https://devzone.nordicsemi.com/f/nordic-q-a/32082/sending-raw-data-through-uart-using-nrf_logHello, For my project I need to send raw data (without prefix or timestamps ) along with system logs trough the same UART. So far one possible solution is to use NRF_LOG_RAW_INFO, e.g.: The question is whether this will be efficient enough anden-USTelligent Community 13Wed, 14 Mar 2018 08:21:12 GMThttps://devzone.nordicsemi.com/thread/124291?ContentTypeID=1Wed, 14 Mar 2018 08:21:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd45ebe5-7152-4bbf-86ff-2bcc5106dd55Jakub Rzeszutko<p>Hi kont40,</p> <p>If you need Logger functionality proposed macro is fine. If you would like to print logs and process some text from the user you can be interested in CLI module. It allows to print text either by NRF_LOG_RAW_INFO or by the function nrf_cli_fprintf.</p> <p>If you need a simple message printer without logger and console you can use nrf_fprintf module.</p><div style="clear:both;"></div>
