NRF log RTT small buffer size when device is disconnected

[vitaliy2034]

When I reset the device and in some time connect it to JLinkRTTViewer, it shows only 11-12 first messages after the reset. Which parameter I should change to increase number of messages? I use in-place processing, RTT backend and NRF_LOG_ALLOW_OVERFLOW are turned on.

Hello, I have found parameter in sdk_config.h which response for buffer size: SEGGER_RTT_CONFIG_BUFFER_SIZE_UP .

But RTT behavior if the buffer is full supports next modes(Parameter SEGGER_RTT_CONFIG_DEFAULT_MODE):

SKIP  - Do not block, output nothing.
TRIM  - Do not block, output as much as fits.
BLOCK - Wait until there is space in the buffer.

How to use NRF_LOG_ALLOW_OVERFLOW, I don`t know.

What do you have 'SEGGER_RTT_CONFIG_DEFAULT_MODE' set to? Our SDK examples use SKIP.
