SerialPort and got GPS working fine for other devices (WM5, PPC2003)."

No resolution posted though!

Thanks for that hint, agraham.

But in my case I could use the gps of my device under WM5 without any problems with Basic4ppc-progs. And every other gps-prog I found worked so far. Now, since I changed to WM6, I encounter this poroblem. Maybe it has to do with the new serial2.dll.
