I'm trying to interface a JY-MCU bluetooth module with a pro mini for the first time and have a decision to make: either connect the RX&TX pins on the pro mini to the bluetooth module, or use the SoftwareSerial library. Since the pro mini doesn't have a USB port, it is programmed through it's RX&TX…

SoftwareSerial library vs. RX&TX pins with JY-MCU bluetooth module?
