Provided API releases the user from adding attributes one by one as implemented in BLUEDROID. A demo of the other method to create the attribute table is presented in [gatt_server_demo](../gatt_server). Please, check this [tutorial](tutorial/Gatt_Server_Service_Table_Example_Walkthrough.md) for more information about this example. ## How to Use Example Before project configuration and build, be sure to set the correct chip target using: ```bash idf.py set-target ``` ### Hardware Required * A development board with ESP32/ESP32-C3/ESP32-H4/ESP32-C2/ESP32-S3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.) * A USB cable for Power supply and programming See [Development Boards](https://www.espressif.com/en/products/devkits) for more information about it. ### Build and Flash Run `idf.py -p PORT flash monitor` to build, flash and monitor the project. (To exit the serial monitor, type ``Ctrl-]``.) See the [Getting Started Guide](https://idf.espressif.com/) for full steps to configure and use ESP-IDF to build projects. ## Example Output ``` I (0) cpu_start: Starting scheduler on APP CPU. I (512) BTDM_INIT: BT controller compile version [1342a48] I (522) system_api: Base MAC address is not set I (522) system_api: read default base MAC address from EFUSE I (522) phy_init: phy_version 4670,719f9f6,Feb 18 2021,17:07:07 I (942) GATTS_TABLE_DEMO: create attribute table successfully, the number handle = 8 I (942) GATTS_TABLE_DEMO: SERVICE_START_EVT, status 0, service_handle 40 I (962) GATTS_TABLE_DEMO: advertising start successfully ``` ## Troubleshooting For any technical queries, please open an [issue](https://github.com/espressif/esp-idf/issues) on GitHub.
