https://devzone.nordicsemi.com/f/nordic-q-a/114330/command-line-interface-data-validation-nrf5-sdkI&#39;m using the CLI interface through USB and UART, and I am wondering if there are any innate methods for checking the validity of the data being sent and received via the CLI. For example, is there a method to append a checksum to each CLI output, anden-USTelligent Community 13Fri, 30 Aug 2024 10:35:50 GMThttps://devzone.nordicsemi.com/thread/500553?ContentTypeID=1Fri, 30 Aug 2024 10:35:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c21eee1e-5f36-4436-a38a-98e00cfa2c71Simonr<p>Hi</p> <p>There is no innate method for data validation in the <a href="https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/lib_cli.html">CLI library in the nRF5 SDK </a>AFAIK, but I will ask some of the old trotters internally if they&#39;re aware of something. I&#39;ll let you know if I hear back, but I wouldn&#39;t hold my breath waiting for an update unfortunately.</p> <p>One thing could be to use the parity bit on the UART for validating the data, as something like CRC/checksums is not something we have in the nRF5 SDK.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
