Make SPP Connection from PC to Module
In the previous section, the Windows BT stack has allocated COM32 as the outgoing virtual COM port. You
can open COM32 with a terminal program to make an SPP connection to the module which is on COM47; a
transparent UART communication is established between these two COM ports (
Figure 13
).
