Abstract
Interpretive meta-instructions are used, at a connected vehicle access system (CVAS) device, to implement various RKE protocols by: receiving an RKE-protocol-specific meta-instruction that has been generated by a back-end server; generating an RKE telegram based on the RKE-protocol-specific meta-instruction; and transmitting the RKE telegram to a vehicle. The meta-instruction may include: a device configuration that specifies a set of RF parameters of a CVAS-device transceiver; a template telegram that contains a first set of data fields with data values from the back-end server and that contains a second set of data fields for which data values will be generated and inserted at the CVAS device; and localization-processing commands containing instructions for modifying the second set of data fields of the template telegram.
