Description

I am developing a project, here uart1 will receive data then uart0 will sent data finally uart0 will receive data, I need to receive data over uart received interrupt. I tested that intially power up the board uart1 can receive and uart0 can sent data for only one time, then hold the board. if i press the reset button, it follow the same only for one time data receiving.

please check my following ISR code:

static void UART_ISR_ROUTINE(void pvParameters)
{
uart_event_t event;
bool exit_condition = false;
while (1) {
if(xQueueReceive(uart1_queue, (void * )&event, (portTickType)portMAX_DELAY)) {
if (event.type == UART_DATA) {
ESP_ERROR_CHECK(uart_get_buffered_data_len(UART_NUM_1, (size_t)&UART1_data_length));
UART1_data_length = uart_read_bytes(UART_NUM_1, UART1_data, UART1_data_length, 100);

         uart_write_bytes(UART_NUM_0, UART1_data, 8);
         ESP_ERROR_CHECK(uart_wait_tx_done(UART_NUM_0, 100));

      }
           else {
            //TODO...
               }     
    }


  if(xQueueReceive(uart0_queue, (void * )&event, (portTickType)portMAX_DELAY)) {
        if (event.type == UART_DATA) {
            ESP_ERROR_CHECK(uart_get_buffered_data_len(UART_NUM_0, (size_t*)&UART0_data_length));
            UART0_data_length = uart_read_bytes(UART_NUM_0, UART0_data, UART0_data_length, 100);

         uart_write_bytes(UART_NUM_0, UART0_data, 8);
         ESP_ERROR_CHECK(uart_wait_tx_done(UART_NUM_0, 100));
         
      }  

          else {
            //TODO...
        } 
    
    }

if (exit_condition) {
break;
}
}

vTaskDelete(NULL);

}

please help me to find out the problem, please suggest me how can i solve this problem. thanks

Debug Message

two uart receive interrupt didnot work

Other Steps to Reproduce

i tested practically, it received the data only one time then got hold

I have checked existing issues, online documentation and the Troubleshooting Guide

Hello @muzahid13,

Serial was refactored and there were a lot of changes since Arduino ESP32 core v1.0.6, which is no longer supported.

Please test your code against v2.0.3-rc1. Thanks.

@muzahid13 - I think the report may be wrong because Arduino Core 1.0.6 has no support for ESP32-S2.

I also see that you are trying to create an UART ISR. It won't work with Arduino.
We have a new HardwareSerial API called onReceive() that runs an user callback function as soon as data arrives to the UART.

Please refer to #6102 (comment) - it is a similar request.

[SuGlider]

Anyway, in order to be able to use onReceive(callBackFunc), it is necessary to use Arduino Core 2.0.3-RC1 (latest one).

@muzahid13 - Can we close this issue?

[SuGlider]

Closing this issue given that it is IDF ISR development related.
This is not Arduino related.
