Piyush Shah cd173972a7 examples: Enable CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE in all examples
.. Since this is the recommended setting and well supported by the
RainMaker SDK, to ensure that OTA upgrades do not break the device
and ensure that the MQTT connection works fine with the new firmware.

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.
