Where is the boot button? A lot of times the IO 0 is used to but the ESP32-S3 into boot mode then Windows will recognize the USB port as a COM port. Here can find an example: https://learn.adafruit.com/assets/112329

Yes go into menuconfig: idf.py menuconfig Component config ---> Bluetooth ----> Host (NimBLE - BLE only) ---> (X) NimBLE - BLE only NimBLE Options ---> change (3) Maximum number of concurrent connections (NEW) 3 into 1 (Top) → Component config → Bluetooth → NimBLE Options Espressif IoT Development F...

I get an error when I compile for the ESP32-C6 chip the same code works for the ESP32-S3. Is it a known problem? here is the error: C:/Espressif/frameworks/esp-idf-v5.2.1/examples/Brainwave/ESP32C6_Test_LED_BLE_nimble/main/main.c:8:10: fatal error: esp_nimble_hci.h: No such file or directory 8 | #in...
