It is also stated in the Bluetooth Core Spec v5.0, section 3.4.2.1 Vol. 3 Part F that the MTU size shall only be sent once during a connection.&nbsp;</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/230960?ContentTypeID=1Sat, 25 Jan 2020 03:04:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1f8bf2a5-d72f-4770-97ef-c7daf8c4d7deox00<p>I just want it to have a stable connection and resolve the error that displays.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/230855?ContentTypeID=1Fri, 24 Jan 2020 12:53:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d425d298-cf90-48c0-a87c-5b7522babe69Simonr<p>Hi</p> <p>The reason you&#39;re seeing this error is that the SoftDevice on the nRF side only allows one MTU request. I&#39;m having some trouble understanding what it is you want to achieve with your application, so please explain in more detail.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
