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 > On Jan 21, 2016, at 6:56 AM, Arun Nedun <arun(a)visybl.com> wrote: > > Hello All, > > We are currently working on BLE communication between our BLE beacon and iOS.

Storing BLE Chars so that we can write value fast
by Arun Nedun 21 Jan '16

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?

That's exactly what we did. What I saw here seemed to conflict with what Apple told us. Thanks for the clarification. I'm relatively new to this list. Is this list only for Core Bluetooth and not classic devices?

Is this LE, classic, or both? I ask because we have a (classic mode) MFi peripheral that tries to be connected to the app constantly. In order to achieve this the peripheral has to periodically attempt re-connect to the app. This seems to suggest that connections from the app to the peripheral may be possible after the device has been bonded. We would much prefer that if the peripheral has already been bonded to the phone that the app tries to automatically connect to the device if its not already connected.
