Hi, I am having problems communicating with a web server. I am sending data to a URL and embedding data into the URL which will then be processed on the server appropiately. I am however battling to coomunicate with the server and a exception is thrown every time. I am communicating straight via Ethernet on a Netduino Plus. I have setup a static IP address for the device. Below is some details on the exception being throw as well as a code snippet on where I make the call. Any help will be highly appreciated Debug extract: Sending reading to the server ...

I have a Netduino with a SM5100B Cellular Shield attached. I also have an external power supply which allows me to supply the required power to the Cellular shield. I had the SM5100B working perfectly. I could send AT commands and receive the relevant responses with no problems. I then proceeded to attach a analog probe to the Netduino and got that working as well. When I switched the probe to the Analog pin 5, the SM5100B stopped working and since then I have been unable to communicate with the SM5100B I have tried everything. I can open the COM2 port and send just a normal AT command, but then receive no response ... Not even with a 15 second timeout. Anybody have any ideas on what could be wrong and how to test the SM5100B?

Hi, I am having problems connecting and / or hosting a web service on the Netduino. I have created a small WCF Service and generated the relevant classes using MFsvcUtil.exe for the Netduino application. I then have to reference the DPWS Dll's. However, once these DLL's has been referenced, the application becomes to big to deploy to the Netduino. Even a small service that will be hosted on the device is too big Anybody have a possible solution around this problem? Thanks

Hi, I am quite a newbie at electronics and specifically the Netduino. I would like some help on setting up the relevant circuit to allow me to do the following: I have a sensor that communicates on a range of 4mA to 20mA based on what it senses. I would like to monitor this reading with the Netduino. The sensor has two outputs used to connect an external monitor (Netduino) to it. A postive and negative analog connection. Could anybody help me with what I need in the circuit to connect this sensor to the Netduino? I would really appreciate some help
