Hi, All

Just wonder how to view the log info like below, it is used in peripheral uart example.

LOG_DBG("tx_done");

which config/tool allow this please?

Thanks!

Hi Ping,

To get debug logs you must set the log level to the highest level. You can find more information about the logging here: Logging in nRF Connect SDK and Zephyr Logging.

Additionally, in the Peripheral UART sample logging is done over RTT and not UART, since UART is used for other things, so you must use RTT Viewer to view the logs as explained here: How to use RTT.

Best regards,

Hi, Marte

Thanks for reply.

For this particular example - the peripheral UART, I can see the RTT log like below

"LOG_INF("Received data from: %s", log_strdup(addr));"

and also I opened a UART terminal to receive/send some message over UART, but I cannot see the LOG_DBG info like 

LOG_DBG("rx_rdy"); etc.

Please help!

Hi Ping,

As I said in my previous reply you must set the log level. You can set the default log level to debug by adding the following to prj.conf:

CONFIG_LOG_DEFAULT_LEVEL=4

Thank you, I see it now!

On a separate question, both central and peripheral uart examples keep crashing when message is slightly long, any solution to this?

Thanks

Hi Ping,

Please open a new ticket about this as it is not related to the original question in the ticket.
