Building a Remote BLE Interface: Access BLE devices from Any Location - BleuIO - Create Bluetooth Low Energy application

Remote access to Bluetooth Low Energy (BLE) devices opens up new possibilities in IoT , distributed applications, and various remote monitoring and management scenarios.

Remote access is invaluable for developers, researchers, and organizations that need to control or monitor BLE devices located in remote or hard-to-reach locations.

We will explain how to set up both local and cloud servers, and how to establish a secure connection between them.

We’ll be using LocalTunnel as it’s free and easy to set up, but feel free to explore other solutions if they better meet your needs.

In your local_serial_server.js, specify the correct serial port path for your BLE dongle (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux ) In this setup, Cloud device will act as the cloud server that connects to local device’s local server.

This URL will allow cloud device to access the local server running on port 4000of Local device.

This tutorial demonstrates the potential of combining Node.js, BLE technology, and tunneling services for remote BLE access.

With this setup, Cloud device can be anywhere in the world, allowing you to control and receive data from the BLE dongle on Local device (in Stockholm ) remotely.
