| ## Nimble: scan response |
| |
| The `ConfigureScanResponseData` API is used to configure the scan response data |
| for advertising in a Bluetooth Low Energy (BLE) application based on the NimBLE |
| BLE stack. Scan response data is additional data that a BLE peripheral device |
| can include in its advertising packets to provide more information about itself. |
| This API allows you to set the scan response data that will be included in the |
| advertising packets. |
| |
| ### Usage |
| |
| ``` |
| { |
| uint8_t scanResponse[31]; // 0x05, 0x09, a, b, c, d |
| scanResponse[0] = 0x05; |
| scanResponse[1] = 0x09; |
| scanResponse[2] = 0x61; |
| scanResponse[3] = 0x62; |
| scanResponse[4] = 0x63; |
| scanResponse[5] = 0x64; |
| chip::ByteSpan data(scanResponse); |
| CHIP_ERROR err = chip::DeviceLayer::Internal::BLEMgrImpl().ConfigureScanResponseData(data); |
| if (err != CHIP_NO_ERROR) |
| { |
| ESP_LOGE(TAG, "Failed to configure scan response, err:%" CHIP_ERROR_FORMAT, err.Format()); |
| } |
| } |
| ``` |
| |
| Note: Scan response should be configure before `InitServer`. |
