Function bt_br_set_class_of_device 

pub unsafe extern "C" fn bt_br_set_class_of_device(cod: u32) -> i32

@brief Set the Class of Device of the local BR/EDR Controller.

This function writes the Class of Device (COD) value to the BR/EDR controller. The COD is used by remote devices during the discovery process to identify the type of device and the services it provides.

@note The limited discoverable mode bit (@ref BT_COD_MAJOR_SVC_CLASS_LIMITED_DISCOVER) cannot be set directly through this function. Use bt_br_set_discoverable() with the limited parameter to enable limited discoverable mode, which will automatically set the corresponding COD bit.

@param cod Class of Device value to set. This should be a combination of Major Service Class bits (BT_COD_MAJOR_SVC_CLASS_), Major Device Class bits (BT_COD_MAJOR_DEVICE_CLASS_), and Minor Device Class bits (BT_COD_MINOR_DEVICE_CLASS_*).

@retval 0 on success @retval -EAGAIN if the Bluetooth device is not ready @retval -EINVAL if the provided COD value attempts to set the limited discoverable bit directly, which is not permitted @retval Other negative error codes from underlying HCI command failures
