[font="arial, helvetica, sans-serif;"][color=rgb(34,34,34);]I am running a web server on NP2 (previously on NP1) and it seems to run ok.[/color][/font]
[font="arial, helvetica, sans-serif;"][color=rgb(34,34,34);]The problem is, when I start pushing it - a little too much processing for each received message combined with hysterical pushing the refresh button on the browser (more than 4 times in Debug mode - a little more en Release mode) - it falls over!.[/color][/font]

I have tried this, but I still have problems. It gives me however et better control of what happens.
The Socket.Accept falls over when it has more than 3 outstanding messages. It then fires a socket excepton but it is not caught by the try-catch.
Because of this, the thread never dies and the clean-up wil not remove the thread from the array.
I cannot see how I can stop the socket from accepting messages.
This is odd!

I have the same problem - is it a v4.2 problem? I cannot get it to accept "IntegratedSocket".
I installed toolbox,
included Toolbox.NETMF.NET.SMTP_Client
using Toolbox.NETMF.NET;

#41656 NP2 OneWire problem

Netduino Plus 2 (and Netduino Plus 1)
I converted my house-control application from NP to NP2 including moving from CW2's wonderful One wire implementation (FW 4.1) to the new standard NETMF One wire implementation. Everything worked in the test configuration, but when I exchanged the board in the 'real' configuration, One Wire did not Work.
I am using GPIO 13 for One wire and using a pull up of 1.8K. This was ok with NP but not with NP2.
Is there a difference between the two hardware interfaces? - Any advices?
Well - I could do some tests with various resistors, but the distance between the test bench and my 'real' implementation is 150 miles, so I need to do it right Next time!

Does the 4.3 implementation support OneWire?
Will the Gen.1 implementation of 4.3 support OneWire?
Netduino has been ignoring OneWire allthough it is an essential part of NETMF and should not be negleted.
The argument of saving flash/ram is like removing the wheels from a car beause they take up too much space!
I am a litle (very) frustrated waiting for OneWire on 4.2, Gen.1.

Onewire support is also available on NETMF 4.2 through ToniA's firmware here:
There was a problem deploying large software because the watchdog interupted the deploy. ToniA is looking into it and right now I am using the original boot-loader wihich disables the watchdog.

Netduino Plus 2 (and Netduino Plus 1)
For reference - her is my OneWire Engine using Netduino Plus 2 and native OneWire. (it may not run without modifications as it is part of my home automation controller.).
The engine runs in a loop and maintain 2 tables - one for DS1820 and one for DS2438 as these are the once i use.
All use of the data from the devices, are retrieved from these tables.
I have used a similar module on Netduino Plus (ver.1) but with the use of CW2's implementation of OneWire. This requires the special firmware and is only availalbe on NETMF 4.1.

Your meaning on "watchdog" may be more complicated than mine, but this is how I do it - the simple way:
The watchdogdelay (wDelay) is her set to 12 hours (100*60*60*12 miliseconds).
The Reset() command sits in a place I want to make sure that I excecute within the 12 hours, and it resets the wDelay counter.
On timeout (_TimerTick) the watchdog write a message to my log, and reboot the device. Simple but effective.

public static class WatchDog
{
const Int32 wdDelay = 1000*60*60*12;
static Timer wdtimer = new Timer(on_TimerTick, null, wdDelay, 0);

{
wdtimer.Change(wdDelay, 0);
}
static void on_TimerTick(Object state)
{
CLog.LogEvent("Watchdog Rebooting.");
PowerState.RebootDevice(false, 1000);

I am not sure if the same issue is occurring that I had on my project but I was getting the same error message writing to the SD card.
In my project I have 6 sensors that are being polled up to 3 times a second then that data is written to 6 different log files using the same basic method as you.
I was getting this same error and it was due to trying to write the data too fast (or I assume that was the case). So I put a few Thread.Sleep(1) or Thread.Sleep(10) in certain places to allow for catch up and completion of the file create/close and write/close. This worked and it has never thrown an error again after running hundreds of hours now.
Thanks Dave - I tried this but with no luck.

Thanks for quick reply Stefan and Chris
I am now using NetduinoPlus_v4.1.1_beta1_CW.NETMF.OneWire-1.0.5.0
I was having problem with I2C because of som problem in firmware but this may have been with 4.1.0-6 - I gave up on I2C because of that.
Now I have probems with StreamWriter.
This is the Code:
ways to (partly) deal with the problem are:
- spreading "Debug.GC(true);" all over the place in rich quanities.
- NOT making small chunks of date to write, but puttin everything in one string!!!
I can make a small program with only read and write of the file, and it will usually work but as soon as I add other code to it, problems begin.

I find CW2's implementation very reliable. I use a digital port directly with a 1K8 resister to +5V - it drives about 5 meter with many drops and no problems.
Implementing One-wire devices is not dificult.

Sorry to be a bit negative.
My previous exitement for NetduinoPlus has slowly turned into a lot of frustrations.
I may be stupid, but I based my project on Onewire, and maybe I am the only one left en the world using it.
After asking around a lot in the forum, I found CW2's very nice implementation which I still use with Firmware version 4.1.1.
4.1 had other problems (OutOfMemoryExeption in Stremwriter) and I have been looking forward to version 4.2 in the hope that this problem was solved. I was promised that there would be a 'speciaol verion' of 4.2 with onewire support, but after the introduction of NetduinoGo, it looks like no one cares about NetduionoPlus anymore.
I am about to give up on this forum. My requests are no more answered and it is not even possible to find them searching my own comments (sometime I can find them by searching specific text).
It is not my intention to be destructive, but I think my life with NetduinoPlus is running into a deadend.

I have no doubt about the good realization of CW2, nor in your bona-fide...the problem is exactly what you write: the impedance is not balanced, thus the "reliability" is just a statistical performance of your implementation.
Basically, you have just one (?) resistor as pull-up by the Netduino side (or the other).
First off, when the line is pulled down the impedance is almost zero Ohms, but when the line is left floating the actual impedance is 1.8k.
Secondly, probably your 5mt wiring is short enough to avoid reflections, otherwise an high-impedance (by the device side) would have a mirror-effect for the high frequencies. You know, any edgy wave is composed as very high frequencies.
Thirdly, I suppose your wiring is a shielded cable, or either your wires run along a noiseless environment. If not, your signal would be plenty of undesired noise, spikes, and whatever else.
It's just a clarification, because many users are asking that, but the long wiring is often an hard task to solve.

Hi
I use a socket-based server and get the same problem. It is very easy to reproduce. Just hit the F5 on the browser a couple of times and you get the Socket Exception.
With the socket-based server, it looks like it recovers after the exception - I have not tried it for a long perode of time yet.
This is what it looks like:
The latest change I made was to move the statement "_socket.Listen(10);" from the sub HttpSession() to the sub _Listen().
For some unexplainable (for me!) reasoen, it made the thing recover after the exception rather than stopping the server.
This is with 4.1 - when (if!) 4.2 is relesed and when (if!) OneWire becomes available for 4.2, I look forward to see if this has been solved in 4.2.
Regards
Erik

In debug mode everything is normal on one board - the other stops with an Error: a3000000
Resolving.Link failure: some assembly references cannot be resolved!!Assembly: NewWeb (1.0.0.0) needs assembly 'SecretLabs.NETMF.Hardware.NetduinoPlus' (4.2.2.0)Error: a3000000Waiting for debug commands...The program '[2] Micro Framework application: Managed' has exited with code 0 (0x0).
What is worng?
[font="calibri;"]The problem seems to arise when the program reaches a certain size.[/font]

Netduino Plus 2 (and Netduino Plus 1)
Additional Info:
Using MFDeploy->Plug-in->Debug->Show Device Info, I get different infor for the two boards:
The good board says:

The bad board says:

The Secretlab assemblies does has not been loaded??
Another diff.:
When pressing hte Erase button in MFDeploy, the good board shows both "Deployment" and "File System". The bad board only shows "Deployment".

Thanks Chris
This is on NetduinoPlus (version 1).
As mentioned - I test with 2 identical units. One Works as expected - one fails.
The dll is available (Works with the other board).
After following your instructions (Erase, clean, build) the error changed.
There are no error en build - the error comes when running Debug in VS2012 (and VS2010).
The new Error indications is:
Cannot find any entrypoint!Done
Here comes first the full result of "ERASE" operation in MFDebug:

Netduino Plus 2 (and Netduino Plus 1)
Tnx Bi Qin but this is what I did.
For NP1 I am using TonyA's firmware here as I need OneWire. It worked for som units but not all.
I always use static IP - I set it in the program together with DNS and MAC.
Again - it works on some units - not all.

[font="calibri;"]This might be a stupid question, but I have been messing around with different versions of firmware on my devices and want to go back to start ("factory reset").[/font]
[font="calibri;"]The result is strange behavior: One NP1 will deploy a program, but ends all threads without doing anything when started.[/font]
[font="calibri;"]Both NP1 and NP2 will throw a socket exception whenever I try a DNS request for ex. “Microsoft.com”.[/font]
[font="calibri;"](This happens even with this as the only one codeline in the software:[/font]
IPEndPoint ep = new IPEndPoint(Dns.GetHostEntry("microsoft.com").AddressList[0], 80);[font="calibri;"] [/font]
Other devices - with the same IP-setting - performs well.
[font="calibri;"]Now I want to “factory reset” my devices and try all over with new firmware. I touched the blank spot and tried all the obvious ways but nothing helps. [/font]
[font="calibri;"]What can I do?[/font]
[font="calibri;"]The socket exception occurs with 4.2 as well as with 4.3 beta.[/font]
[font="calibri;"]Please advice![/font]
