Connecting the Unconnectable – A VB.NET Bluetooth Journey Prologue – The Forum Post Posted by CodeNewbie_42 on VBForums, 3:14 AM: "Help! I need to send a simple string from my VB.NET Windows app to a Bluetooth-enabled Arduino. I’ve tried SerialPort, 32feet.NET, even PowerShell – nothing works. The device pairs, but no data flows. What am I missing?" Chapter 1 – The Reply from a Guru User: SerialPortSavior (MVP, 12,847 posts) Replied: "Ah, young coder. Bluetooth on Windows with VB.NET is not magic – it’s emulated serial over RFCOMM . Here’s the path:" Step 1: Install 32feet.NET (the de facto library) May your posts remain forever unarchived
