Disable SHELL logger backend at runtime

I managed to get it working.

I used log_backend_disable() api for both SHELL and UART to completely disable logs then used log_backend_enable() to re-enable logging.

// to disable
    log_backend_disable(log_backend_get_by_name("shell_uart_backend"));
    log_backend_disable(log_backend_get_by_name("log_backend_uart"));
    
// to enable

log_backend_enable(
        log_backend_get_by_name("log_backend_uart"),
        NULL,
        LOG_LEVEL_INF);

log_backend_enable(
        log_backend_get_by_name("shell_uart_backend"),
        (void*) shell_backend_uart_get_ptr(),
        LOG_LEVEL_INF);

[quote user="Ahmed Samir"]Is there a similar API in ncs/v2.4.1?[/quote]

Yes, I can find this function in Search — nRF Connect SDK 2.4.3 documentation (nordicsemi.com).

It should be since you need to specify backend argument uint32_t log_filter_set(struct log_backend const *const backend, uint32_t domain_id, int16_t source_id, uint32_t level).

Hi Ahmed,

Yes, I think you can try runtime log filter to disabled log output on target backend with LOG_LEVEL_NONE.

You can search log_filter_set in ncs/v2.6.0 to learn its usage.
