User Manual GPS tracker Wireless Communication Device May 07, 2020 1 Introduction 1
The device comes pre‐configured from the factory. It is ready to use. The Flex2‐L appears to a user or a server application as an endpoint device. It can be queried, updated and configured either through a serial connection, an over the air IP connection, or through SMS messaging. The Flex2‐L presents itself over these connections as an enhanced cellular modem with attached functional elements.

3.2 Remote Update The Flex2‐L supports OTA field upgrades of the resident application. An over the air FTP connection is made over an IP connection. A replacement file is then transferred from a server to the Flex2‐L and that file replaces the previous application image. 3.3 Power Modes The Flex2‐L device supports several power modes that are set by AT commands. In full power mode the GPS is active and the cellular subsystem will maintain a persistent cellular connection whenever service is available.
