AFAIK it&#39;s not something defined in the Bluetooth spec, if it is please let me know. Maybe they were talking about the slave latency ? And the L2CAP connection parameter update request ?</p> <p>I haven&#39;t seen Android device rejects the first connection parameter update request but accept the second one. I need a sniffer trace to verify this.</p><div style="clear:both;"></div>
