Connecting ESP32-S3-OTG to HID device

[vapisoft]

Hi,

I purchased ESP32-S3-WROOM from Freenove in order to ccreate a BLE bridge from my HID sensor to a PC.
I programmed the device to send data continuesly so I can see that the ESP can read the data from the sensor.
I used several HID exampes but in none of them I can see any data.

The example I use now is: ble_hidd_demo from:
https://github.com/espressif/esp-idf/bl ... /README.md

I expect to see something in my event callback.
static void hidd_event_callback(esp_hidd_cb_event_t event, esp_hidd_cb_param_t *param)

This is the "Terminal outout that I receive"
