I've been using esp32-wroom-32D modules in various projects for quite a while, but only recently started a project where the esp32 is battery powered and low power consumption is of the greatest importance. And I am very disappointed. Even in deep sleep mode, there are cyclical increases of current ...

ok, I found a problem: Serial.printf was the culprit.

Hi All, I always get ESP32-WROOM-32D module reset when calling scanNetworks function asynchronously (with parameter: true). Below is a code snippet. (Entire sketch taken from: https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/scan-examples.html, please refer to the last example on this pa...

I'm creating a timer in a setup() function: hw_timer_t * timer_grab = NULL; void setup() { timer_grab = timerBegin(1, 80, true); timerAttachInterrupt(timer_grab, &onTimer_grab, true); timerAlarmWrite(timer_grab, 3000000, false); //running it once (parameter false) timerAlarmEnable(timer_grab); } and...

Hi, why the task function
static void example_espnow_task(void *pvParameter) {....}
in the espnow_example_main.c doesn't have an infinite loop inside?
As I understand, according to FreeRTOS documentation, all task functions must be implemented with the infinite loop and never return.

Hi All, I'm wondering why the RTC_GPIO_IN_NEXT definition in rtc_io_reg.h is: #define RTC_GPIO_IN_NEXT 0x0003FFFF According to the specs, the GPIO17 - GPIO0 match bit31-bit14 in RTC_GPIO_IN_REG. All lower bits (13-0) are reserved. Therefore shouldn't it be: #define RTC_GPIO_IN_NEXT 0x00003FFF ? Rega...
