Why cannot?
You can connect the SKKCA to computer through USB cable and it will become a COM port, let's say COM 10. Now connect another SKKCA to another USB port, it will become another COM Port, let's say COM 20. Open 2 HyperTerminal, or another terminal program such as Arduino IDE serial monitor, X-CTU also can. Select the correct baudrate and walah.... you are ready to communicate with the SKKCA.
Your microcontroller communicate with SKKCA using UART too, is the same as COM port on computer. So your Hyperterminal connect to COM10 is actually a microcontroller, another Hypterminal that connect to COM 20 is another microcontroller. Try to do the process to pair up this bluetooth first, only your proceed to microcontroller.
If you have never do this, I am sure you are just connecting 2 SKKCA and hope they connect by themselves, right? You can wait until next ten year, it will never happen
