I want to make an interrupt while deep sleep

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' on GP...

Bluetooth Module overflows maximun Flash size

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, E...

Re: GPIO_NUM_5 has weird state before deep sleep

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_ERROR_CHECK(gp...

GPIO_NUM_5 has weird state before deep sleep

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 and...

There is an example in the examples folder for doing just that.
Can you give me the link to this example?

Thanks in advance

How to wait UART untill timeout or data readed delimiter

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 of...

ESP32 locks UART1

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 power c...
