Should I use a USB to Bluetooth adapter or an RS-232 serial port to Bluetooth adapter? - bluetooth car adapter
I'm designing and building a Bluetooth radio with a microcontroller MSP430 experimenter board computer. To connect, I just want to know whether it would be easier / simpler software appropriate to a USB or Bluetooth connection with the 9-pin RS-232 on a Bluetooth adapter on your PC? I have almost no experience with USB communication and a little more experience with RS-232.

Bluetooth Car Adapter Should I Use A USB To Bluetooth Adapter Or An RS-232 Serial Port To Bluetooth Adapter?

I do not know your CPU (MSP430), but most of microcontrollers currently have a USB version. (Test Atmel 8051 series).
Most microphones work well with RS232, although the media should lead to fast fashion! Thus, the design for RS232 is working on "Antiques" which is not there a few years, new computer (with a COM port on coming!)
(It's like the development of a landline phone ... while on the platform, you have a 3G phone!)
I suggest that your USB transfer rates faster than serial. Maximum transmission rate of 12 Mbps USB transfer rate is 60bps range. This USB-EB, the best option.
UART library to receive and transmit bytes

A universal asynchronous receiver / transmitter (usually abbreviated UART and pronounced / ju ː ɑrt /) is transforming one kind of "asynchronous receiver / transmitter", a piece of hardware, the data between the serial and parallel forms. UARTs are commonly used in conjunction with the communication standards such as EIA RS-232.
