9.1.9
UART
The physical UART can be enabled/disabled with a custom baud rate and configured to use available GPIOs for its
transmit and receive pins.
The UART currently only supports disabled and enabled modes of operation, where the receive line is always powered
and listening.
9.1.10 GPIO Events
Transmit Queue events can be sent via URCs to indicate asynchronous events that are occurring, and can be very useful
for debugging.
9.1.11 Inputs
8 software inputs are available that can be used for count and accumulate functions on physical GPIOs, accelerometer
events, and other abstracted event types.
GPIOs configured as inputs and special functions can be mapped to software inputs.
9.1.12 OTA Messages
OTA messages can include count, accumulate, undesired state, and transition events from inputs that support both open
and closed states. Inputs that are based on singular events (where there is only an active state), will only support count
and transition events.
Mod Msg Input Config 1-8 OTA messages make it possible to describe inputs and inputs states through OTA messages.
Up to 64 bytes of user-defined payload can accompany OTA messages when utilizing Modular Msg Input Config 1-8 OTA
profiles (See Messages section).
9.1.13 Input Events
Input events can be sent via URCs to indicate asynchronous events that are occurring and can be very useful for
debugging.
9.1.14 Track Functions
Supported track modes include the following:
9.1.14.1 Normal Track Mode
In Normal Track Mode, location updates are sent periodically based on the at-rest update interval setting when the unit is
"At-Rest", and at the in-motion update interval when the unit is "In-Motion".
Power states can reduce the in-motion reporting interval (see Power Management).
9.1.14.2 Dock Mode
Dock mode is similar to Normal Track Mode, however, requires the accelerometer to report In-Motion based on the
continuous-vibration and continuous-lacking-vibration settings as verification for movement in addition to the GPS's
change-of-location event. This track mode adds resiliency by utilizing two sources for movement verification.
9.1.14.3 Theft-Alert Mode
Theft Alert mode creates a geofence around the device after power-up.
If inside the geofence, OTA position messages are sent the same as in Normal Track Mode.
If outside the geofence, OTA position messages are sent more frequently at the in-motion interval.
9.1.14.4 Enabling/Disabling Track Modes
Track modes can be enabled and canceled/disabled via Track Mode AT commands.
