Hi
Please help to find bootloader or firmware to download which have turn on WiFi permanently for ESP 32, S3 ( Station mode)
I want to upload LED blinking program to ESP but wifi should remaining turn on
Please advise
You want for the ESP32's WiFi to remain connected when uploading code?
Of Couse yes
How do you expect to upload code with the ESP32 maintaining a WiFi connection when after the code has upload the ESP32 resets so that the newly uploaded code can run?

we just upload the code using USB port
We have esp8266 module which have this capability
we uploaded it stranded LED blinking program as well as it can visible in the wifi search list
Post#5 makes little sense. Could you elaborate?
When trying to upload code to the ESP32 and these ...___...___...___... show up did you press the button to start the upload on the ESP32?
From my understanding, the ESP32 because it has 2 cores and is more sophisticated, has a layered-bootloader architecture: the stage_0 or initial bootloader is ROM-based and thus in silicon which translate to not user accessible:
ESP32 (4) – Flash, bootloader and FreeRTOS – lucadentella.it
In the esp32 ROM memory there’s a small program, named first-stage bootloader . This program is executed at each reset of the chip: it configures the access to the external flash memory and, if required, stores on it new data coming from the serial/USB port (flash process). Once finished, it accesses the flash memory (at address 0x1000) and loads and executes the second-stage bootloader .

Pease give me little time since I am bit away with my ESP sorry[quote="Idahowalker,
Dear I Pressed the boot button during the Connecting .............
Then Following error is displayed
Please note that this ESP32 module does not have auto upload feature hence I need to press Boot button first the Resent button for upload the codes

BlinkRGB
Demonstrates usage of onboard RGB LED on some ESP dev boards.
Calling digitalWrite(RGB_BUILTIN, HIGH) will use hidden RGB driver.
RGBLedWrite demonstrates controll of each channel:
void neopixelWrite(uint8_t pin, uint8_t red_val, uint8_t green_val, uint8_t blue_val)
WARNING: After using digitalWrite to drive RGB LED it will be impossible to drive the same pin

Hoped you requested the code
I'd remove all the connections to the ESP32, and see if it does the thing. From seeing the pins being used in the code, I'd say some pins are being used incorrectly. With all the wires removed does the ESP32 upload the code?

Post a schematic.
