BLE4.2 and iPhone 7 throughput, PDU, packets per event and conn interval

Hi, I can see that Apple states that iPhone 7 supports LE Data Packet Length Extension forums.developer.apple.com/.../73168. Anyone know if the packets per event and the connection interval is different on the iPhone7 ? I am trying to calculate the potential througput i can get from this iPhone model.

Yes, it is different. And the behavior might change depending on the iOS version as well. This also depend on whether the peer support DLE or not. iPhone 7 iOS 10.0.3, peer Without DLE: ATT MTU size…

Hi, Thank you for your reply, if i connect with an nRF52 to an iPhone 7 then what can i theoretically expect, i am not sure i follow your data given above. Let's assume that i enable DLE on the nRF52 and i use the iPhone 7 with iOS10. I use 6 events per interval of 30ms (but this is where i don't know if i could go lower like 7,5ms, does iPhone7 support that do you know ?) and a payload size of 251bytes so theoretically the speed should be 6 * 251 * 1/0.030=50,2kB per second or 401kbps, is this correct ?
