Abstract: A vehicle head unit comprising a memory configured to store an operating system, and one or more processors may be configured to perform various aspects of the techniques. The one or more processors may obtain an indication of one or more vehicle networks, and execute the operating system that presents a single application programming interface that provides function calls by which to configure the one or more vehicle networks within the operating system. The one or more processors may also configure, via the single application programming interface, one or more network interfaces for the one or more vehicle networks in the operating system by which one or more applications, executing in an application space presented by the operating system, interface with the one or more vehicle networks.

Abstract: A host computing device may perform various aspects of the techniques described in this disclosure, and comprises a memory, a processor, and a personal area network (PAN) interface. The memory may store PAN configuration data for each user account of different user accounts, where the PAN configuration data includes a separate layer two host address (L2HA) for use by the PAN interface when supporting a PAN link. The processor may execute an operating system that, responsive to a first user account logging into the operating system: obtain, from the memory, first PAN configuration data of the PAN configuration data specific to the first user account; and initiate programming of the PAN interface to use a first L2HA included in the first PAN configuration data. The PAN interface may establish, using the first L2HA, a first PAN link with a first client computing device associated with the first user account.
