Hi Nordic Forum!
In the past, I set connection interval min to max is 20ms~75ms, it work ok for IOS。But on Android platform, Android use 75ms as actual connection interval. It is too long for us. We need change connection interval to reduce delay. So we try set connection interval to 15ms~30ms、15ms~15ms、20ms~30ms and so on,but use all these param , connection will disconnect after about 90s for iOS.
I referennce the Apple develop guidlines section 23.6(https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf)。
Follow that,the connection interval range15ms~15ms、15ms~30ms is ok。I don't know why occur exception disconnect on IOS platform.
What value should I set to connection interval ensure work on IOS.
