)

Retrieve the attribute UUID and/or metadata.

Parameters

[out]p_mdMetadata of the attribute. Use NULL to omit this field.
Return values
NRF_SUCCESSSuccessfully retrieved the attribute metadata,

ble_gatts_char_md_t const *  p_char_md,
ble_gatts_attr_t const *  p_attr_char_value,
ble_gatts_char_handles_t p_handles 
)

Add a characteristic declaration, a characteristic value declaration and optional characteristic descriptor declarations to the Attribute Table.

Note
It is currently only possible to add a characteristic to the last added service (i.e. only sequential population is supported at this time).
Several restrictions apply to the parameters, such as matching permissions between the user description descriptor and the writable auxiliaries bits, readable (no security) and writable (selectable) CCCDs and SCCDs and valid presentation format values.
If no metadata is provided for the optional descriptors, their permissions will be derived from the characteristic permissions.

uint32_t sd_ble_gatts_exchange_mtu_reply ( uint16_t  conn_handle,
uint16_t  server_rx_mtu 
)

Reply to an ATT_MTU exchange request by sending an Exchange MTU Response to the client.

This function is only used to reply to a BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST event.

The SoftDevice sets ATT_MTU to the minimum of:

However, the SoftDevice never sets ATT_MTU lower than BLE_GATT_ATT_MTU_DEFAULT.

Relevant Message Sequence Charts
GATTS ATT_MTU Exchange
Parameters
[in]conn_handleThe connection handle identifying the connection to perform this procedure on.
[in]server_rx_mtuServer RX MTU size.
Return values
NRF_SUCCESSSuccessfully sent response to the client.
BLE_ERROR_INVALID_CONN_HANDLEInvalid Connection Handle.
NRF_ERROR_INVALID_STATEInvalid Connection State or no ATT_MTU exchange request pending.
NRF_ERROR_INVALID_PARAMInvalid Server RX MTU size supplied.
NRF_ERROR_TIMEOUTThere has been a GATT procedure timeout. No new GATT procedure can be performed without reestablishing the connection.
uint32_t sd_ble_gatts_hvx ( uint16_t  conn_handle,
ble_gatts_hvx_params_t const *  p_hvx_params 
)

Notify or Indicate an attribute value.

This function checks for the relevant Client Characteristic Configuration descriptor value to verify that the relevant operation (notification or indication) has been enabled by the client. It is also able to update the attribute value before issuing the PDU, so that the application can atomically perform a value update and a server initiated transaction with a single API call.

Note
The local attribute value may be updated even if an outgoing packet is not sent to the peer due to an error during execution. The Attribute Table has been updated if one of the following error codes is returned: NRF_ERROR_INVALID_STATE, NRF_ERROR_BUSY, NRF_ERROR_FORBIDDEN, BLE_ERROR_GATTS_SYS_ATTR_MISSING and NRF_ERROR_RESOURCES. The caller can check whether the value has been updated by looking at the contents of *(ble_gatts_hvx_params_t::p_len).
Only one indication procedure can be ongoing per connection at a time. If the application tries to indicate an attribute value while another indication procedure is ongoing, the function call will return NRF_ERROR_BUSY. A BLE_GATTS_EVT_HVC event will be issued as soon as the confirmation arrives from the peer.
The number of Handle Value Notifications that can be queued is configured by ble_gatts_conn_cfg_t::hvn_tx_queue_size When the queue is full, the function call will return NRF_ERROR_RESOURCES. A BLE_GATTS_EVT_HVN_TX_COMPLETE event will be issued as soon as the transmission of the notification is complete.
The application can keep track of the available queue element count for notifications by following the procedure below:
  • Store initial queue element count in a variable.
  • Decrement the variable, which stores the currently available queue element count, by one when a call to this function returns NRF_SUCCESS.
  • Increment the variable, which stores the current available queue element count, by the count variable in BLE_GATTS_EVT_HVN_TX_COMPLETE event.
Events generated
BLE_GATTS_EVT_HVN_TX_COMPLETENotification transmission complete.
BLE_GATTS_EVT_HVCConfirmation received from the peer.

If ble_gatts_hvx_params_t::p_data contains a non-NULL pointer the attribute value will be updated with the contents pointed by it before sending the notification or indication. If the attribute value is updated, ble_gatts_hvx_params_t::p_len is updated by the SoftDevice to contain the number of actual bytes written, else it will be set to 0.

uint8_t *  p_sys_attr_data,
uint16_t *  p_len,
uint32_t  flags 
)

Retrieve persistent system attribute information from the stack.

This call is used to retrieve information about values to be stored persistently by the application during the lifetime of a connection or after it has been terminated. When a new connection is established with the same bonded device, the system attribute information retrieved with this function should be restored using using sd_ble_gatts_sys_attr_set. If retrieved after disconnection, the data should be read before a new connection established. The connection handle for the previous, now disconnected, connection will remain valid until a new one is created to allow this API call to refer to it. Connection handles belonging to active connections can be used as well, but care should be taken since the system attributes may be written to at any time by the peer during a connection's lifetime.

Note
When the BLE_GATTS_SYS_ATTR_FLAG_SYS_SRVCS is used with this function, only the system attributes included in system services will be returned.
When the BLE_GATTS_SYS_ATTR_FLAG_USR_SRVCS is used with this function, only the system attributes included in user services will be returned.
Relevant Message Sequence Charts
GATTS System Attributes Handling: Bonded Peer
Parameters
[in]conn_handleConnection handle of the recently terminated connection.
[out]p_sys_attr_dataPointer to a buffer where updated information about system attributes will be filled in. The format of the data is described in User memory layout for System Attributes. NULL can be provided to obtain the length of the data.
[in,out]p_lenSize of application buffer if p_sys_attr_data is not NULL. Unconditionally updated to actual length of system attribute data.
[in]flagsOptional additional flags, see System Attribute Flags
Return values
NRF_SUCCESSSuccessfully retrieved the system attribute information.
BLE_ERROR_INVALID_CONN_HANDLEInvalid Connection Handle.
NRF_ERROR_INVALID_ADDRInvalid pointer supplied.
NRF_ERROR_INVALID_PARAMInvalid flags supplied.
NRF_ERROR_DATA_SIZEThe system attribute information did not fit into the provided buffer.
NRF_ERROR_NOT_FOUNDNo system attributes found.
uint32_t sd_ble_gatts_sys_attr_set ( uint16_t  conn_handle,
uint8_t const *  p_sys_attr_data,
uint16_t  len,
uint32_t  flags 
)

Update persistent system attribute information.

Supply information about persistent system attributes to the stack, previously obtained using sd_ble_gatts_sys_attr_get. This call is only allowed for active connections, and is usually made immediately after a connection is established with an known bonded device, often as a response to a BLE_GATTS_EVT_SYS_ATTR_MISSING.

p_sysattrs may point directly to the application's stored copy of the system attributes obtained using sd_ble_gatts_sys_attr_get. If the pointer is NULL, the system attribute info is initialized, assuming that the application does not have any previously saved system attribute data for this device.

Note
The state of persistent system attributes is reset upon connection establishment and then remembered for its duration.
If this call returns with an error code different from NRF_SUCCESS, the storage of persistent system attributes may have been completed only partially. This means that the state of the attribute table is undefined, and the application should either provide a new set of attributes using this same call or reset the SoftDevice to return to a known state.
When the BLE_GATTS_SYS_ATTR_FLAG_SYS_SRVCS is used with this function, only the system attributes included in system services will be modified.
When the BLE_GATTS_SYS_ATTR_FLAG_USR_SRVCS is used with this function, only the system attributes included in user services will be modified.

uint16_t  handle,

)

Get the value of a given attribute.

Note
If the attribute value is longer than the size of the supplied buffer, ble_gatts_value_t::len will return the total attribute value length (excluding offset), and not the number of bytes actually returned in ble_gatts_value_t::p_value. The application may use this information to allocate a suitable buffer size.
When retrieving system attribute values with this function, the connection handle may refer to an already disconnected connection. Refer to the documentation of sd_ble_gatts_sys_attr_get for further information.
