3.1 About Operating Modes
During operation, kDynamo transitions between distinct modes, each of which behaves differently:

Reset Mode occurs when the user presses and the recessed reset switch. After resetting, the device
progresses to Powered Off Mode. If the device is connected to USB power, it immediately
progresses to Idle Mode.

Powered Off Mode is the shipping mode of the device. The operator can power off by holding the
pushbutton for 2 to 3 seconds. The device also enters this mode automatically if it has been in Sleep
Mode for a configurable timeout period. When powered off, the device consumes practically no
power. To move the device from Powered Off Mode to Idle Mode, press the pushbutton briefly or
connect the device to USB power. When the device is connected to USB power, the device
immediately progresses to Idle Mode.

Idle Mode is the device’s normal waiting state. The operator activates this mode by briefly pressing
the pushbutton once while in Powered Off Mode, or connecting the device to USB power. In this
mode, the device is ready to connect to an iOS host. If the device is not connected to USB power, it
will move from Idle Mode to Sleep Mode automatically when its configurable timeout period has
passed. kDynamo automatically progresses from Idle Mode to Connected Mode when the iOS host
has established an iAP2 session.

Connected Mode occurs when the iOS host has established an iAP2 session with kDynamo. In this
mode, the host and the device can both initiate communication. It is the host’s responsibility to
terminate the iAP2 session and send the device into Sleep Mode to save power when an active data
connection is no longer needed. If the device is not connected to USB power, it will automatically
move from Connected Mode to Sleep Mode when its configurable Sleep Mode timeout period has
passed. Doing so does not automatically or immediately terminate the iAP2 session with the host.

Sleep Mode is a low-power standby state. The host initiates this mode by closing its iAP2 session
with the device, which generally happens automatically when the host enters sleep mode, and may
also be initiated directly by the host software. The device also enters this mode automatically when it
is not connected to USB power and has been unused (no user input, no communication with the host)
for a configurable timeout period. Operators can move the device from Sleep Mode to Idle Mode by
pressing the pushbutton briefly or connecting the device to USB power. The host can move the
device from Sleep Mode to Connected Mode by opening an iAP2 session. The device automatically
moves from Sleep Mode to Powered Off Mode when its configurable Power Off timeout period has
passed.
