| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-C5 | ESP32-C6 | ESP32-H2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | -------- | -------- | ## ESP-IDF GATT SERVER SPP Example For description of this application please refer to [ESP-IDF GATT CLIENT SPP Example](../ble_spp_client/README.md) ## 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-S3/ESP32-C2/ESP32-H2 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 (4452) GATTS_SPP_DEMO: EVT 14, gatts if 3 I (4452) GATTS_SPP_DEMO: event = e I (5022) GATTS_SPP_DEMO: EVT 4, gatts if 3 I (5022) GATTS_SPP_DEMO: event = 4 I (5152) GATTS_SPP_DEMO: EVT 2, gatts if 3 I (5152) GATTS_SPP_DEMO: event = 2 I (5152) GATTS_SPP_DEMO: ESP_GATTS_WRITE_EVT : handle = 5 I (5242) GATTS_SPP_DEMO: EVT 2, gatts if 3 I (5242) GATTS_SPP_DEMO: event = 2 I (5242) GATTS_SPP_DEMO: ESP_GATTS_WRITE_EVT : handle = 10 I (18462) GATTS_SPP_DEMO: EVT 5, gatts if 3 I (18462) GATTS_SPP_DEMO: event = 5 I (27652) GATTS_SPP_DEMO: EVT 2, gatts if 3 I (27652) GATTS_SPP_DEMO: event = 2 I (27652) GATTS_SPP_DEMO: ESP_GATTS_WRITE_EVT : handle = 2 ``` ## Troubleshooting For any technical queries, please open an [issue](https://github.com/espressif/esp-idf/issues) on GitHub.
