GATT Robust Caching API.

Functions

void wiced_bt_gatt_set_client_supported_features(uint16_t conn_id, wiced_bt_gatt_client_supported_features_t csfs)¶

Set the remote client supported features upon write and for bonded device after reconnect as read from NVRAM.

Parameters

Returns

None

void wiced_bt_gatt_get_client_supported_features(uint16_t conn_id, wiced_bt_gatt_client_supported_features_t csfs)¶

Get the remote client supported features.

Parameters

conn_id – [in] : GATT Connection ID
csfs – [in] : Bit mask set in wiced_bt_gatt_set_client_supported_features

Returns

None

void wiced_bt_gatt_get_peer_caching_status(uint16_t conn_id, wiced_bt_gatt_caching_status_t *caching_status)¶

Function wiced_bt_gatt_get_peer_caching_status Can be used by the server application to read the robust caching status of the peer.

Parameters

conn_id – [in] connection identifier.
caching_status – [out] GATT_PEER_CLIENT_CACHE_CHANGE_AWARE/GATT_PEER_CLIENT_CACHE_CHANGE_UNAWARE

Returns

None

void wiced_bt_gatt_set_peer_caching_status(uint16_t conn_id, wiced_bt_gatt_caching_status_t status)¶

This function is used by the application to set peer’s caching state.

The application is expected to store the last wiced_bt_db_hash_t shared with the bonded peer in NVRAM On connection, the application compares the stored wiced_bt_db_hash_t with the current db_hash. If the hashes match, the status is set to GATT_PEER_CLIENT_CACHE_CHANGE_AWARE else GATT_PEER_CLIENT_CACHE_CHANGE_UNAWARE

Parameters

Returns

None
