Any Suggestions ??

Hi Hathout,

Do you have an estimated time for the delays in your application?

What is the output of running uname –a?

Are you just running this application in your board?

Are you sure this is not an issue with the network itself?

I suggest you to debug your code to check the delays you are getting between the requests to the server. You can also try to edit your code in order to be modular and not a sequence

Regards,

Charlie

It was a networking issue

Hi Hathout,

Do you have updates in this?

Have you been able to debug your code?

Regards,

Charlie
