COMMON PROBLEMS and QUESTIONS:
My Bluetooth client can see the Blueport and its serial service, but I can’t connect: This is most likely caused by a security setting on
your client. If a pincode is required, the default is “1234”. Some clients have these settings off by default, others have them on. To check
and disable security:
From your PC desktop, click My Bluetooth Places, go to the Bluetooth Device configuration (or Advanced Configuration)
drop down menu, click on the client applications tab, Select the Bluetooth serial port application name, and click on the properties button, if
“secure connection”, or “authentication”, or “encryption” is checked, un check it.
Changing the clients COM port: Widcomm stack, (and others) allows you to connect to BluePort using a “Virtual COM” port mapper. The
software installs with a default COM port, usually COM3, COM4, or COM5. To change this setting:
From your PC desktop, click My Bluetooth
Places, go to the Bluetooth Device configuration (or Advanced Configuration) drop down menu, click on the client applications tab, Select the
Bluetooth serial port application name, and click on the properties button, then you can change the com port.
Connecting to more than one BluePort from the same client at the same time: Bluetooth allows 7 devices at a time in a piconet.
Widcomm stack allows you to create multiple instances of serial port profile and connect to multiple Blueports at the same time. To do this:
From your PC desktop, click My Bluetooth Places, goto the Bluetooth Device configuration (or Advanced Configuration) drop down menu, click
on the client applications tab, Select the Bluetooth serial port application name, and click on the ADD COM port button, then you can add
another Bluetooth serial port and assign it to another virtual com port (such as COM9).
Connections can be made but during data transfer, no characters flow, or bytes are dropped. Check to see if your flow control signals
are properly connected, and enabled in the serial software you are using. A common mistake is to connect during the boot config timer
window, in this case, all characters will be ignored until a $$$ is seen, and no characters are forwarded to the remote device. If remote
configuration is enabled, the best way to ensure the device is not waiting for configuration is to issue “---“<cr> at the beginning of a connection
and before any user data is sent.
Another common problem is related to hardware flow control,it is not enough to simply disable flow control in your communications software,
the Blueport expects to use hardware flow control, so do disable this on the Blueport you must either remove the CTS flow control jumper, or
short pins 7 and 8 (RTS,CTS) of your cable to permanently enable the flow control.
