Hi

I am trying to implement a people counter-based of scans of mobile phones that have the Wi-Fi turned on
Note: I want so say here that I want to know how many people has the Wi-Fi turned on, no the Access point Wi-Fi mode. I don´t want
a trivial Wi-Fi Scan example

I saw in Arduino IDE that ...

Good morning.

I am developing a tracker based on a ESP32.

I need to reset a counter variable every time I receive a '1' logic in GPIO 27.

I started using ext1 wake up (because I have different wake-up sources)

However, my problem is that I don´t want to wake up the ESP32 every time I get a '1 ...

Good morning.

My name is Jorge and I am a Firmware developer for Sayme Corp.

I am programming an IoT Device based on an ESP32 WROOM 32D. The functions of the ESP32 are:
1) Use it as a microcontroller
2) Scan Wi-Fi networks.
3) Scan BLEs

I am developing the application with PlatformIO.
A month ago ...

I just try to use:

//GPIO_SEL_5 (Regulator TPS610986DSER, PWR_MODE)
gpio_struct.pin_bit_mask = GPIO_SEL_5;
gpio_struct.mode = GPIO_MODE_OUTPUT;
gpio_struct.pull_up_en = GPIO_PULLUP_DISABLE;
gpio_struct.pull_down_en = GPIO_PULLDOWN_ENABLE;
gpio_struct.intr_type = GPIO_INTR_DISABLE;
ESP ...

I am developing an application with an ESP32 as a microcontroller.
I always use the same function to have the minimum power consumption (above 8 - 10 uA) and I have never had problems.

But in this development, I use GPIO_NUM_5 to turn on/off a 3,3 Volts regulator. With a '0' the regulator is off ...

There is an example in the examples folder for doing just that.

Can you give me the link to this example?

Thanks in advance

Good morning.

I am developing an ESP32 code where I use UART communications.

I want to know how can I wait until I have a delimiter on RX data or I wait X time, at the same time,

int uart_read_bytes(uart_port_t uart_num, char* buf, uint32_t length, TickType_t ticks_to_wait) always wait the number ...

Good Afternoon,
I am doing an application for ESP32 (32D).

In order to avoid high power compsuptions I am using 2 functions with RTC I/O's.
For example, with GPIO 0:
rtc_gpio_init(GPIO_NUM_0);
rtc_gpio_isolate(GPIO_NUM_0);

As I told before, I am using this 2 functions with all RTC I/O's.

The ...
