- led_light: Use the new bulk write callback (single callback invoked just once for multiple param writes) and use esp_rmaker_param_update() so that all updated params are also reported together. - Other examples: Just replace esp_rmaker_param_update_and_report with esp_rmaker_param_update() and let the Rainmaker core report all updated params together.
GPIO 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 just provides 3 boolean parameters, linked to 3 GPIOS.
- Toggling the buttons on the phone app should toggle the GPIOs on your board (and the LEDs, if any, connected to the GPIOs), and also print messages like these on the ESP32-S2 monitor:
I (16073) app_main: Received value = true for GPIO-Device - Red
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.
