https://devzone.nordicsemi.com/f/nordic-q-a/66956/nrf52840-zephyr-sscanf-issueTo parse information from strings I want to use sscanf(). Currently I have this small test program: And in the prj.conf I have CONFIG_NEWLIB_LIBC=y defined. This program produces two different outputs: Zephyr: onlinegdb: What is going on hereen-USTelligent Community 13Mon, 12 Oct 2020 15:05:27 GMThttps://devzone.nordicsemi.com/thread/274396?ContentTypeID=1Mon, 12 Oct 2020 15:05:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11fd9070-67cf-4031-88c8-1cd3f90fcaa7Didrik Rokhaug<p>Hi,</p> <p>It&#39;s good to hear that you found a solution.</p> <p>You can also set CONFIG_NEWLIB_LIBC_NANO=n to get the full version of Newlib, and not just the &quot;nano&quot; version. That will also make your test program work as expected.</p> <p>Best regards,</p> <p>Didrik</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/274180?ContentTypeID=1Mon, 12 Oct 2020 06:18:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a9fb45f-227a-4e1d-9065-ac1f08526dc5newUser<p>I have replaced %hhu with %u, and made socket a uint32_t. This solved it.</p> <p>Does the sscanf() implementation on this platform not support smaller types?</p><div style="clear:both;"></div>
