https://devzone.nordicsemi.com/f/nordic-q-a/27417/how-to-disable-aes-encryption-while-pairingHi there, I&#39;m currently porting the nRFgo gzll_host_w_dyn_pairing_example however my microcontroller does not have an aes encryption peripheral. It seemed easy to just define GZP_CRYPT_DISABLE but this results in undefined reference errors &#39;gzp_crypt_user_data_receiveden-USTelligent Community 13Tue, 21 Nov 2017 09:58:15 GMThttps://devzone.nordicsemi.com/thread/108285?ContentTypeID=1Tue, 21 Nov 2017 09:58:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b906bbd3-233e-4c8b-99d7-51f5107666c2Hung Bui<p>Hi Taxara,</p> <p>If you don&#39;t plan to use any encryption, can you simply use the gazell link layer, instead of using gzp ?</p> <p>In addition, I&#39;m not really sure you need to define GZP_CRYPT_DISABLE . If you use normal GZP but don&#39;t use encrypted pipe, and stick to the plaint text pipe (pipe2) wouldn&#39;t it work ?</p><div style="clear:both;"></div>
