Which board are you using ?

[prai44]

esp wroom 32

[muki01]

esp wroom 32

Check the version of the board from board manager and if there is a new version update.

[muki01]

1. Which version of Arduino IDE are you using?
2. Are you sure you have selected ESP32 as the board type? If yes, which ESP32 did you choose in the IDE?

[muki01]

I test with the same stuff and it works for me. I do not know. If I find a solution, I will write to you. You can test by reinstalling the Arduino IDE and the esp32 board.

[muki01]

If you have another library for wifi in this directory 'C:\Users\USERNAME\Documents\Arduino\libraries' , folder like "Wifi" rename it like "Wifi1" or something else and test.

[muki01]

I tested in a virtual machine from scratch

1. I installed Arduino IDE 1.8.19
2. I added a link for ESP32 in Arduino IDE. https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
3. I installed ESP32 (v2.0.15) from the board manager
4. I select ESP32 Dev Module
5. I installed the ESPAsyncWebServer library from the library manager. It asked if i wanted to install AsyncTCP library as well and i clicked "install all"
6. I installed the ArduinoJson library.
7. I clicked Compile button and it didn't give me any error.

Here is all Librarys I installed Libraries.zip

You need to download my Last updates this is your problem. Download my Last commits. Open ESP32.ino file. After that you need to see 4 pages like this:

If you see these pages, then there is no problem. Press the compile button without changing the code.

[prai44]

code compile but not so starting ip rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1344 load:0x40078000,len:13964 load:0x40080400,len:3600 entry 0x400805f0 ets Jul 29 2019 12:21:46

[muki01]

if you uploaded the code successfully, you need to connect to the access point, with your phone or something else, called OBD2 Master. Then open the browser and enter the IP. Default IP for access point is 192.168.4.1

[muki01]

Does it work ?

[prai44]

peramiter set but connect phone hotspot

const char AP_ssid = "OBD2 Master"; const char AP_password = "12345678";

IPAddress AP_ip(192, 168, 53, 60); IPAddress AP_subnet(255, 255, 255, 0); IPAddress AP_gateway(192, 168, 53, 52);

[prai44]

conection not stables i have try ssd id rename

[prai44]

not connect String STA_ssid = "prince"; String STA_password = "11111111"; String IP_address = ""; String SubnetMask = ""; String Gateway = ""; String protocol = "";

[prai44]

any desk access in my laptop

[muki01]

1. If you want to change the IP address, you need to enable this line // if (WiFi.softAPConfig(AP_ip, AP_gateway, AP_subnet));
2. If the connection is not stable, you can increase the wifi power (dBm) in this line WiFi.setTxPower(WIFI_POWER_2dBm); or delete for default value. I scaled back because I'm using an ESP32 C3 Mini, it overheats a lot.

[muki01]

Do not change settings.conf file. Do not change this Strings: String STA_ssid = ""; String STA_password = ""; String IP_address = ""; String SubnetMask = ""; String Gateway = ""; String protocol = "";

ESP32 first creates an access point and his name is "OBD2 Master". You need to connect to this WiFi. If you want to connect to your WiFi connection, you can do it from the web server in settings menu.

[muki01]

If you explain better what you want, I can help you better.

[prai44]

I am not able to make the network stable, I have tried all the things which you have told, can you understand me by remote accessing my laptop or can you tell me the step to step network configuration of the code?

[muki01]

Have you uploaded the website to SPIFFS? If you have uploaded, follow these steps:

1. Don't change my code and upload it to your ESP32

2. ESP32 Creates a WiFi (access point) which you can see on the wifi page of your device.

3. You need to connect to this WiFi (access point) called "OBD2 Master". Тhe password is "12345678"

4. Then you need to open "192.168.4.1" in your browser

5. You should see this page:

6. Just ,If you want to connect your ESP32 to your home WiFi, you can do so in the settings page.

[prai44]

not show wifi ssid

[muki01]

You dont need Serial Monitor.

[prai44]

The code has been run but ssd name is obb2 master ssd is not showing in my phone.

[muki01]

The code does not print the SSID of the serial monitor. This is how you should see in your wifis.

[prai44]

not show i have allready tried

[muki01]

Delete this line and test WiFi.setTxPower(WIFI_POWER_2dBm);

[prai44]

allready check it

[muki01]

Have you uploaded data folder to SPIFFS??

[prai44]

yes

[muki01]

ANY SOLUTION

[prai44]

Not Working Tried this code many times but couldn't find solution please resolve solution

[prai44]

[muki01]

Hello. I think I found your problem. I tried with ESP32 Devkit and application gave the same error. The problem is that you shouldn't use pin 8. In the code, pin 8 is used to control an LED. Change it to some other number and try. Before, it didn't give me an error because I was using an ESP32 C3 model. ESP32 c3 and ESP32 Wroom pins are different. I think the led on devkit v1 was on pin 2. You can change 8 to 2.

[prai44]

Working fine Can data saving features be added to it?

[muki01]

I'm glad it works 😊. I may add this feature in the future.

[prai44]

Pin not connected obd Kline adapter

[muki01]

What does this mean. Do you have any problem?

[prai44]

Not connecting to car please send pin to diagram ka line

[prai44]

[muki01]

Did you do the communication scheme I shared?

[prai44]

Yes

[muki01]

Which scheme did you make?

[muki01]

And why you are using pin 32 and pin 33 ? You need to use UART Pins.
