I see the Bluetooth incoming and outgoing COM port, but I fail to open them.
Answer: This may due to that the COM port is occupied by other application. Please close the
application that occupied the Bluetooth COM port. It may also due to wrong setting of Baud
rate, most of the PC can support Bluettoth Baud rate 115200, please try to this baud rate. If
your PC can support Bluetooth Baud rate 921600, of course you can use it to transfer the
image faster.
