1. A method of preserving battery power for an asset tracking device, the method comprising:
detecting, at the asset tracking device attached to a trailer, using a communication system, a first trigger identifying a third-party electronic logging device (ELD) attached to a truck in close proximity, and in response, generating an association between the trailer and the truck, wherein the ELD has a first mobile network connection and a location tracking capability;
responsive to detecting the first trigger, entering, at the asset tracking device, a sleep mode in which the asset tracking device does not periodically determine its location using a global navigation satellite system (GNSS) chip and does not periodically power a cellular transceiver; and
detecting, at the asset tracking device, a second trigger and, in response, exiting the sleep mode and entering a normal operating mode in which the asset tracking device is configured to periodically determine its location using the GNSS chip, to periodically power the cellular transceiver to seek a connection to a mobile network, and to provide location data from the GNSS chip to a central server over the connection to the mobile network.
