A fatal error occurred: This chip is ESP32-C3 not ESP32. Wrong --chip argument?

does not work for c3

Does the keyboard library work for you? https://github.com/T-vK/ESP32-BLE-Keyboard/issues/133

[leCandas]

I can try it will let you know I am using M5STAMP C3 btw

esp32-c3 could pair success to my phone, but it could not link in my phone.

I just use the sample

#include <BleKeyboard.h>

BleKeyboard bleKeyboard;

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");
  bleKeyboard.begin();
}

void loop() {
  if(bleKeyboard.isConnected()) {
    Serial.println("wait 10s");
    delay(10000);

    Serial.println("Sending 'Hello world'...");
    bleKeyboard.print("Hello world");

    delay(1000);

    Serial.println("Sending Enter key...");
    bleKeyboard.write(KEY_RETURN);

    delay(1000);
    
    delay(100);
    bleKeyboard.releaseAll();

  }
  Serial.println("Waiting 5 seconds...");
  delay(5000);
}

That's its log

I can not understand.

I solve this problem just now.I find I did not change the chip type to ESP32C3.Because I new a project,the default chip type is ESP32 .
