https://devzone.nordicsemi.com/f/nordic-q-a/20368/nrflogger-reducing-overhead-in-log-filesWe are currently trying to log our sensor data to a mobile phone through uart using nrfLogger app. We have nrf51 module and we are using SDK 12. In nrfconnect, we select the APP logging, however for every data sample info log(I) also comes along whenen-USTelligent Community 13Mon, 13 Mar 2017 16:08:18 GMThttps://devzone.nordicsemi.com/thread/79398?ContentTypeID=1Mon, 13 Mar 2017 16:08:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6571cb44-4287-427d-9cb0-c47aa2250eacHung Bui<p>I haven&#39;t used the API my self, but I assume, what the API does is to send data to the nRFLogger application. You will have to save log into file from inside nRFLogger app.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/79397?ContentTypeID=1Mon, 13 Mar 2017 14:05:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d49891bc-272e-4e60-93d2-d5020d0b78b6raju<p>Thank you Hung Bui, we will create our own application and try. By the way can we save log data using this API? Since the nRFtoolbox and nRFUart applications dont have option to save data.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/79399?ContentTypeID=1Mon, 13 Mar 2017 11:17:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bfc64602-ea38-446c-9fb9-426e9fda0855Hung Bui<p>Hi Raju,</p> <p>It&#39;s not possible with nRFConnect to customize the log for now. My suggestion is to create your own application (maybe base on our nRFtoolbox or nRFUart) and you can customize your blog. The logger API provided here: <a href="https://github.com/NordicSemiconductor/nRF-Logger-API">https://github.com/NordicSemiconductor/nRF-Logger-API</a></p><div style="clear:both;"></div>
