Notification frequency capability

[simonebusoe]

Hi, i found this library very useful and very well done.

I am trying to get notification from one or two BLE server that are capable to notify at 64Hz. Using BLE_client example as a template i only get a maximum of 14 notification per seconds for each server i am subscribed, as each callback or each couple of callbacks are fired every 67ms.
Does anybody know if it's possible to push a bit more the amount of notification we can get in a second? My goal is 25 or 50 Hz.

Thank you in advance.
