Project Overview
Xicato develops intelligent LED lighting systems used in museums, galleries, theaters, and other high-impact architectural spaces. To simplify lighting management, the company introduced XIMtroller, an iOS application that allows designers and facility managers to configure lighting scenes, adjust brightness, and schedule settings directly from mobile devices. Closeloop improved the platform’s Bluetooth communication layer, addressing instability in Apple’s CoreBluetooth framework while implementing secure device communication using encryption. The resulting solution provides a stable, secure, and intuitive lighting control experience for managing multiple lighting fixtures in professional environments.
Business Challenges
- Establishing stable Bluetooth connectivity between iOS devices and XIM lighting modules.
- Frequent connection drops caused by CoreBluetooth framework instability.
- Provisioning and commissioning multiple lighting fixtures simultaneously.
- Ensuring secure communication for lighting control across public and private networks.
- Maintaining reliable device interaction in complex lighting environments.
Solution
- Improved Bluetooth communication protocol between iOS devices and XIM lighting modules.
- Resolved CoreBluetooth connectivity issues to stabilize device communication.
- Enabled reliable provisioning and commissioning of multiple lighting fixtures.
- Implemented public-private key encryption for secure command transmission.
- Enhanced system reliability for professional lighting environments.
Approach
- Analyzed Bluetooth communication patterns and connection failures.
- Refined device communication protocols for stable provisioning.
- Implemented encryption mechanisms for secure command exchange.
- Optimized device interaction for commissioning multiple fixtures.
- Continuously tested reliability in real lighting deployment scenarios.
