Q&A.
1.
FS28 has been built up a connection to PC and the Blue LED is turned on, However,
FS28 cannot send image to PC.
Answer
: Please check whether you have selected the right Bluetooth COM port for the PC
demo program (
FS28BluetoothMasterModeDemo.exe
.). For FS28 initiate the connection, you
should choose the Bluetooth incoming port. For PC initiates the connection, you should choose
the Bluetooth outgoing port. Please check you Bluetooh incoming port and outgoing port by
following the procedure on Page 13. After you have chosen the right COM port, please open it
before you start scanning your finger. Otherwise, the FS28 will pop out the message “Pc/Phone
Rsp timeout”, that means PC is timeout to receive the image as the COM port has not been
opened.
2.
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.
3.
My PC cannot open the FS28BluetoothMasterModeDemo.exe /
FS28BluetoothSlaveModeDemo.exe.
Answer
: Have you installed Microsoft .Net Framework 4.0 Client Profile? It is need to be
installed before you run the demo program. If Microsoft .Net Framework is not installed,
please download and install it from

FS28BluetoothMasterModeDemo.exe is hanged when receiving WSQ image but it can
receive RAW image successfully.

FS28BluetoothMasterModeDemo.exe
.
ftrWSQ.dll
is used to show the WSQ image after it is
received from FS28.

I forget the Bluetooth PIN code that I set before.
Answer

can also just select 4. Set Factory Default, it will reset the BT PIN code to “0000”.

I have falsely enabled AVR Firmware upgrade; I want to quit the upgrade process and go
back to normal operation.
Answer
: If you have not started downloading AVR firmware from PC to FS28, you can quit by
holding SELECT button and press REST button. Then FS28 will leave Firmware upgrade
menu and reboot to normal operation. If the AVR firmware has been started downloading to
FS28, you should not quit this process and have to wait for upgrade process complete.
