Lost LOGs - increase LOG backend queue size.

[Dusan Daniska]

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.

Hello,
I have the same problem. Is there any known solution which won't affect whole sdk_config.h file?

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)

Thank you very much!
