If local control is enabled via config option (CONFIG_ESP_RMAKER_LOCAL_CTRL_AUTO_ENABLE), the enabling/disabling will happen internally and the behaviour will be unchanged. However, if the config option is disabled, applications can still call esp_rmaker_local_ctrl_enable/disable at runtime as and when required, if CONFIG_ESP_RMAKER_LOCAL_CTRL_FEATURE_ENABLE option is enabled. Note that the older config option CONFIG_ESP_RMAKER_LOCAL_CTRL_ENABLE has been renamed to CONFIG_ESP_RMAKER_LOCAL_CTRL_AUTO_ENABLE. However, CONFIG_ESP_RMAKER_LOCAL_CTRL_ENABLE will also continue to work and ensure backward compatibility
Switch Example
Build and Flash firmware
Follow the ESP RainMaker Documentation Get Started section to build and flash this firmware. Just note the path of this example.
What to expect in this example?
- This example uses the BOOT button and RGB LED on the ESP32-S2-Saola-1/ESP32-C3-DevKitC board to demonstrate a switch.
- The LED state (green color) indicates the state of the switch.
- Pressing the BOOT button will toggle the state of the switch and hence the LED. This will also reflect on the phone app.
- Toggling the button on the phone app should toggle the LED on your board, and also print messages like these on the ESP32-S2 monitor:
I (16073) app_main: Received value = true for Switch - power
LED not working?
The ESP32-S2-Saola-1 board has the RGB LED connected to GPIO 18. However, a few earlier boards may have it on GPIO 17. Please use CONFIG_WS2812_LED_GPIO to set the appropriate value.
Reset to Factory
Press and hold the BOOT button for more than 3 seconds to reset the board to factory defaults. You will have to provision the board again to use it.
