Lost LOGs - increase LOG backend queue size.

Question

Hello, how can I increase LOG backend queue size? I was comparing some sdk_config settings with some examples, but did not find difference and the example does not fire this message. I am not logging much more info than the example. 
 Thank you.

I have fixed it. Unfortunately don't know how and why. I just took the sdk_config.h file from the flash_fstorage example and compiled my project. Now everything seems to work fine. 
 I tried to compare my sdk_config with the one in the flash_fstorage but I failed. This is something what should be improved somehow - the documentation of sdk_config.

Ok, I have found the reason, it is this line: 
 #define NRF_LOG_DEFERRED 0 It has to be changed for: 
 #define NRF_LOG_DEFERRED 1 
 Another words - bigger log buffer than 4 bytes can not be sent at once. Thus, you have to enable deferred logger. In my opinion there should be suitable comment in cli example above the lines: 
 /** @brief Command line interface instance. */
#define CLI_EXAMPLE_LOG_QUEUE_SIZE (4) 
 Best regards,
