NRF52 uart example is not transmitting but receivinghttps://devzone.nordicsemi.com/f/nordic-q-a/92891/nrf52-uart-example-is-not-transmitting-but-receivingI am using the NRF52 development kit and I modified the uart example main.c to simple TX and RX application using printf function. The board is directly connected to the PC with the USB. I used x3 different serial applications on the PC, which are Puttyen-USTelligent Community 13Mon, 17 Oct 2022 08:58:36 GMTRE: NRF52 uart example is not transmitting but receivinghttps://devzone.nordicsemi.com/thread/390924?ContentTypeID=1Mon, 17 Oct 2022 08:58:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d202c606-4364-404b-81a4-f642270dd48cJ&#248;rgen Holmefjord<p>Hi,</p> <p>Not sure if I missed something in your application or case description, but if you have removed retarget.c from your project, I would not expect printf to output anything to UART. retarget.c is the place where printf statements are forwarded to UART using app_uart_put() function, so unless you have implemented this somewhere else, the printf statements will not go anywhere.</p> <p>I would highly recommend you to stick with the SES version used for testing/verification of the SDK version you are using, mentioned in the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/index.html">release notes</a>. the STDIO retarget layer should work with the older SES version.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>RE: NRF52 uart example is not transmitting but receivinghttps://devzone.nordicsemi.com/thread/390861?ContentTypeID=1Sat, 15 Oct 2022 08:24:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6cde0949-d774-44a3-bd6f-74ba930a0f49MRK-196<p>I forgot to mention that I am using the PCA10040 chip.</p><div style="clear:both;"></div>
