ESP8266 does not communicate with Arduino

[J-M-L]

Something that looked like that

I’m not sure you can find those anymore

That’s taken from an old French tutorial I had written a while back

Les Bases d'un Serveur Web sur ESP-01 en commande AT

EDIT: SI VOUS CHERCHEZ LE CODE IL EST DANS LE POST #10 Un petit tuto d'explication sur l'écriture d'un mini serveur web en utilisant un ESP01 connecté en mode série sur un Arduino et en utilisant le langage de commandes AT L'objet de ce post n'est pas de documenter l'ESP-01 et comment s'assurer d'avoir le bon firmware dessus. Ceci est traité ailleurs sur le web, je vous laisse explorer (perso je suis sur Mac et donc n'ai pas accès aux nombreux logiciels sous Windows permettant …

Thanks! If I buy another one, I will buy that adapter also.
However, for this one, what could I do to solve this error? I have seen that it is quite a common problem.

[J-M-L]

To be honest, I’ll put it in the trash/recycle bin…and never buy one again unless you have a solid reason for that…

get a more capable board and program directly in c++…

[hzrnbgy]

I've got good luck with these. This is an AT firmware and should work with an ESP8266-01S. Make sure you follow the memory address locations to the letter

[arturo_olvrs]

I have tried this solution and it still does not work. I believe it should not be a problem related to the firmware as I have flashed it using different ones and I still get the same error always.

@arturo_olvrs

I believe it should not be a problem related to the firmware as I have flashed it using different ones and I still get the same error always

I'm not actually sure that the flashing worked. do you get positive confirmation all went fine?
if you run this command line:
esptool.py –port COMx flash_id
(where COMx is your com port), what do you get?

[arturo_olvrs]

When I run the command you indicated me, I get this.

esptool.py v3.1
Serial port /dev/tty.usbserial-0001

OK that's a good sign that you can read and write from the ESP.

have you tried ESP8266 NONOS SDK V1.5.3 ?

[arturo_olvrs]

I have just done so, and it gives me the same error.

@J-M-L

esptool.py –port COMx flash_id

Using this command to check, it prints me the following:

esptool.py v3.1
Serial port /dev/tty.usbserial-0001

Therefore, I think I have flashed it correctly.

[J-M-L]

can you share the commands and response you see when flashing ESP8266 NONOS SDK V1.5.3?
may be it's worth erasing the flash

• power down
• connect GPIO0 to GND
• power up
• run esptool.py --port /dev/tty.usbserial-0001 erase_flash
• re-flash firmware ESP8266 NONOS SDK V1.5.3
• power down
• disconnect GPIO0 from GND
• power up

if you could share all what you see during this process in the command line or console, that would be great

--flash_freq 80m --flash_mode dio --flash_size 4MB
your module is only 1MB

can you do the following:

go download ESP8266 NONOS SDK V1.5.4 https://www.espressif.com/sites/default/files/sdks/esp8266_nonos_sdk_v1.5.4_16_05_20.zip

Unzip file file, you should see

As you have 1MB modules, the applicable upload information probably will be (form the readme)

### Flash size 8Mbit: 512KB+512KB
    boot_v1.2+.bin              0x00000
    user1.1024.new.2.bin        0x01000
    esp_init_data_default.bin   0xfc000 (optional)
    blank.bin                   0x7e000 & 0xfe000

create a directory on your desktop and copy the relevant file from the unzipped folder to your new directory (the last one is in the at/512+512 subdirectory

➜ esp8266_nonos_sdk_v1.5.4_16_05_20/ESP8266_NONOS_SDK/bin/blank.bin
➜ esp8266_nonos_sdk_v1.5.4_16_05_20/ESP8266_NONOS_SDK/bin/boot_v1.2.bin
➜ esp8266_nonos_sdk_v1.5.4_16_05_20/ESP8266_NONOS_SDK/bin/esp_init_data_default.bin
➜ esp8266_nonos_sdk_v1.5.4_16_05_20/ESP8266_NONOS_SDK/bin/at/512+512/user1.1024.new.2.bin

and

So you should have a simple directory with 4 files

in a terminal console, cd to that working directory and perform the following

• power down your ESP (disconnect)
• connect GPIO0 to GND
• power up
• run esptool.py --port /dev/tty.usbserial-0001 erase_flash
• run esptool.py --chip esp8266 --port /dev/tty.usbserial-0001 --baud 115200 write_flash 0x00000 boot_v1.2.bin 0x01000 user1.1024.new.2.bin 0xfc000 esp_init_data_default.bin 0x7e000 blank.bin 0xfe000 blank.bin
• power down
• disconnect GPIO0 from GND
• power up

can you give it a try and report back what you see?

when you connect your ESP to a Serial monitor ?

[SteveMann]

@arturo_olvrs

Related to the better ESP alternatives you use, which one would you recommend me? I am using it to display some values from a sensor in a web page using Arduino.

Whenever I see anyone trying to use an ESP as a WiFi shield for an Arduino Uno, I am reminded of the wisdom of Marvin: "This will all end in tears. I just know it".

I would recommend the Wemos D1 Mini or NodeMCU. They already have WiFi and you can run a web server directly on them.

[arturo_olvrs]

Yes. It just doesn't send anything, and it does not respond to AT Commands. When I reset it connecting RST pin to GND, it prints that error at 74880 baud.

[J-M-L]

I don't have mine anymore to try out... I would explore variations on this to see if you get lucky...
but as said before, that's already a lot of time invested in a half baked solution that will likely lead to disappointments...
