* A return value of type \ref cy_en_ble_api_result_t.
*
* Error Codes | Description
* ------------ | -----------
* CY_BLE_SUCCESS | The Read Request was sent successfully.
* CY_BLE_ERROR_INVALID_PARAMETER | Validation of the input parameter failed.
* CY_BLE_ERROR_GATT_DB_INVALID_ATTR_HANDLE | The peer device doesn't have the particular characteristic.
* CY_BLE_ERROR_INVALID_OPERATION | This operation is not permitted on the specified attribute.
* CY_BLE_ERROR_INVALID_STATE | The state is not valid.
* CY_BLE_ERROR_MEMORY_ALLOCATION_FAILED | Memory allocation failed.
*
* \events
* In case of successful execution (return value = \ref CY_BLE_SUCCESS)
* the following events can appear: \n
* If the PASS service-specific callback is registered
* (with \ref Cy_BLE_PASS_RegisterAttrCallback):
* * #CY_BLE_EVT_PASSC_READ_DESCR_RESPONSE - In case if the requested attribute is
* successfully read on the peer device,
* the details (charIndex, descrIndex, value, etc.)
* are provided with event parameter structure
* of type cy_stc_ble_pass_descr_value_t.
* .
* Otherwise (if the PASS service-specific callback is not registered):
* * #CY_BLE_EVT_GATTC_READ_RSP - In case if the requested attribute is
* successfully read on the peer device,
* the details (handle, value, etc.) are
* provided with event parameters
* structure (cy_stc_ble_gattc_read_rsp_param_t).
* * #CY_BLE_EVT_GATTC_ERROR_RSP - In case if an error occurred with the
* requested attribute on the peer device,
* the details are provided with event parameters
* structure (cy_stc_ble_gatt_err_param_t).
