I know that iOS7 has introduced caching mechanisms in the CoreBluetooth.
1. I reconnect to a previous connected device with the peripheral identifier.
2. Connection is fast (100ms)
3. I need to read a characteristic value
- Is it mandatory to discover services and characteristics before reading a value ?
In my case it takes 1.5s to read the value ?
- Can I save a characteristic and use this property without services and characteristics discovering step ?
Is the iOS7 caching mechanism « transparent » / « free » meaning that discovering services and characteristics is using cache ?
