1 Introduction The WCM is a self-contained vehicle tracking device that combines GPS location with LTE CAT-M cellular connectivity. It is primarily a location reporting device that responds to requests (user, server) and events (timers, geo-fences). Data reports consist of a single record that contains all location data and system status. The device comes pre-configured from the factory. It is ready to use. The WCM appears to a user or a server application as an endpoint device.

are outside the scope of this document. GPIO One dedicated input, two dedicated outputs, and one general purpose IO are presented to the external environment on the main connector. They are capable of providing system interrupts to generate a report or drive logic levels to external devices. These lines are 3.3V logic level and are 30V tolerant. These pins default to input and are pulled down representing 0 when disconnected. They should be asserted to a known value if used.
and consequently covers a scale from 0 to 30 Volts. Timers Timers resident on the baseband chip generate periodic interrupts for power down wakeup, watchdog support, periodic report generation and other timer related functions. Watchdog The Quectel BG96 Module provides internal software Watchdog. Also the WCM includes an MCU that acts as a failsafe external watchdog. The MCU power cycles the system, if no activity is detected for 1 hour.

Ignition Trip start and stop Any hardware or software reset will return the device to full power mode. 3.4 AT Commands Extended AT commands are specific to the WCM device. They are closely based on commands that are as similar as possible industry common devices and are essentially subsets of standard WCM commands. Native AT commands supported by the Quectel BG96 modules are also available via the serial and USB interfaces. 3.
3.7.1 Context Preservation When a self-initiated reset is performed due to Network Watchdog or by the Reset command (modes 0,1), the context of the system is being preserved and is restored after the reset. The context includes all the periodic timers, the report queue, the odometer, etc. This allows to reset the unit as a troubleshooting or preventive measure without losing reports that are already in the queue or are pending on running timers.
