NOTE – It is recommended that the hexadecimal representation used in all human-readable formats be restricted to lower-case letters. Software processing this representation is, however, required to accept both upper and lower case letters as specified in 6.5.2.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73983?ContentTypeID=1Thu, 19 Jan 2017 21:28:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:67a08319-e971-44dd-b6b1-d0508466137cSRA<p>NRF Connect should know to display that as uppercase fwiw...</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/73982?ContentTypeID=1Thu, 19 Jan 2017 18:18:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ae3e84ee-451f-412d-b11b-dde57dcfd093Sigurd<p>Hi,</p> <p>Q: Is lower-case UUID a problem?</p> <p>A: No. A UUID is a 128-bit value, and what you see is just the hexadecimal representation of that 128-bit value. It’s not text (string/character), i.e. its not case sensitive.</p><div style="clear:both;"></div>
