I added but get same results. Additionally, an error occurs E (32137) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:

Hi,
thank You for reply.

Any help?

Hello, I am connected to communication line. Device is sending two frames of bytes with gap between. I use code: #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "esp_system.h" #include "esp_log.h" #include "driver/uart.h" #include "string.h" #include "driver/gpio.h" static const i...

I found the solution here:

I had to make struck like above
Result: Thank You very much.

Probably I found the solution.
Now testing.

Oh, ESP_Sprite thank You as well.

PeterR, thank You for reply. Asking for 1 byte: uint8_t data[1]; while (1) { int len = uart_read_bytes(UART_NUM_2, data, 1, 1); uart_write_bytes(UART_NUM_2, (const char *)data, len); } Result: screen8.png Added FIFO Tresh uart_intr_config_t uart_intr = { .rxfifo_full_thresh = 1}; // // .rx_timeout_t...

Thank you very much PeterR for your answer.
The upper signal is RX the lower TX as You assumed.
I can't change the baudrate, data is read from the connected device and sent alternately.
Could you please explain how to reduce latency?
