• This API can only be used if the service is maintained inside the firmware. The services which are maintained by firmware must follow the below rules. Rule 1: The attribute_data_size is less than 20 bytes during the service_creation Rule 2: while creating the service, don't use the RSI_BLE_ATT_MAINTAIN_IN_HOST bit in the RSI_BLE_ATT_CONFIG_BITMAP macro. Rule 3: The data_len must be less than or equal to the dat_length mentioned while creating the service/attribute Rule 4: If the services are maintained in the Application/Host, then need to use rsi_ble_notify_value() API to send the notifications to the remote devices.

Note

• Refer Error Codes section for above error codes Error Codes

• If the services are maintained in the Application/Host, then need to use rsi_ble_notify_value() API instead of using rsi_ble_set_local_att_value() API to send the notifications to the remote devices.
