This is a late reply I know but...

The webrequest timeout appears to be broken in the Netduino. If the webrequest target device is not available the request will simply wait forever and hang.

I got around the problem by wrapping the webrequest in a ping request. If the ping succeeds the webrequest is executed. If the ping fails the request is bypassed.

I used this version of Ping and it appears to work well:

Is there any way to use the netmf_toolbox_http_client with a timeout (like httpWebRequest)? If the site does not respond the client appears to wait indefinitely.  

Thanks

I managed to solve this issue. I was getting the following warning message which suggested where the problem lay:

Hi Chris,

Thanks for your reply. Unfortunately, I cannot do what you suggested. When I deploy this one line application referencing PWM... during the deploy Windows pops up a message saying:  

"The last device you connected to this computer malfunctioned, and Windows does not recognize it"

After that, MFDeploy will not see the board again until I reload the board with 4.3.1. All of my Netduinos (5) behave the same way. I guess it could be my PC. When this first happened I uninstalled everything (VS2012, MF framework SDK, Secret SDK) and re-installed it all. But the problem continued.

Could I use the MS PWM library instead? Can you think of any other troubleshooting approaches?

Thanks for your help.

Hi There,

I am running Windows 8, VS 2012 Premium, Netduino 4.3.1.

If I simply create an application that attempts to use the Secret PWM library (see below)... during deploy I get a message that the PC no longer recognizes the USB device. From that point the only recourse I have is to take the Netduino back to 'bare metal' and reload everything. Other than PWM all the other applications I load on the device seem to work without problem.

Thanks for any assistance.

Regards

Mike
