The integration of Bluetooth Low Energy (BLE) into lighting solutions had opened up new possibilities for remote management and diagnostics. Our recent project involved the development of a lighting solution with BLE-enabled lights, integrated with the power of the Sensor Vision platform. This blog post explores the key aspects of the project, focusing on the implementation of a BLE gateway using ESP32 and Sensor Vision’s capabilities.
The primary goal of the project was to eliminate the need for physical presence when diagnosing and debugging deployed lighting devices. To achieve this we developed a BLE gateway. This gateway would connect to the cloud backend through GSM or WiFi, enabling remote diagnostics and troubleshooting.
The ESP32 served as the key component of our BLE gateway. The gateway’s operations were designed to seamlessly connect, communicate, and retrieve data from BLE-enabled lights. Here’s a breakdown of its key functionalities:
- Cloud Connectivity:
The BLE gateway established a connection to the cloud backend using either GSM or WiFi, ensuring reliable internet connectivity for remote operations.
- BLE Device Scanning:
The gateway scanned the local environment for BLE-enabled devices, identifying and cataloguing the deployed lights.
- Cloud Commands Processing:
Commands received from the Sensor Vision cloud platform were processed by the gateway, converting them into BLE commands suitable for communication with the deployed devices.
- BLE Command Transmission:
The gateway sent converted BLE commands to the respective BLE devices, allowing for seamless remote control and configuration adjustments.
- Response Handling:
As BLE devices executed the received commands, the gateway captured responses, ensuring two-way communication between the cloud backend and the deployed devices.
- Publishing Parameter Value:
The gateway published parameter values received from the BLE devices to the Sensor Vision cloud platform, creating a comprehensive feedback loop for real-time monitoring and analytics.
- Sensor Vision Integration:
The project leveraged the Sensor Vision platform, to enhance the remote diagnostics capabilities. MQTT (Message Queuing Telemetry Transport) and BLE were the key communication protocols ensuring seamless integration between the gateway and the Sensor Vision cloud.
The successful implementation of the BLE gateway, ESP32, and Sensor Vision platform showcased the transformative potential of smart technology in the realm of lighting solutions. By enabling remote diagnostics and debugging, the project not only reduced the dependency on physical technicians but also paved the way for future innovations in IoT-driven applications.
