Connection interval in Android 6

[Antonio]

Hi!

I am using the NUS service and I noticed that Android 6 (Marshmallow) will not go faster that 47.5 ms. Even iOS can go to 30ms. My target is 7.5.

Am I doing something wrong? Anyone has some advice?

Thanks!

Hi,

The minimum connection interval is highly dependent on the hardware present in your mobile phone. Please see this thread for some examples. For further information you can see this answer and the blog on how different BLE packet types influence throughput.

While the nRF family is capable of 7.5 ms connection intervals, most mobile phones are not.

Best regards,

Øyvind
