This is awesome! I have some serial devices (RS 232) that I've wished I could make wireless. Are there any similar projects to bluetooth serial comms?

Why? My friend needed a way to use his Bluetooth mouse and keyboard on a PC with Bluetooth disabled due to policy restrictions. This tool acts as a bridge, relaying Bluetooth input over USB. It also lets you use Bluetooth peripherals with older devices that only support USB input.

I love HN’s community and often lurk here—I’m hoping this project is useful or at least sparks some interesting discussions. Feedback and contributions are welcome!
If you still want to DIY, an ESP32 (BLE and Wi-Fi capable microcontroller) board, and an RS232 to logic-level breakout board should be all you need. Again, I'm sure if you search, you'll find existing projects doing exactly this.
If it's not actually at RS232 voltage levels and Classic Bluetooth is enough, then something like this will work just fine: https://www.amazon.com/Wireless-Bluetooth-Transceiver-Integr...
