https://devzone.nordicsemi.com/f/nordic-q-a/46056/usage-of-rx-tx-pins-in-meshHello to everyone. I&#39;m working with chip nRF52832 (PCA10040) and Mesh 3.1. I&#39;m trying to connect a HC-05 Bluetooth/Serial Module using its serial pins (Rx/Tx) to the default serial pins from the board: Tx (P0.06) and Rx (P0.08), but I don&#39;t know howen-USTelligent Community 13Thu, 18 Apr 2019 21:56:41 GMThttps://devzone.nordicsemi.com/thread/182780?ContentTypeID=1Thu, 18 Apr 2019 21:56:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7c0ed1e0-7395-445c-bcf8-115f6d436b7dJK0201<p>Thank you a lot!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/182157?ContentTypeID=1Mon, 15 Apr 2019 14:35:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:13e59ff4-ad47-42e1-8b8b-47d5588c20cbhaakonsh<p>You might have to add the UARTE drivers and serial library if you want to use it, see SDK\examples\peripheral\serial_uartes with the&nbsp;<a title="Serial port library" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/lib_serial.html?cp=5_4_0_3_41">Serial port librar</a>y + <a title="Serial port abstraction layer" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/group__nrf__serial.html?cp=5_4_0_6_11_41">Serial port abstraction layer</a>&nbsp;API,&nbsp;or \uart with the <a title="UART" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/hardware_driver_uart.html?cp=5_4_0_2_0_19">UART</a>&nbsp;driver +&nbsp;<a title="UARTE" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/group__nrf__uarte.html?cp=5_4_0_6_9_0_31">UARTE</a>&nbsp;driver API or&nbsp;<a title="UART module" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/group__app__uart.html?cp=5_4_0_6_11_57">UART module</a>&nbsp;API.<br /><br /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/181628?ContentTypeID=1Thu, 11 Apr 2019 13:22:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:af1e6512-b2b7-4557-82c4-2548fdec1727JK0201<p>Hello, haakonsh. Thank you for your answer.<br />Ok, that could be assigned on pca10040.h, I suppose.<br />There are specific paths or libraries that I have to add to the light_switch project? or the project runs the Rx/Tx functionality already?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/181551?ContentTypeID=1Thu, 11 Apr 2019 11:13:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d269c885-d3e2-4974-9bc4-e181811b59fbhaakonsh<p>The default tx/rx pins are connected to the J-link debugger, you need to change the tx/rx pins to another set of gpios.&nbsp;</p><div style="clear:both;"></div>
