Main loop still not working !!!

[Quikdav 15]

Hi all

I tried to use main loop (I know it does not work very well) but nothing has changed. I just want to request an external card. Here is my code. It works well but crash after a few time !!!

Please login or register to see this code.

When I run the debug mode, here is the error message !!

Please login or register to see this code.

Line 4 is empty and it work during some hours so I don't understand why it crashed suddenly !!!

I have a proposition for fibaro team. A fine way to manage main loop could be to have same parameters as for a Unix cron.

Because main loop is execute each 3 seconds by default, we need to add sleep command to control duration !!! I think it is the reason of the crash

So according to me, a best way would be to add same parameters as a Unix cron

What do you think ??

Thanks

It is a problem with json libray,

Put your code in a button, and call it for main loop.

Shad, not with json library but with data what it's get, you should never send nill to parse, every code with crash on that

What do you mean with a problem with the json !!!!

I would like to avoid to use button. It is the workaround I used before.. I used a scene triggered each 10 s calling a button in which I set global variable but I wanted to drop this solution

Socha : What do you mean ? what can I do to avoid that ?

What do you think about my proposition to configure main loop ?

Thanks

after that line check status and errorCode and later for sure check is response is not nill then it will work

Your device on the other end fails to send the requested json, so hc2 receives an empty response, when you try to parse it, it fails as you can't parse an empty string.

What you could try is something like this:

That way, it won't try to parse an empty string.

I think the HC2 lacks proper error handling as ther is no onError function to keep your loop going. It will simply crash if it runs into an error. So in case you have a big code and it runs into a small hickup, it will just terminate the entire code and that is an issue if your scene is supposed to stop a water pump or turn off an electric heater for instance. So proper error handling would be really nice.

MAybe the error message is not very appropriate regarding my error...

Thanks

It doesn't works even when I take into account all your remarks

About a few minutes or hours, "status" is empty. I don't receive any return code from "HC2:GET" function !!!

I just need to save the device and it restart !!!
