UART LOG BACKEND constantly sends datas

[Sylvain]

Hi everyone,

I have configured the LOG module to use it with the UART in view of debugging.

I don't send anything in my loop but the UART send constantly these data :

<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 length: 38.
<info> uart: TX req id:2 leng.........

here's my main :

int main(void)
{
    APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
    NRF_LOG_DEFAULT_BACKENDS_INIT();

    NRF_LOG_INFO("\r\nUART debugging is working");

    /*Macro for processing all log entries from the buffer.
    It blocks until all buffered entries are processed by the backend.*/
    NRF_LOG_FLUSH();
        
    timer_init();
    gpio_init();

    while (true)
    {
        // Do nothing.
    }
}

Sincerely,

Sylvain.

The behavior come from this define :

// <e> UART_CONFIG_LOG_ENABLED - Enables logging in the module.
//==========================================================
#ifndef UART_CONFIG_LOG_ENABLED
#define UART_CONFIG_LOG_ENABLED 1
#endif


The UART CONFIG LOG need to be disable to remove the configuration info of the UART ...
