Sync failed ESP8266 MOD [SOLVED]

[Javier Rementeria]

Good night ,

My name is Javier Rementeria,

I have arduino connected with ethernet shield and working properly but I want to change it by module ESP8266 MOD.
I have loaded the firmware according to the video tutorial (attached photos 2,3 and 4 ), I think correctly.
When i connect the module to the IDE and go to the serial monitor, the attached result appears (Photo 1).
My problem is that when I connect it to the Level converter MH module and to arduino and load the mqtt test code, it gives me an error (sync failed).
I changed the apikey that I had running with the ethernet shield.
Do you know what can be wrong?

Hi!

Welcome Javier!

In latest version of Ferduino and test code the baud rate is 9600 as you can see here:

https://github.com/FernandoGarcia/Ferdu ... t.ino#L118

https://github.com/FernandoGarcia/Ferdu ... p.ino#L162

Change the value in uC console in ESP-link interface.

All other settings seems right.

Best regards.

Hi Fernando ,

Thanks for the reply,

I changed the value in uC console in ESP-link interface to 9600 but it still gives sync failed when a tried with de example.
Attached photos
Do i have to turn off UART debug log
in ESP-link interface too?
Do i have to replace SoftwareSerial library?
I have tried everything but still giving error. Sorry but I dont know what to do.

After change to 9600, the serial monitor show my sync failed again and i´d tried the other option but nothing changed.

Thanks for the help

Hi!

All settings are ok it should be a hardware problem.

Check the circuit.

Best regards.

Hi,
Indeed Fernando,
I have changed the voltage reduction module and it works.

Thanks for everything again
