Get Server status and restart #47

Closed moebius911 closed 5 years ago

moebius911 commented 5 years ago

Hello

currently i use the function "server.begin ()" to launch the web server on my arduino and it works very well. However I noticed that after several wifi disconnection the server ended up crashing. My problem is that I do not see any function to obtain the state of the server or to restart it. Do you have a solution to offer me?

Hi @moebius911,

Do you have some steps to reproduce the "I noticed that after several wifi disconnection the server ended up crashing" condition?

moebius911 commented 5 years ago 

here is a piece of my program that I have simplified. the server crash after about 10min

#include <avr/interrupt.h>      // library for interrupts handling

Hi @moebius911 i had try your code and reproduced the issue, on my case happen that after the the first re connection the server was not able to response. There is a server.status() API that return if there are sockets opened or not, to restart on this case the only way is use again the begin, but you have to be sure about the connection, sometimes i had see the status function return 0 that means not-connected. I have modified your sketch in order to:

Could you test and let me know if works on your side?

pozoo commented 5 years ago

I have a similar problem: I am also using WifiNina on Arduino MKR1010 to run a simple web server. For the first couple of minutes everything works fine. The the server simply stops responding, all requests just time out. I can still ping the device. The call: WiFiClient client = webServer.available(); simply does not seem to return any clients anymore.

Any idea how to make it respond again?

Rocketct commented 5 years ago

Hi @pozoo could you share a simplified version of your sketch to reproduce the error?

Thank you for your help, my program now seems stable bye
