I used bluetooth as a peripheral to advertising and my production as a central.
In iOS12, The advertising interval is 30ms, but In iOS13, the advertising interval is 180ms.
One iPhone, different system. advertising interval is different. It make my production can not discover iPhone.
I do not kown how to do it.
I encountered the same issue, I found different devices has different performance.
iPhone SE iOS 13.1 180ms
iPhone 6s iOS 13.2 30ms
iPhone X iOS 13.2.2 30ms
Do you have any solution to speed up the advertising interval?
