 Harley, Dana, what is this? This is the desombification of the EasyLink Blue Fruit. Originally, I did this with the CSR chipset. Now we're trying to rebuild this board with an ESP32, which has Bluetooth classic support. I have it wired up here to an Arduino Uno. The DTR line is connected to a capacitor. You can see data being transmitted. Blue means it's connected to Bluetooth. And I just uploaded a NeoPixel sketch. So what's interesting about this code is it does the baud rate selection correctly. So whatever baud rate you open up, the COM port over here on the computer at, it does that. And also it passes through the DTR, DSR, RTS, and CTS lines. So it's actually kind of like a transparent serial port over a Bluetooth classic. So far it's working pretty well. So I'm excited to get this design wrapped up and into the Adafruit shop.
