Abstract
An input device detects a key press or release and when the same key has not been pressed or released since a last acknowledgement, a no-acknowledgement packet with key data for that period and any other key data since the last acknowledgement is wirelessly transmitted to the host. When the same key has been pressed or released since a last acknowledgement, an acknowledgement request in a packet with key data for that period and any other accumulated key data is wirelessly transmitted to the host. At a maximum delay time without requesting an acknowledgement, an acknowledgment request packet is transmitted. At a threshold number of key events, an acknowledgment request packet is transmitted.
