- Can I save a characteristic and use this property without services and characteristics discovering step ?

No. CBService/Characteristics/Descriptors are only valid within the context of the connection in which they were discovered.

You need to go through the same steps and the cache will be used where appropriate.

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 ?

Is the iOS7 caching mechanism « transparent » / « free » meaning that discovering services and characteristics is using cache ?
