wifi lost firmware?

[Nuno Leitao]

Hello guys

Yesterday I wanted to raise the charge current from my evse and, as usual, I went to the web interface but couldn't find the website and ip search also not found the device in the network, so I went physically to the evse to find all ok, except in the menu, was a message to the default SSID and default password.

after looking in my phone to re-setup the wifi, I couldn't find the SSID, even at 40cm of it. However, I found a "suspicious" SSID ESP_0AA71A; never saw this before and it was showing full wifi strength.

It seems to me, the wifi board lost its firmware.

Now, I have 3 questions if you guys can point me in the right direction.
1- is there a tutorial on how to flash it without a web interface?
2- is there a wired ethernet card for openevse?
3- Can I be wrong and this is a completely different issue? The EVSE continues to work as intended, and to be honest, it was many months ago I tried to access the EVSE interface.

Best regards, 

Nuno

Have you tried just connecting to the “suspicious” AP? Maybe the firmware is still loaded, but somehow, the AP SSID got corrupted

Tried yesterday.

Refused connection...

Does someone knows what I need to do to reprogram this?

If you’re using the 8266-based adapter, you can get the firmware here:

https://github.com/OpenEVSE/ESP8266_WiFi_v2.x

 

latest release is here, if you don’t want to have to compile it

https://github.com/OpenEVSE/ESP8266_WiFi_v2.x/releases/tag/2.9.1

 

to install firmware.bin, you need to get a program that can load it in.. like esptool.py, for instance

https://nodemcu.readthedocs.io/en/latest/flash/

 

I wish one of the dev team would jump in. I haven’t done it in a while, so if I try to walk you through, I might make mistakes.

Anway, if you get esptool.py  set up, I can try to give you a command line to use

All right, this morning I came back to this project. 

Thank you a lot with your help.

Now I was able to identify my Wi-Fi card, it's an ESP8266 Huzzah ESP-12.
Bought an FTDI cable, followed this Adafruit tutorial, and I'm able to make the LED blink.

Now the issue comes when I try to upload the EVSE firmware.

I downloaded the ESP8266_WiFi_v2.x-master.zip from Github, extracted it to a folder and inside folder src I found the file src.ino
Opened again arduino ide, opened this file src.ino and when I press upload, I get this error message:

Arduino: 1.8.19 (Windows 10), Board: "Adafruit Feather HUZZAH ESP8266, 80 MHz, Flash, Disabled (new aborts on oom), Disabled, All SSL ciphers (most compatible), 32KB cache + 32KB IRAM (balanced), Use pgm_read macros for IRAM/PROGMEM, 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200"
Multiple libraries were found for "ArduinoOTA.h"
In file included from C:\Users\nunol\Desktop\ESP8266_WiFi_v2.x-master\src\src.ino:33:
 Used: C:\Users\nunol\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.0.2\libraries\ArduinoOTA
web_server.h:5:10: fatal error: ESPAsyncTCP.h: No such file or directory
 Not used: C:\Users\nunol\Documents\Arduino\libraries\ArduinoOTA
    5 | #include <ESPAsyncTCP.h>
      |          ^~~~~~~~~~~~~~~
compilation terminated.
exit status 1
ESPAsyncTCP.h: No such file or directory

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

If I go to tools -> manage libraries and search for "ESPAsyncTCP" I get ASyncHTTPRequest_Generic in return.
Click install the latest version, I let him do his thing, close the program, and open it back.

Click upload and I always get the same error.

So, I'm missing something...
Any ideas here? I'm here for sure, for more than 6 hours, and can't get out of here...

Best regards and thank you in advance for any pointer

And then, it seems I found the way.

Used NodeMCU-PyFlasher to flash the pre compiled firmware.bin and I already have a wifi network.

Either way, thank you !!!
