Problems Transmitting Data Through the Serial Port

Solution
If you recently resumed the CK31, wait a few seconds
and try again.
Otherwise, you need to make sure that the device you
selected as the current wireless printer is a printer, is
turned on, and is discoverable.
To learn about the current wireless printer and the
Bluetooth COM port, see "Creating an Application
That Lets You Print Wirelessly" on page 51.
Tap Yes to dismiss the message. Follow the instructions
in "Turning On Bluetooth Power" on page 51 to turn
on the power to the Bluetooth radio.
If you are having problems sending or receiving data through the
integrated serial port on the CK31, check these possible
problems:
• Make sure the CK31 is connected to the PC, host computer,
or RS-232 serial device using the appropriate cable adapter
and null modem cable.
• If the CK31 is in a communications dock, make sure that the
communications dock is connected to the serial device using
the appropriate cable.
• Make sure that ActiveSync is not connecting to the CK31
through the serial port.
• You cannot use the decoded serial adapter or AA2 to connect
to any device other than a decoded scanner. The CK31 auto-
detects the serial adapter or AA2, and the scanner software
makes the COM port unavailable. Instead, use the AA3 to
connect a device like a printer to the CK31. The AA3
requires an external power source.
For more information on using the serial port, see "Configuring
Serial Communications" on page 58.
