I am developing a scheme where the nRF51 (central role) connects to iOS device (peripheral roles). The nRF51 connects, performs the discovery procedure and interacts with desired characteristics.

thank you for the reaction. I&amp;#39;ll try to determine which peer terminates the connection. Connection parameters are set by Central (nRF51) and they are always the same.&lt;/p&gt;

&lt;p&gt;It seems to be working fairly well for me. Do you have RF trace from these failures to analyze what are connection parameters and which peer disconnects (through LL_TERMINATE or through timeout)?&lt;/p&gt;
&lt;p&gt;Cheers Jan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
