 In the main task, interrupts are enabled and disabled only on the GPIO pin used and [on the core](https://github.com/TIT8/shelly_esp32_button_espidf/blob/1ccbeb450f857612228f9be3fbcbf5ec52a6ecf3/src/main.c#L190) where the task is pinned, akin to a critical section, as outlined in the [official documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/freertos_idf.html#disabling-interrupts).

-The code handles the scenario where the button is continuously pressed; after a while, the main thread will enter a blocked state. You can refer to [the relevant part of the firmware](https://github.com/TIT8/shelly_esp32_button_espidf/blob/88ec38896c9c9199dd878153d043701d34ed38f2/src/main.c#L265) for more details.

Meanwhile, with busy waiting, the time consumed by the main task could be critical for other tasks to execute.**
 
 Obviously, putting the ESP32 to sleep until it's awakened by the GPIO would be much more efficient. However, the latency from button press to waking the CPU, connecting to WiFi and MQTT, and sending commands will decrease the responsiveness of the application (on the ESP32, you cannot put the CPU into deep sleep without turning off the radio).
