FIXING VEVOR 3018 VIGOSTICK OFFLINE CONTROLLER

It's dead Jim!

image

For some unknown reason a couple of vigotec offline controllers (VigoStick) from our VEVOR 3018 farm stopped working with a blank screen of death.

image

Let's find out what makes it tick

First thing was to try to reverse engineer the pins that had no name in the bottom of the controller, turns out these are the UART0 that can be used to upload sketches to the ESP32.

image

Then i followed the LCD pins to map out the GPIOs that controlled the SPI ST7735 1.8 inch screen that vigostick is using:

  • TFT_CS 15, TFT_RST 2, TFT_DC 12, TFT_SCLK 13, TFT_MOSI 14

image image

Lets install a LCD library and see if things works with a new firmware

Installed Adafruit_ST7735 library in arduino IDE and used the inbuilt graphics text example modifying the following code to align with the pinouts

#else
  // For the breakout board, you can use any 2 or 3 pins.
  // These pins will also work for the 1.8" TFT shield.
  #define TFT_CS        15
  #define TFT_RST       2 // Or set to -1 and connect to Arduino RESET pin
  #define TFT_DC        12
  #define TFT_SCLK      13
  #define TFT_MOSI      14
  
  ...
  
  // For ST7735-based displays, we will use this call
  Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);
  
  ...
  // (This one also works but with glitches on the edge of the screen)
  // Use this initializer if using a 1.8" TFT screen: 
  // tft.initR(INITR_BLACKTAB);      // Init ST7735S chip, black tab
  
  // OR use this initializer if using a 1.8" TFT screen with offset such as WaveShare:
  tft.initR(INITR_GREENTAB);      // Init ST7735S chip, green tab

To upload the code there is a trick that one must do when the program tries to connect to the serial and that is to short the GPIO0 to ground to put the ESP32 in boot mode, in case of the ESP32-WROOM-32E it is the farthest pinst to the right of the chip like in the picture

It kind of works... butt

Ok so the ESP is working and the LCD is fine... something else is messed up

vevor_vigotec_vigostick

A couple of websearches and found a video explaining how to use arduino idea to backup and restore a flash image on a esp32, a tool called esptool that is well documented. So next thing was to try copying the code from a working ESP and injecting it to the vigotec to see if it worked.

How to Backup & Restore Official Firmware on any Espressif ESP8266 & ESP32

Using ESPTOOL

  # IINSTALL ESPTOOL
  pip install esptool
  
  # RUN ESPTOOL
  esptool.py
  
  # Change COM3 to your own Port

  ## For  1M Flash:
  python esptool.py -b 115200 --port COM3 read_flash 0x000000 0x100000 flash_1M.bin 
  python esptool.py -b 115200 --port COM3 write_flash --flash_freq 80m 0x000000 flash_1M.bin 

  ## For  4M Flash:
  python esptool.py -b 115200 --port COM3 read_flash 0x00000 0x400000 flash_4M.bin
  python esptool.py -b 115200 --port COM3 write_flash --flash_freq 80m 0x000000 flash_4M.bin
  that is all
  
  ## Erasing Flash
  esptool.py -b 115200 --port COM7 erase_flash
  
  you should get something like this for the 4M flash

The cloning worked for the graphic demo but when i cloned a working vigostick to the non working one the blank screen returned... What now? I opened the binary file that i had just backed up in HxD to see if the file was encripted and it does not seem so, since there is unencripted text showing including M and G commands

image

Slap in the forehead!

Turns out i had not power cycled the ESP properly, so the cloning works but now this error:

    Fatal Error
    VigoStick 1.32 211123
    Run Error!

image

Go deep into the rabbit hole...

My next guess is that the eeprom, that holds the webfiles is corrupted or mismatched, maybe filesystem upload is missing or maybe i messed up the memory size on the backup ???

Ok so dropping the image into a wemos with a similar EPS32-WROOM-32E chip and having easy acess to the enable button mi managed to get this debug list on the arduino serial monitor...

So the error is most likely just the fact that there is no GRBL board since the ESP is creating the Access Point and the control page can be accessed via the IP/Password that the serial dump shows.

So most likely this is done and fixed. I should probably extract the 1.5v from the newer controller if the error is the board connections, since the newer version handles that error more greacefully allowing full controll of the standalone controller instead of showing a blocking error like this version does :)

Nope!

... It was not. I am out of ideas for a couple of days

Lateral thinking and a new approach finally fixed it

So seems the cloning is missing some thing, well these stick supposedly upgrade Over The Air (OTA) so i got inside the webpage, added the network credentials, it rebooted and then i was able to check for updates...

image

After issuing the upgrade command and being greeted with the Update message on the ESP screen i waited for it to "UPDRADE..." as seen in the picture :P

image image

It rebooted and it was working... probably china also has my gues wifi password now :P I'll just make a honeypot full of wasps out of it, just in case...

image image

Either way it is fixed and hopefully it will help someone in a near future Last but not least, popped up inside the VigoStick portal one last time to change back the wifi ID and password. I dont want these things connected to the web nor i want everyone that can boot a machine to read my guest wifi and password at the boot screen so i used that to send a subliminal message

🧔: How do I capture and backup an OTA update on an ESP32?

🤖: To capture and backup an OTA update on an ESP32, you can follow these general steps:

  1. Set up an OTA server: First, you need to set up an OTA server that will serve the firmware updates to the ESP32 devices. You can use platforms like ArduinoOTA or your custom server implementation.

  2. Prepare your ESP32: Make sure your ESP32 is properly set up for OTA updates. This involves configuring the network connection and enabling OTA updates in your code.

  3. Capture the OTA update: Once your ESP32 is connected to the network and set up for OTA updates, you can capture the update by intercepting the network traffic. One common method is to use a packet capture tool like Wireshark.

    a. Install and open Wireshark on a computer connected to the same network as your ESP32.
    b. Set up a filter to capture the network traffic from the ESP32. For example, you can filter by the IP address of the ESP32.
    c. Initiate an OTA update from your ESP32.
    d. Monitor the network traffic in Wireshark, and you should be able to capture the firmware update file.

  4. Backup the OTA update: Once you have captured the OTA update file, you can save it as a backup for future use. You can save it on your computer or in cloud storage.

It's important to note that capturing OTA updates should be done for legitimate purposes, such as backup or analysis, and should not be used for any unauthorized activities or copyright infringement. Make sure to comply with any licensing or legal requirements associated with the OTA update you capture.

🧔: Is there a way to capture it directly inside the ESP32 by creating a program that requests the OTA but does not install it, something one can download via a web portal on the ESP32?

🤖: Yes, it is possible to capture an OTA update directly inside the ESP32 without installing it by creating a program that requests the update but saves it instead of applying it immediately. You can achieve this by implementing a custom web portal on the ESP32 that allows you to download the update file.

Here's a high-level overview of the steps involved:

  1. Set up a web server: Implement a simple web server on the ESP32 that serves a web page with a download link for the OTA update file. You can use libraries like ESPAsyncWebServer or WebServer to handle the web server functionality.

  2. Handle the OTA request: When the user clicks the download link on the web page, the ESP32 should initiate an OTA update request to the OTA server. To achieve this, you can make an HTTP request to the OTA server's URL using the appropriate library, such as ESPAsyncHTTPClient or HTTPClient. This request should retrieve the firmware update file from the OTA server.

  3. Save the OTA update file: Once you receive the OTA update file from the OTA server, you can save it to the ESP32's file system, such as SPIFFS or SD card. This allows you to store the update file for backup or later installation.

  4. Provide download link: After saving the OTA update file, update the web page on the ESP32 to provide a download link for the saved update file. This allows you to access and download the captured OTA update file directly from the ESP32.

By following this approach, you can create a program on the ESP32 that requests OTA updates from the OTA server but saves them locally instead of applying them immediately.

🧔: Can you write me the code for such a portal?

🤖: Certainly! Here's an example code for creating a web

portal on the ESP32 that allows you to capture and download OTA update files:

#include <WiFi.h>
#include <ESPAsyncWebServer.h>
#include <HTTPClient.h>

const char* ssid = "YourNetworkSSID";
const char* password = "YourNetworkPassword";

AsyncWebServer server(80);

void setup() {
  Serial.begin(115200);

  // Connect to Wi-Fi
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }

  Serial.println("Connected to WiFi");

  // Initialize web server
  server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){
    String html = "<html><body>";
    html += "<h1>OTA Update Portal</h1>";
    html += "<a href=\"/update\">Capture OTA Update</a>";
    html += "</body></html>";
    request->send(200, "text/html", html);
  });

  server.on("/update", HTTP_GET, [](AsyncWebServerRequest *request){
    // Perform OTA update request
    HTTPClient client;
    client.begin("http://your-ota-server.com/firmware.bin"); // Replace with your OTA server URL
    int httpCode = client.GET();
    if (httpCode == HTTP_CODE_OK) {
      // Save OTA update file
      File updateFile = SPIFFS.open("/firmware.bin", FILE_WRITE); // Replace with your preferred file system
      if (updateFile) {
        client.writeToStream(&updateFile);
        updateFile.close();
        request->send(200, "text/plain", "OTA update captured and saved");
      } else {
        request->send(500, "text/plain", "Failed to save OTA update");
      }
    } else {
      request->send(500, "text/plain", "Failed to fetch OTA update");
    }
    client.end();
  });

  server.begin();
}

void loop() {
  // Handle incoming client requests
  server.handleClient();
}

Make sure to replace "YourNetworkSSID" and "YourNetworkPassword" with the appropriate credentials for your Wi-Fi network. Also, update the OTA server URL in the client.begin() function within the /update route.

The code sets up a web server on port 80 and defines two routes: / and /update. The root route displays a basic HTML page with a link to the /update route. When you click the link, it triggers an OTA update request to the specified OTA server URL. The received OTA update file is saved as "firmware.bin" (you can change the name) in the preferred file system, such as SPIFFS or SD card.

Please note that this is a basic example, and you may need to modify it according to your specific requirements and use appropriate libraries for file system access and OTA updates based on your chosen hardware and frameworks.

I am not sharing it with you lol... there is no @ in that reply/post

I also dont understand what you mean... The AI response is real, now if what is suggested is crap... that is very likely true.

@luisfcorreia thanks for the suggestion was not aware of mitmproxy.
I presume it will work like wireshark i still need a pc with dual wifi or a wifi and a cable to serve the web to the ESP right?

@luisfcorreia for some reason the dam things do not want to connect to any of my pc hotspots...

@X3msnake you need me to come over with a Linux laptop?

now please explain how are you setting up that hotspot

@luisfcorreia found the bug using a router. dam things only accept 2.4Ghz and must be the old WPA protocol. and that cannot be set on the Windows hotspot feature. i will connect the router bridge to the pc hotspot and the esps to the router 😸
