Hello Everyone, I am stuck in a problem . The Blynk is not sending the data to the server. Here are few observations…
The first time it goes into the sendd function, It wait for 5-10 sencond and then it comes out without sending data to server Although it prints the last line also.
It goes one time in the Loop ,and then it always runs in the camCB class.
It was working fine a few days ago.
It is importent to use the camCB class for my furthur project. so can somone please help me to resolve the issue.
It also prints Login Timeout after some time in my serial moniter

You need to start by removing all the delay() commands from your code.
I would also help your debugging if you made your serial print commands more sensible, by adding-in the values of the variables that you’re sending to Blynk.
Is your device online?
How have you configured your datastreams?
What hardware are you using?
I have removed all the delay. except one in camCB class of 500ms.
No, It getting offline .
I am using a Spresense Main board and Extension Board connect with ESP8266.
Here is the Serialprint report

This thing get repeated for 5 second untill My first send data call is made.(Device is online untill this).
You need to remove this from your CamCB() function.
When you paste serial output please copy and paste the text and use triple backticks at the beginning and end, the same was you do when posting code.
Please don’t post screenshots of your serial output.
I have removed the timer.run(); function but the error is still the same.
I am attaching the full Serial output

@FNSPH your code is posted without the necessary triple backticks at the beginning and end, so it doesn’t display correctly.
In addition, you’ve hijacked a post about an unrelated topic rather than creating a new post and providing all of the necessary background information.
As a result, I’ve deleted your post.
Please create a new “Need help with my project” topic and carefully read the guidance information that appears when you do this, and provide the requested information, and follow the example about how to post code correctly.
