https://devzone.nordicsemi.com/f/nordic-q-a/33452/data-througput-ios-androidI have a general question for customers regarding throughput. What&#39;s the maximum data througput with IOS without a MFI Chip. Which profile do I have to use. Supports IOS 2Mbit? Which data throughput can be achieved with Android? Thanks &amp; besten-USTelligent Community 13Mon, 16 Apr 2018 16:47:23 GMThttps://devzone.nordicsemi.com/thread/128526?ContentTypeID=1Mon, 16 Apr 2018 16:47:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e71fd097-31fe-4faf-a48e-00e1ea568414awneil<p>I know nothing about iOS, but with Android it depends on the particular device and how it is feeling at the time. Possibly also the phase of the moon.</p> <p></p> <p>During connection, the peripheral requests a set of Connection Parameters - which set the maximum throughput.</p> <p>But the Android device may not accept the requested parameters and, instead, give something &quot;slower&quot;.</p> <p></p> <p>I have not seen any rhyme nor reason in whether Android does or does not accept a particular set of Parameters - sometimes just disconnecting &amp; immediately reconnecting will give a different result!</p> <p>And it is different for different Android versions!</p> <p>eg,&nbsp;<a href="https://stackoverflow.com/questions/34617061/android-6-0-marsmallow-ble-connection-parameters">stackoverflow.com/.../android-6-0-marsmallow-ble-connection-parameters</a></p> <p></p> <p>You&#39;re going to have to search Android &amp; iOS documentation for answers ...<br /><br /><br /></p> <p><a href="https://developer.android.com/guide/topics/connectivity/bluetooth-le.html">https://developer.android.com/guide/topics/connectivity/bluetooth-le.html</a></p> <p></p> <p><a href="https://developer.apple.com/library/content/qa/qa1931/_index.html">https://developer.apple.com/library/content/qa/qa1931/_index.html</a></p> <p></p> <p></p><div style="clear:both;"></div>
