Edgent_ESP32 example not connecting to Blynk with error

[nhuythuy]

As mentioned above. I could see the message showing that the BOOT button has been pressed when I tried to clear previous Wifi setting (I tried and it worked with Blynk 1.0.0).

But then after successfully reset my Wifi setting, I cannot provide Wifi credentials with error message posted. I also cannot see any message if I press BOOT button now, I guess the message would only appear if it has been successfully saved with Wifi credentials.

FYI.: I have used the same Wifi credentials for more than a year. My NodeMcu board works fine with Blynk

I think you’ll find that making this change…

@nhuythuy

I have uncomment my board (in Adgent_ESP32.ino) as below:

// Uncomment your board, or configure a custom board in Settings.h
#define USE_WROVER_BOARD
//#define USE_TTGO_T7

without fully understand that you aren’t using a WROVER board, and even if you were, the pin assignments may be different, has caused the button to stop working, because as I said previously…

@PeteKnight

I seriously doubt if your board has this configuration.

Your first step has to be to understand your board settings, and have a Settings.h configuration that matches that.
Only then will you be able to know that you’ve cleared the stored settings, and that the board is in the correct mode to be provisioned.

Pete.

Thanks, I will go through it one more time

[nhuythuy]

This is my ESP32 board (ESP-WROOM-32) while waiting for config.: Blynk esp32 failed to assign wifi credentials - YouTube, same example uploaded

It is blinking and I tried again with my Wifi SSID and password. I got the same error as above (after failure, it reset itself and ask for configuration):

That’s all very interesting, but once again, you aren’t addressing the issues that I’ve said you need to focus on.

It would also be a good idea to shorten your device name in the template, then update your sketch accordingly, as this SSID is quite long…

BasementESP32

My App ID is only “BasementESP32”, but Blynk added it automatically.

I have tried with another Blynk example: ESP32_WiFi, this worked just fine for me for 541 minutes then stuck (frozen, I think) Even if I tried to use watchdog to reset but it did not help. Could this be my ESP32 board issue? I have two boards, it seems to behavior in the same way.

[PeteKnight]

@nhuythuy

Yes, I know that.

I’m going to take a step back from this topic, as you don’t seem to be interested in doing the things I suggest.

Pete.

[nhuythuy]

I should have some freedom to investigate around, try with different possibilities in stead of just wait and follow your instructions :). Different tries did not give me better result so I did not care to post it here to mess up the topic.

The only suggestion I have not tried was having a shorter AP SSID, if I remember correctly. And yes, I have just done that (#define BLYNK_DEVICE_NAME “BMx”) with same error happened (as console log below).

@nhuythuy

You have as much freedom as you want, but as far as I’m aware from your feedback, you still haven’t sorted-out the pin assignments in Settings.h and provided serial output which shows that the button is responding correctly and allowing you to clear the saved credentials.
That’s despite me asking you to do this on multiple occasions.
So I’d rather spend my time helping community members who are interested in doing the things I ask them to, and feeding back with the results.

Good luck with your project.

Pete.

[nhuythuy]

Thanks a lot for your help so far. Really appreciate that.

I understood that you are supporting many topic so I have explained twice the reason that I could not provide serial output when I push BOOT button any longer since I did push BOOT button but nothing different as the log I posted (after I have reset esp32 with esptool). I have seen another message showing that I did push BOOT button but only before I erased my esp32 (I could input credentials using Blynk 1.0.0 before). The reason for not showing anything different could be that my esp32 has not accepted credentials so it does not show any info. when I pust BOOT button.

Regarding pin assignment, I have mentioned that I am using ESP-WROOM-32. I thought that I have posted this clip: Blynk esp32 failed to assign wifi credentials - YouTube, 3 days ago in this thread.

Anyway, I am ok with esp8266 Blynk and will come back with ESP32 later.

Once again, many thanks

Thuy

@nhuythuy

I also cannot see any message if I press BOOT button now, I guess the message would only appear if it has been successfully saved with Wifi credentials.

@nhuythuy

You are making an incorrect assumption about the button press having no effect when there are no stored credentials.

If you do not see this message in your serial monitor when you press the button…

Hold the button for 10 seconds to reset configuration...

then your pin assignment is incorrect. Until you solve this issue you will not make any progress with your problem.

I would you suggest that you read this…

Troubleshooting Edgent Dynamic Provisioning Problems

There seems to quite a bit of confusion about how the dynamic provisioning process works in the Edgent sketch examples, and how to re-provision a device with new WiFi credentials. Many people omit to configure the board type correctly in the sketch, and this also causes problems. Here’s a guide to how the process works, and the things to watch out for… Overview You start by creating a template, preferably in the web console (https://blynk.cloud/) This gives you the BLYNK_TEMPLATE_ID and BLYNK…

and make the appropriate changes to your pin assignments.
