Still confused about how fast you can really send data over Bluetooth Low Energy v.4.x (BLE) ?

A google search will turn up many incomplete answers.
Each OS and device has it’s own restrictions, such as connection interval and number of packets per interval.
For example, did you know that with iOS you can send 4 packets per interval, and that HID devices can communicate 2.6x faster ?
If you want to finally clear up how fast you can communicate over BLE with an iPhone, Android device, or Mac, read on.
