iOS Compatibility

[Gilson]

Hello Guys,

I'm about to start my first BLE iOS project and I was wondering if there are any compatibility issues or anything that I should be aware between nRF51822 and iOS using a custom profile.

The application consists of nRF51822 sensor board sending accelerometer and other telemetry data to the iOS. The user may have an old iPhone 5 or latest iPhone 6 and the same for iPads so I have no control over the user version but I could recommend an upgrade if I know what I'm looking for.

On the Nordic side, I'm going to use S110 v7.x and SDK 6.x in another words the latest Nordic code.

Please share your iOS experience with me if you can.

Thanks a lot,

Gilson

There are connection parameters from Apple that you must follow, otherwise the iOS device might drop its connection to your board. Apple also provide recommended advertising intervals.

In terms of compatibility with custom profiles, the only thing I've seen in the past was that iOS doesn't work well if you try to Write-with-response to a characteristic that is Write-without-response. And vise versa. Android doesn't care as much about this alignment, but iOS does.

I've noticed the same thing about trying to do things you "shouldn't" with IOS.
