I am Having issue with using the changeKey method in the taplinx sdk, i created an application using the default card key and now i want to change the key. But the changeKey method is not able to effect the change, what might i be doing wrong. Kindly assist, a code snippet will be much better. Thank you</P> Tue, 15 Oct 2024 10:56:12 GMT https://community.nxp.com/t5/TapLinx-SDK-TagWriter-and/Default-EV3-card-Key-change/m-p/1974213#M38 felixyoma4u 2024-10-15T10:56:12Z https://community.nxp.com/t5/TapLinx-SDK-TagWriter-and/Default-EV3-card-Key-change/m-p/1981753#M44 <P>Dear felixyoma4u,</P> <P>Please provide your code snippet at the position where you would like to change your key.
