Try to prevent messages from being chopped up into multiple notifications Read data into a buffer and only send a notification when 250ms have passed since the first read instead of sending a notification immediately after each read. This is an attempt to prevent messages from being chopped up into multiple notifications. A (rather negligible) downside of this approach is that multiple messages rapidly following each other are coalesced into a single notification.
