ESP32S3 randomly stopped working

Hi there, Can I make a suggestion, Have you tried using 2.0.8 BSP?
GL :slight_smile: PJ
can you provide the compiler output from the build first 20 lines and last 20 lines would be sufficient

Hi PJ,

Nope, I even didn’t know such a thing exists. Looks like Seeed Studio’s ESP32S3 is not supported according to this.


Hi there,
No It is , They use the Variant listed int the Table from the link in that Github wiki, Bottom of page.
However Seeed Studio Should make a concerted effort to get them recognised in Arduino , PlatfronIO and IDF and the nordic SDK. IMO

In arduino IDE you can select a version prior to the Alpha, I tried using 2.0.8 and the attached code, I don’t have the WebSocketCleint.h version?

Have you tried it on an Xiao ESP32C3 ?

Add this code before while loop in setup function to print out near wifi check if it discovered wifi or not

  // WiFi.scanNetworks will return the number of networks found
  int n = WiFi.scanNetworks();
  Serial.println("scan done");
  if (n == 0) {
      Serial.println("no networks found");
  else {
    Serial.println(" networks found");
    for (int i = 0; i < n; ++i) {
      // Print SSID and RSSI for each network found
      Serial.print(i + 1);
      Serial.print(": ");
      Serial.print(" (");
      Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN)?" ":"*");

Xiao esp32 s3 come with antenna. You have antenna on it or not?

Hello faizannazir,

Thanks for your answer. I was late to answer sorry for that.
Yes, I use the antenna of course.
I uploaded the code you gave me and it did not work as well.
I keeps disconnecting.
I think it is because the driver of the microcontroller is corrupted. How can I upload a new driver for XIAO ESP32S3?

Thanks a lot.

maybe wifimulti library causing issue

Hi there,
If you mean to reload the Factory bin file it’s here on the WiKi
ESP_RF_Test tool is used to flash it to the chip.
If memory serves me the tool ALSO has a Factory Flash file present.

you guys crack me up…

Hi PJ,

Imma give it a try thanks a lot.

Have a great day.

Hi waltney,

Yes, I do not know how these work properly so I am struggling :smiley:

Have a nice day.
