#32068 find the right ip address on the network

Posted by ash on 16 July 2012 - 04:28 PM in Netduino Plus 2 (and Netduino Plus 1)

I want my NP to automatically connect to a web server. Is there a way of doing some sort of dns lookup or a list of devices on the current network etc. Cheers, ash.



#32099 find the right ip address on the network

Posted by ash on 17 July 2012 - 08:52 AM in Netduino Plus 2 (and Netduino Plus 1)

any examples of code on where i can get the list of devices attached to the network?



#32123 find the right ip address on the network

Posted by ash on 17 July 2012 - 11:16 AM in Netduino Plus 2 (and Netduino Plus 1)

its for a commerical application where several of theses Ap's on power up with auto locate a server connect and process data. We are trying to limit the technician's just to fit these boxes and replace if faulty. i was hoping not to ping as it will be a long process on these AP boards.



#32147 find the right ip address on the network

Posted by ash on 17 July 2012 - 02:17 PM in Netduino Plus 2 (and Netduino Plus 1)

Thanks Nak. Looks like its not going to be possible. The network is small ish but there is no IT profesionals on site ha ha. The techs know how to use spanners and screwdrivers so changing a SD card might be a bit too much, lol.

LMAO, Cheers Nak B)

Posted by ash on 20 July 2012 - 09:35 AM in Netduino Plus 2 (and Netduino Plus 1)

i just did this:

            DirectoryInfo dirinfo = new DirectoryInfo(@"\SD\Bin");
            if (dirinfo.Exists)
                GotSDCard = true;

:lol:



#32787 Take a dirty picture for me

Posted by ash on 27 July 2012 - 11:47 AM in Netduino Plus 2 (and Netduino Plus 1)

sorry, the topic is not going to be that interesting. :lol: I've got my NP hooked up to a serial camera and i want to take a pic and then push it on a webserver. By the looks of it im getting a outofmemory exception. Is there any efficient way of do this with out using lots of memory?



#33014 dynamically loading assemblies

Posted by ash on 02 August 2012 - 11:14 AM in Netduino Plus 2 (and Netduino Plus 1)

I'm trying to do the above. it was working ages ago but now all of a sudden my app just hangs!

            byte[] assemblyData = GotSDCard ? File.ReadAllBytes(filename) : ServerHelper.DownloadFile(filename);
            if (assemblyData == null)
                throw new Exception("Assembly was empty");
            try
            {
                Assembly assm = Assembly.Load(assemblyData);
                Debug.Print("loaded Assembly: " + filename);

it hangs on the Assembly.Load call.

In the output window i get

The debugging target runtime is loading the application assemblies and starting execution.
'Microsoft.SPOT.Debugger.CorDebug.dll' (Managed): Loaded 'C:\Program Files (x86)\Secret Labs\Netduino SDK\Assemblies\v4.2\le\SecretLabs.NETMF.Hardware.NetduinoPlus.dll', Symbols loaded.

How can i fix this or see whats going on?



#33017 dynamically loading assemblies

Posted by ash on 02 August 2012 - 12:12 PM in Netduino Plus 2 (and Netduino Plus 1)

Thats what I've used but like i said it hangs on the assembly.load and does not return my app just hangs



#33020 dynamically loading assemblies

Posted by ash on 02 August 2012 - 12:43 PM in Netduino Plus 2 (and Netduino Plus 1)

its the same size and im using the little endian file. it wont even load it from the sd card if i manually copied the pe file. :(



#33022 dynamically loading assemblies

Posted by ash on 02 August 2012 - 01:22 PM in Netduino Plus 2 (and Netduino Plus 1)

would love to but it's a commerical project. I'm scrapping this now as I've spent too much time on it. Just wish this device could do OTA updates. Now got to work on a RS422 interface B)



#33024 dynamically loading assemblies

Posted by ash on 02 August 2012 - 03:58 PM in Netduino Plus 2 (and Netduino Plus 1)

we could have 100 of these suckers attached to a webserver and it would be nice if the webserver pushed the firmware update.

Posted by ash on 14 August 2012 - 01:47 PM in General Discussion
