1| Supported Targets | ESP32-C3 | ESP32-S3 | 2| ----------------- | -------- | -------- | 3 4# ESP-IDF Periodic Sync Example 5 6This example supports the periodic extended scan to scan the extended advertisement. 7 8To test this demo, we can run the [periodic_adv_demo](../peroidic_adv), which can start extended advertisement with supported param. 9 10Please, check this [tutorial](tutorial/Periodic_Sync_Example_Walkthrough.md) for more information about this example. 11 12## How to Use Example 13 14Before project configuration and build, be sure to set the correct chip target using: 15 16```bash 17idf.py set-target <chip_name> 18``` 19 20### Hardware Required 21 22* A development board with ESP32-C3 SoC, ESP32-S3 and BLE5.0 supported chips (e.g., ESP32-C3-DevKitC-1, etc.) 23* A USB cable for Power supply and programming 24 25See [Development Boards](https://www.espressif.com/en/products/devkits) for more information about it. 26 27### Build and Flash 28 29Run `idf.py -p PORT flash monitor` to build, flash and monitor the project. 30 31(To exit the serial monitor, type ``Ctrl-]``.) 32 33See the [Getting Started Guide](https://idf.espressif.com/) for full steps to configure and use ESP-IDF to build projects. 34 35## Example Output 36 37``` 38 39I (362) BTDM_INIT: BT controller compile version [3e61eea] 40I (372) coexist: coexist rom version 8459080 41I (372) phy_init: phy_version 500,985899c,Apr 19 2021,16:05:08 42I (492) system_api: Base MAC address is not set 43I (492) system_api: read default base MAC address from EFUSE 44I (492) BTDM_INIT: Bluetooth MAC: 7c:df:a1:40:01:c5 45 46Output1 Without advertisement: 47 48I (712) PERIODIC_SYNC: ESP_GAP_BLE_SET_EXT_SCAN_PARAMS_COMPLETE_EVT, status 0 49I (712) PERIODIC_SYNC: ESP_GAP_BLE_EXT_SCAN_START_COMPLETE_EVT, status 0 50 51Output2 with advetisement: 52 53I (712) PERIODIC_SYNC: ESP_GAP_BLE_SET_EXT_SCAN_PARAMS_COMPLETE_EVT, status 0 54I (712) PERIODIC_SYNC: ESP_GAP_BLE_EXT_SCAN_START_COMPLETE_EVT, status 0 55I (712) PERIODIC_SYNC: Start create sync with the peer device ESP_MULTI_ADV_80MS 56I (722) PERIODIC_SYNC: ESP_GAP_BLE_PERIODIC_ADV_CREATE_SYNC_COMPLETE_EVT, status 0 57I (812) PERIODIC_SYNC: ESP_GAP_BLE_PERIODIC_ADV_SYNC_ESTAB_EVT, status 0 58I (812) sync addr: c0 de 52 00 00 02 59I (812) PERIODIC_SYNC: sync handle 1 sid 0 perioic adv interval 64 adv phy 2 60I (812) PERIODIC_SYNC: periodic adv report, sync handle 1 data status 0 data len 28 rssi -48 61I (892) PERIODIC_SYNC: periodic adv report, sync handle 1 data status 0 data len 28 rssi -47 62I (972) PERIODIC_SYNC: periodic adv report, sync handle 1 data status 0 data len 28 rssi -48 63I (1052) PERIODIC_SYNC: periodic adv report, sync handle 1 data status 0 data len 28 rssi -47 64I (1132) PERIODIC_SYNC: periodic adv report, sync handle 1 data status 0 data len 28 rssi -49 65I (1212) PERIODIC_SYNC: periodic adv report, sync handle 1 data status 0 data len 28 rssi -48 66I (1292) PERIODIC_SYNC: ESP_GAP_BLE_PERIODIC_ADV_SYNC_LOST_EVT, sync handle 1 67 68``` 69 70## Troubleshooting 71 72For any technical queries, please open an [issue](https://github.com/espressif/esp-idf/issues) on GitHub.
