https://devzone.nordicsemi.com/f/nordic-q-a/22474/why-nrf_log_info-is-going-crazyI think I found the source of many of my recent problem. The print in Segger is going crazy. I found out that if I increment a simple variable and print it when I hit debug and run ( then play button), they system will skip or stop in the middle : en-USTelligent Community 13Thu, 01 Jun 2017 08:21:53 GMThttps://devzone.nordicsemi.com/thread/88352?ContentTypeID=1Thu, 01 Jun 2017 08:21:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df55d3fc-b71e-4280-a0a2-014d58ab7b70Lola<p>Thank you ! I wonder why am I the only one at least at Google, to having this kind of problems :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88351?ContentTypeID=1Thu, 01 Jun 2017 05:45:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a55cc1a-0be6-48b9-be30-dc672f3b83dfKrzysztof Chruscinski<p>You can also try to increase logger buffer size (NRF_LOG_DEFERRED_BUFSIZE in sdk_config.h). This is the buffer which holds log entries before they are processed and send to the host (NRF_LOG_PROCESS, NRF_LOG_FLUSH). But as Jorgen mentioned it can be that RTT is losing the data because it is not able to process.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88350?ContentTypeID=1Thu, 01 Jun 2017 05:36:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0305f870-ea3c-4c1b-a37f-f1727ab5fad8J&#248;rgen Kvalvaag<p>NRF_LOG is non-blocking so, as @Turbo J mentioned, by default it will skip if there is no space in buffer.</p> <p>You can configure thisbehaviour in sdk_config.h. Look under nRF_Segger_RTT -&gt; segger_rtt -&gt; SEGGER_RTT_CONFIG_DEFAULT_MODE, you can change it to BLOCK_IF_FIFO_FULL.</p> <p>This way you should be able to print whatever you want without inserting delays.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88349?ContentTypeID=1Wed, 31 May 2017 20:22:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c04fb343-98d0-4bc0-a8bc-be187dde65fcLola<p>Yea well I went with delay. thanks a lot.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88348?ContentTypeID=1Wed, 31 May 2017 20:06:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e5cf663b-5fef-466c-8d9e-a1221cce2fa7Lola<p>@Turbo J Not sure I get it, so how to solve this and be able to print what ever I want ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88347?ContentTypeID=1Wed, 31 May 2017 20:05:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:616fee68-3cf5-4d64-98e4-172318854583Turbo J<p>NRF_LOG_* functions like to skip messages when there is no buffer space available.</p><div style="clear:both;"></div>
