Nodemcu stays in connect but it get divice offline within a day

Just search the forum for Blynk.config and Blynk.connect, or read the Legacy documentation.

PeteKnight · August 17, 2021, 8:01am

That looks better.
Now I’d add a timer that checks if the WiFi is connected, and if Blynk is connected, and if not then do a re-connection, rather than a restart like you had originally.
You should also introduce a flag so that you only send one notification for each motion detection event, to avoid spamming yourself with notifications and to avoid exceeding the 1 notification every 5 second limit.

Pete.

Sir, I cannot understand what you are saying accordin to this post.
Can you please tell in a way that i could easily understand? I really appreciate your help.

PeteKnight · August 17, 2021, 9:43am

Go back to the original code you posted.
Look at the void loop and locate the part that checks if there is a WiFi connection and restarts the device of not.

Put this on a function, remove the restart part and replace it with a reconnection call, and do the same with a check to see if Blynk is connected.
Call this function with a timer.

Pete.

No, not really, but I’m growing tired of explaining what you should do and you only taking-in part of the message.

All the information you need is in this topic, maybe you should just take the time to re-read it?

Pete.

Mohamed_Aflal · August 17, 2021, 12:59pm

Sir, I cannot understand what you were saying even if i re-read it.Will it work if i use the example sketch?. I am a beginner in coding. Early i used arduino and it worked for 6 months. After that it didnt work. Therefore, I chose nodemcu but it goes offline after 1-2 days and I looked for solution for 3 months and found none.Can you please patiently tell me how it should be done permanently?. Thank you.
