AI Technical Summary

Technical Problem

In industrial applications where electronic devices, such as hazardous area light fixtures, operate offline without cloud or external network connectivity, there is a challenge in managing updates and limiting simultaneous access by multiple users to prevent conflicts.

Method used

The method involves each electronic device in the mesh network maintaining a proxy device count and using lists to track active updates, allowing only a limited number of mobile devices to connect and update features, and synchronizing this information across the network.

Benefits of technology

This approach effectively limits the number of mobile devices accessing and updating features on offline mesh network devices, preventing conflicts and ensuring data synchronization, even in the absence of external connectivity.

Abstract

A method to manage updates to electronic devices of a mesh network in an offline environment is provided. Each electronic device of the mesh network includes a memory, the memory including a proxy device count indicating an active number of devices in the mesh network acting as a proxy device connected to a mobile device. The method includes receiving, by a device of the mesh network, a connection request to the device by the mobile device, and checking, by the device, the proxy device count. Responsive to a determination that the proxy device count is less than a maximum number of proxy devices, the device: connects to the mobile device, increments the proxy device count by one, and communicates a first message to other devices of the mesh network that the device acts as a proxy device to synchronize the proxy device count across the mesh network.
