Connect nodemcu to a wifi network using blynk

Need Help With My Project
27

@Gunner I believe buy is actually but.

28

I thought so as well ;), but covered both contingencies as it seems (to me) that WiFi Provisioning is geared toward the publishing of Apps.

@suhanichandrag, you have already posted the same message 4 times in this topic!

if you assume that people on this forum are affected by alzheimer’s disease, then why do you think they could help you with technical questions?

and beside posting the same thing over and over again, you never bothered to give those details costas asked. with this attitude do no expect much help on this forum…

please send me your mail id so that i can send you the link.

Just sent it to you via PM.

@suhanichandrag please see provisioning thread at Blynk Provisioning fails with Arduino Core Master Branch

Which version of the core are you using? I am guessing 2.3.0.

From the details you sent me it looks like you are using the myPlant provisioning. You should switch to the Template_ESP8266 found in your IDE as I believe it has a few subtle differences to the myPlant sketch.

Start with a new project, just a single button on V0 and everything set at NCODEMCU including the sketch edit shown below.

//#define USE_SPARKFUN_BLYNK_BOARD    // Uncomment the board you are using
#define USE_NODE_MCU_BOARD            // Comment out the boards you are not using

Please provide Serial Monitor data when you switch to the Template_ESP8266.

33

If you are using 2.4.0-rc1 you will need to switch back to 2.3.0.

34

@suhanichandrag you don’t have to roll back to ESP8266 Arduino 2.3.0 if you are using a later version. You can make a minor library change as referenced in the last url I posted in this thread. See if that fixes your problem.

35

http://esp8266.github.io/Arduino/versions/2.3.0/doc/installing.html
I have followed all what is given in the above link to install 2.3.0 version, but still it gives the same problem
Could youll help me?

36

And i have selected the board to be nodemcu1.0 and nodemcu 0.9, both cases give the same problem

37

Send me another PM of the Serial Monitor output when you try to provision using 2.3.0 core.

38

From the screenshot you sent the last entry states “Configuration stored to flash” which is what you need.

Is your MCU provisioned correctly now?

For reference you can simply cut and paste the Serial Monitor data into a Blynk PM, it doesn’t need to be a screenshot.

39

How do i check if my MCU is provisioned correctly

40

It will be connected to the Blynk cloud server i.e. be online.

Is it online in My Apps?

Also if you press reset on the MCU it will connect to server rather than create the Access Point etc.

41

Yes the device is online

42

Then you have successfully provisioned your MCU for use with Blynk.

Have you tried resetting the MCU to ensure it stays online and PM the Serial Monitor data to me one last time?

44

Then what might be the reasons for the connectivity issue and how do i solve that

45

yes after resetting MCU also, the device gets online.
Sure ill send you the serial monitor data

46

Would it be because of the publishing ssue?
I have not published my app yet? I seem to face this problem in the preview stage
