https://devzone.nordicsemi.com/f/nordic-q-a/114066/nrf51822-uartI am using the serial port of SDK7.1 to send and receive data, and this serial port is a serial port of nRF51_SDK_7.1.0\examples\peripheral\uart\pca10028\arm. Can this serial port be transplanted into the project? Why do I port it to the serial port,en-USTelligent Community 13Thu, 22 Aug 2024 11:58:39 GMThttps://devzone.nordicsemi.com/thread/499367?ContentTypeID=1Thu, 22 Aug 2024 11:58:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c2f1ecee-2107-4cf0-84e5-8621bcda868dH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>Does this mean that you solved your issue?</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/499282?ContentTypeID=1Thu, 22 Aug 2024 01:28:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:32353c45-50b6-4803-a74e-63021a1fb051liuyanfeng<p><strong>I know what the reason is, the simple serial port failure in SDK7.1. It turns out that sending and receiving need hexadecimal, and the introduction is also wrong.
