Q: What parts does the BlueTex software consist
A: A serial port driver and a configuraton tool.
Q: What does the driver do?
A: The Bluetooth module in BlueTex can not handle
7-bits data, which the Mobitex
modem uses. The driver solves this problem for you, so you can open
the serial port "BTX1:" with 7-bits, even parity.
Q: Do I have to use the BlueTex software?
A: No, you do not have to use it. But you have
to open the port with 8-bits, no
parity and mask away the eighth bit (parity) in the received data.
The parity bit in the transmitted data will be ignored. For forward compatibility
we recommend that you insert an even parity bit as the eighth bit.
Q: If the driver is a serial port, why is it named
"BTX1:" instead of "COMx:"?
A: This quote is from MSDN:
"For the file system to recognize file names as devices that
expose the stream interface, the file names must consist of three uppercase
letters, a single digit, and a colon (:)." This means that there can only exist 10 COM ports. And by changing
the prefix to BTX there is less risc that the driver can not be loaded.
Q: Which serial port is used by the BlueTex driver?
A: That is configured with the BlueTex configuraton
tool. Choose the correct
Bluetooth serial port in the drop-down list.
Q: On which PDAs has the software been tested?
A: Compaq iPAQ 3870 with Pocket PC 2002, Fujitsu
Siemens Pocket LOOX 600 with Pocket PC 2002, and HP iPAQ h1900 with Pocket PC 2003. It should work on every PDA running Pocket PC 2002 or Pocket PC 2003.
Q: I have just installed BlueTex and started the
BlueTex configuraton tool, but
I see nothing. The dialog is empty. Why?
A: The driver has not yet been loaded. Load the
driver by either resetting the PDA (it is installed as a built in driver which is loaded after
a reset) or run the command File-> Activate in the BlueTex configuraton tool.
Q: My application must know when the connection
to the BlueTex is broken. Why doesn't the control signals tell me when, for example, the BlueTex
goes out of range?
A: Some Bluetooth stacks does not correctly implement
the control signals. We recommend that you implement a polling scheme if you must know for
certain that the BlueTex is connected. (At least on the platforms whose
Bluetooth stacks are faulty.) To reconnect, the serial port must be closed
