| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-C6 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | -------- | # Bytebeam Toggle LED Example This example demonnstrates how to control the led gpio from Bytebeam IoT Platform. ## Hardware Required - A development board with Espressif SoC (e.g.,ESP32-DevKitC, ESP-WROVER-KIT, etc.) - A USB cable for Power supply and programming ## Software Required - ESP-IDF - Bytebeam ESP-IDF SDK ## Project Configurations Open the project configuration menu (`idf.py menuconfig`). In the `Example Configuration` menu: - Set the Wi-Fi configuration. - Set `WiFi SSID`. - Set `WiFi Password`. Optional: If you need, change the other options according to your requirements. ## 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://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects. ## Example Output ``` I (5697) BYTEBEAM_TOGGLE_LED_EXAMPLE: Initializing SNTP I (5707) BYTEBEAM_TOGGLE_LED_EXAMPLE: Waiting for system time to be set...
