How It Works
The project involves two laptops, each connected to a BleuIO USB dongle. For simplicity, we designate one laptop as User 1 (Central role) and the other as User 2 (Peripheral role). Here’s a high-level breakdown of the workflow:

Setup:
Each laptop runs a script to initialize its BleuIO dongle. User 1 starts in a dual role and acts as the central device. User 2 also sets its dongle in a dual role but begins advertising itself.
Connection:
Once User 2 starts advertising, it displays its MAC address. User 1 uses this MAC address to connect to User 2.
Messaging:
After establishing a connection, the users can send and receive messages in real time. The communication is direct and local, with no reliance on external servers.
