◆ Cy_BLE_AIOSC_SetCharacteristicValueWithoutResponse()
This function is used to write the characteristic (which is identified by charIndex) value attribute in the server without response.
- Parameters
-
connHandle | The connection handle. |
charIndex | The index of the service characteristic. |
charInstance | The instance number of the characteristic specified by "charIndex". |
attrSize | The size of the characteristic value attribute. |
attrValue | The pointer to the characteristic value data that should be sent to the server device. |
- Returns
- A return value of type cy_en_ble_api_result_t.
Error Codes | Description |
CY_BLE_SUCCESS | The request was sent successfully. |
CY_BLE_ERROR_INVALID_PARAMETER | Validation of the input parameter failed. |
CY_BLE_ERROR_INVALID_OPERATION | Operation is invalid for this descriptor. |
CY_BLE_ERROR_GATT_DB_INVALID_ATTR_HANDLE | The peer device doesn't have the particular characteristic. |
CY_BLE_ERROR_INVALID_STATE | Connection with the server is not established. |
CY_BLE_ERROR_MEMORY_ALLOCATION_FAILED | Memory allocation failed. |
◆ Cy_BLE_AIOSC_SetCharacteristicValue()
This function is used to write the characteristic (which is identified by charIndex) value attribute in the server.
As a result, a Write Request is sent to the GATT Server and on successful execution of the request on the server side, the CY_BLE_EVT_AIOSS_WRITE_CHAR event is generated. On successful request execution on the server side, the Write Response is sent to the client.
- Parameters
-
connHandle | The connection handle. |
charIndex | The index of the service characteristic. Starts with zero. |
charInstance | The instance number of the characteristic specified by "charIndex". |
attrSize | The size of the characteristic value attribute. |
attrValue | The pointer to the characteristic value data that should be sent to the server device. |
- Returns
- A return value of type cy_en_ble_api_result_t.
Error Codes | Description |
CY_BLE_SUCCESS | The request was sent successfully. |
CY_BLE_ERROR_INVALID_PARAMETER | Validation of the input parameter failed. |
CY_BLE_ERROR_INVALID_OPERATION | Operation is invalid for this characteristic. |
CY_BLE_ERROR_GATT_DB_INVALID_ATTR_HANDLE | The peer device doesn't have the particular characteristic. |
CY_BLE_ERROR_INVALID_STATE | Connection with the server is not established. |
CY_BLE_ERROR_MEMORY_ALLOCATION_FAILED | Memory allocation failed. |
- Events
- In case of successful execution (return value = CY_BLE_SUCCESS) the following events can appear:
If the AIOS service-specific callback is registered with Cy_BLE_AIOS_RegisterAttrCallback():
Otherwise (if an AIOS service-specific callback is not registered):
◆ Cy_BLE_AIOSC_GetCharacteristicValue()
This function is used to read a characteristic value, which is a value identified by charIndex, from the server.
- Parameters
-
connHandle | The connection handle. |
charIndex | The index of the service characteristic. Starts with zero. |
charInstance | The instance number of the characteristic specified by "charIndex". |
- Returns
- A return value of type cy_en_ble_api_result_t.
Error Codes | Description |
CY_BLE_SUCCESS | The request was sent successfully. |
CY_BLE_ERROR_INVALID_PARAMETER | Validation of the input parameter failed. |
CY_BLE_ERROR_INVALID_OPERATION | Operation is invalid for this characteristic. |
CY_BLE_ERROR_GATT_DB_INVALID_ATTR_HANDLE | The peer device doesn't have the particular characteristic. |
CY_BLE_ERROR_INVALID_STATE | Connection with the server is not established. |
CY_BLE_ERROR_MEMORY_ALLOCATION_FAILED | Memory allocation failed. |
- Events
- In case of successful execution (return value = CY_BLE_SUCCESS) the following events can appear:
If the AIOS service-specific callback is registered with Cy_BLE_AIOS_RegisterAttrCallback():
Otherwise (if an AIOS service-specific callback is not registered):
◆ Cy_BLE_AIOSC_SetCharacteristicDescriptor()
This function is used to write the characteristic (which is identified by charIndex) value attribute in the server.
As a result a Write Request is sent to the GATT server and on successful execution of the request on the server side, the CY_BLE_EVT_AIOSS_DESCR_WRITE event is generated. On successful request execution on the server side, the Write Response is sent to the client.
Internally, a Write Request is sent to the GATT server and on successful execution of the request on the server side, the following events can be generated:
- Parameters
-
connHandle | The connection handle. |
charIndex | The index of the service characteristic. Starts with zero. |
descrIndex | The index of the service characteristic descriptor. |
charInstance | The instance number of the characteristic specified by "charIndex". |
attrSize | The size of the characteristic value attribute. |
attrValue | The pointer to the characteristic descriptor value data that should be sent to the server device. |
- Returns
- A return value of type cy_en_ble_api_result_t.
Error Codes | Description |
CY_BLE_SUCCESS | The request was sent successfully. |
CY_BLE_ERROR_INVALID_PARAMETER | Validation of the input parameter failed. |
CY_BLE_ERROR_INVALID_OPERATION | Operation is invalid for this descriptor. |
CY_BLE_ERROR_GATT_DB_INVALID_ATTR_HANDLE | The peer device doesn't have the particular descriptor. |
CY_BLE_ERROR_INVALID_STATE | Connection with the server is not established. |
CY_BLE_ERROR_MEMORY_ALLOCATION_FAILED | Memory allocation failed. |
- Events
- In case of successful execution (return value = CY_BLE_SUCCESS) the following events can appear:
If the AIOS service-specific callback is registered with Cy_BLE_AIOS_RegisterAttrCallback():
Otherwise (if an AIOS service-specific callback is not registered):
