COMMON PROBLEMS and QUESTIONS:
My Bluetooth client can see the RN-24 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, 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 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
RN-24 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, 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 properties button, then you can change the com port.
Connecting to more than one RN-24 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 RN-24s 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, a safe
way to be sure to be in data mode is to issue “---“<cr> at the beginning of a connection
and before any user data is sent.
