How to send logging via cli over UART

Question

Dear support team, I would like to simultaneously use logging and CLI via UART in an application running on the NRF52810 with Softdevice S112. In my application, I need to use UART (and not on RTT). In my " main.c ", I am calling 
 
 Log_Init() : Mainly calling NRF_LOG_INIT(NULL) I don't call the macro " NRF_LOG_DEFAULT_BACKENDS_INIT() " (according to Link ) 
 CLI_Init() : Calling nrf_cli_init(...) 
 CLI_Start() : Calling nrf_cli_start(&m_cli_uart); 
 
 CLI and CLI via UART are defined by these macros: 
 NRF_CLI_UART_DEF(m_cli_uart_transport, 0, 64, 16); NRF_CLI_DEF(m_cli_uart, "my-app:~$ ", &m_cli_uart_transport.transport, '\r', CLI_APP_LOG_QUEUE_SIZE); 
 Logging is always done with the NRF_LOG_INFO() macro. At current, I only receive those logs 
 
 which are invoked in " main " and 
 which are followed by a NRF_LOG_FLUSH() . ("Followed" means that at least one NRF_LOG_FLUSH() is needed before entering the infinite task loop to see the log output.) 
 
 I would also like to do some logging in subroutines, but NRF_LOG_FLUSH() can only be called in "main" or in an assert handler (see https://devzone.nordicsemi.com/f/nordic-q-a/50683/nrf_log_flush-issue ). 
 What am I doing wrong? Here are my potentially relevant CLI and LOG settings in sdk_config.h:
