You cannot store the characteristics in your app, and they must be discovered every time you connect. If the OS determines the characteristics on the device are safe to cache, it will return a cached copy after a reconnect. - Craig

Hello All,

We are currently working on BLE communication between our BLE beacon and iOS. I was able to successfully write Chars. value based on user action on the App. However it is not instantaneous. To conserve battery on the BLE beacon side we have kept the connect interval window very small. So when the user presses the button, there is a lag in connecting and writing the value.

What i need to know is, during the first scan, can I store the chars. on the App so that when i want to write Chars. I don’t have to discover it instead i can directly write Chars?

Thanks Arun
