https://devzone.nordicsemi.com/f/nordic-q-a/10513/connection-interval-errorsHi I&#39;m trying to optimize my connection interval for latency vs power consumption but I notice that a lot of values I try to set are giving me the invalid parameter error after calling sd_ble_gap_ppcp_set(). What&#39;s strangest to me is if I set bothen-USTelligent Community 13Fri, 27 Nov 2015 18:14:59 GMThttps://devzone.nordicsemi.com/thread/39094?ContentTypeID=1Fri, 27 Nov 2015 18:14:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:631c2aa2-dcb4-407f-bb1f-395d18039f92danbujak<p>I ended up using the template format to set them and it seems to be working now- not sure what was wrong.

Are you using an example? Changing the connection parameters to Min = 200ms and Max = 300ms in ble_app_template example in SDK 10 with Softdevice s110 v8.0.0 did not produce any errors.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/39095?ContentTypeID=1Fri, 27 Nov 2015 08:01:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa5ed7d2-4df1-436f-beb9-4c6547e4450aGustavo - Argenox<p>Hi danbujak,</p> <p>You haven&#39;t stated what is the other device in the connection, and this matters a lot. For example, iOS will not allow 7.5ms connection interval while Android will. Every stack is different.</p> <p>There should not be an issue to set connection interval of 200 to 300 since the devices negotiate, but this can depend on the second device and what it is willing to accept.</p><div style="clear:both;"></div>
