| ## 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 |
| |
| ``` |
| { |
| |
| // Max length is 31 bytes |
| // Enter data in (length, type, value) format |
| // 0x05 - length of data |
| // 0x09 - Type (Complete Local Name) |
| // 0x61, 0x62, 0x63, 0x64 - Data (a,b,c,d) |
| uint8_t scanResponse[] = { 0x05, 0x09, 0x61, 0x62, 0x63, 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`. |
