https://devzone.nordicsemi.com/f/nordic-q-a/77261/config-mtu-problem-on-ncs-v1-6-0Hi, I got an issue when setting these configurations on the new NCS v1.6.0: It has worked well on v1.5.1. Thank you, Nhuanen-USTelligent Community 13Tue, 23 Nov 2021 15:15:18 GMThttps://devzone.nordicsemi.com/thread/340397?ContentTypeID=1Tue, 23 Nov 2021 15:15:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a2af6a39-8a62-478d-a9d9-4b23ed343697Rafael Daciuk<p>Hi Heidi,</p> <p>Thank you for this info, I was struggling with the same issue.</p> <p>I have one question though. Whenever there is an update like this, where can I find details about changes that will break our code? I have been looking at release notes and such, but I could not find anything about this there by searching the config parameters that no longer work.</p> <p>Best regards,</p> <p>Rafael</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/319811?ContentTypeID=1Tue, 13 Jul 2021 13:09:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:090faa3a-584a-412a-8a00-51f1b7c3ffe5Nhuan<div class="content full threaded-reply-content user-defined-markup"> <div class="content"> <p>Thank you very much, it worked for me.</p> <div></div> </div> </div><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/319753?ContentTypeID=1Tue, 13 Jul 2021 10:31:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ecf8f0e1-8dfb-4699-ab98-3ce16156fb93Heidi<p>Hi!</p> <p></p> <p>The second config,&nbsp;BT_L2CAP_RX_MTU, has been removed in NCS v1.6.0 with this <a href="https://github.com/nrfconnect/sdk-zephyr/commit/6483e12a8ac4f495b28279a6b84014f633b0d374#diff-bc5547b4023cdb1ca08639c2640be7283e97dc3bc221c32a993606b66b265956">commit</a>.</p> <p></p> <p>The new configuration is BT_BUF_ACL_RX_SIZE, which is just BT_L2CAP_RX_MTU plus the L2CAP PDU header size of 4 bytes.&nbsp;</p> <p></p> <p></p> <p>Best regards,</p> <p>Heidi</p><div style="clear:both;"></div>
