https://devzone.nordicsemi.com/f/nordic-q-a/25207/nrf_log-and-uart-not-working-simultaneouslyHi, I am using experimental_ble_app_blinky example. In that NRF_LOG over UART was implemented. I Added some UART code for my use. But after flashing code was not working at all. Printf and NRF_LOG_INFO was not working simultaneously.

I would ask you to take a look at <a href="https://devzone.nordicsemi.com/question/166674/problem-with-adding-uart-to-print/?answer=168351#post-id-168351">this answer</a> again. It covers exactly what you need do to, what modifications you need to make to the sdk_config.h file, and what files to add to your project. It also has example files you can take a look at. Please let me know if you have any questions regarding this.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/99351?ContentTypeID=1Tue, 19 Sep 2017 15:38:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c2a7a28d-5750-4804-b6b0-4a7dd212461dphob<p>Thanks Joakim. i don&#39;t required NRF_LOG, so i have removed all the NRF_LOG_xxxx calls from files. But now i am facing problem like printf is not at all working and processor gets stuck there only. But i could use uart_put_char to send single character. i have attached sdk_config.h file.</p> <p>[sdk_config](<a href="https://drive.google.com/file/d/0B6CAhHiAfKJkTGVrV1FDVVBDZzQ/view?usp=sharing">file</a>)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/99349?ContentTypeID=1Mon, 18 Sep 2017 13:56:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5c6d0ab6-f286-4096-9744-f8a3619909e3Joakim Jakobsen<p>Hi Phob!</p> <p>Please take a look at <a href="https://devzone.nordicsemi.com/question/166674/problem-with-adding-uart-to-print/">this thread</a>.

Even if i use printf then also application is not working properly. i think there might be nrf_log task is running. Which might using UART service. What could be other possibilities?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/99347?ContentTypeID=1Fri, 15 Sep 2017 16:44:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:82e3a538-fb60-4596-9123-475b3f04eaf7phob<p>I am using SDK v12.2. Softdevice is S132 and NRF52 Board. Also Board is restarting continously. i disabled NRF_LOGs and Changed it to printf. I changed to LOG over RTT instead of UART. I have updated my files on github. <a href="https://github.com/embhobbb/multinode/">github.com/.../</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/99346?ContentTypeID=1Fri, 15 Sep 2017 00:38:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e183c02f-e826-4ad1-a1e0-4775c3c82a630xDC<p>What SDK version?</p><div style="clear:both;"></div>
