A method and system for dynamically broadcasting device data using a standard Bluetooth Low Energy (BLE) advertisement packet is provided. Specifically, the Bluetooth advertisement packet can be Bluetooth 4.0 compatible that has a maximum payload size of 31 bytes excluding MAC address. The Bluetooth advertisement packet can be modified to include one or more data corresponding to one or more parameters gathered or detected by one or more sensors. The parameters can include acceleration, velocity, temperature, pressure, and the like. A BLE device employing the data schemes disclosed herein can further be configured to broadcast multiple advertisement packets each containing different data corresponding to different parameters. Thus, expending the payload capacity of advertisement packets without having to initiate pairing between a remote device and the BLE device and maintains backward compatibility without requiring the remote device to be advertising extensions (Bluetooth 5.0) compatible.

Aspects of the invention provide apparatuses, systems, and computer readable media for protecting a programmable logic controller (PLC)and plant networkagainst unauthorized access and for providing robust intended communication. A communication moduleprovides only intended communication and blocks all unintended communication between the plant network and a control network/office networkwithout using external infrastructure network devices. The communication module includes an Ethernet switchand ports that electrically couple the CPU module, a plant network, and control/office network and controls communication to the PLC and the plant network from the control/office network by forwarding packets based on configuration informationand, where the packets are received through the ports. The communication module passes packets only when the associated source address and destination address are in accordance with the configuration information. The communication module may further pass packets based on packet traffic limits.
