TI BLE 1.4.0 Stack Allows for Increased Throughput

This feature will be very useful. Have you ever tested this feature (overlapped processing) on any iOS devices? 

Im also interested about iOS7 supporting this or not. Has anyone tried?

I really needed to know about ios supporting this feature. My colleague and I implemented the overlapped processing on sensor tag device but we can see by oscilloscope that this feature is not helping us to get a faster application for dynamic purposes. We can send at maximum six pairs of Tx and Rx. Can you please tell a little bit more about it?

Yes this is correct.  iOS currently has a limit of 6 packets per connection interval.

Thanks a lot, Tim, for your quick response. Also, do you know if the minimum connection interval between connection events is around 30ms? Because we can't get minor values for this.

Hi.  The minimum connection interval when connecting to an iOS device is 20 ms as defined in the Bluetooth Accessory Design Guidelines for Apple Products:  https://developer.apple.com/hardwaredrivers/BluetoothDesignGuidelines.pdf

Hi Valeria,

Not that you cannot set connection parameters from the iOS device itself although you can request from the connected peer device (i.e. our C254x). The request for connection parameter update includes the "minimum connection interval" as low as 20 ms but note that you must also include a "maximum connection interval" of more or equal to "minimum connection interval" + 20 ms. The result is that the iOS device is free to choose a connection interval between 20 ms and 40 ms... I'm sorry to say that it usually chooses 30 ms.

Best Regards

Joakim
