Generally you may be right. But using C++ code adds so much to readability and clearness fo code. I want to wrap all BT function into a class where callback will be static member with class pointer passed to it as user parameter as it can be easily done to all other APIs of ESP32. Sadly, many years ...

Hi, Dear IDF authors, this problem exists like since forever. I wan't to write simple app on C++ but GAP/GATTS API doesn't support it. :cry: I'm talking about event handlers. Why esp_event_handler_register has custom arg parameter while neither esp_ble_gap_register_callback nor esp_ble_gatts_registe...

Aparently as suggested by Sudeep (https://github.com/espressif/esp-idf/is ... 1935791232) just need to remove ESP_INTR_FLAG_EDGE flag

You install the ISR before starting the task. This means that the ISR can trigger before TaskBTNReset is initalized.

1. No it cann't untill I press the button - I have pulldown.
2. Same error if I start task before interrupt init.

Hi all, I want to make my ESP32-C3 to restart when I press button connected to GPIO4. Here is my code static TaskHandle_t taskBTNReset; static void IRAM_ATTR reset_button_isr_handler(void* arg) { xTaskNotifyFromISR( taskBTNReset, 0, eNoAction, NULL); } static void task_btn_reset(void* param) { print...

Yes, that's what I thought. Thanks for confirming.
Since I'll be the first who's trying will update here about results

The GPIOs that you mentioned are 5, 18, 21, 22 and 23. Right?

anybody?

Hi all,

I'm want to connect ESP32-PICO-D4 to 1.8V peripheral but I'm a bit confused.

Is it possible to provide 3.3V only for VDDA and VDDA3P3 and 1.8V to VDD3P3_CPU so that GPIO's be 1.8V ?

Hi, Acctording to menuconfig ESP32 supports two ttypes of PSRAM: IS25WP032 and LY68L6400. I didn't find where to by the second one so I decided to use the first one but obviously in 3.3V version (IS25 L P032) since i'm connecting to to 3.3V ESP32 module. Particularly IS25LP032D-JKLE ( PDF ) So far I...

I want to understand how to keep RTC clock working while chip logic is off(if possible)

if I connect VDD3P3_RTC to 3.3V supercapacitor/battery would it be enough? Do I need also to provide 3.3V to CHIP_PU?
