Q: When entering the command ATF? it returns an error when trying to search for
Bluetooth devices in range.
A: In order to have the UCBT232B/EXA display Bluetooth devices in range it must be in
Master mode, and must not be in auto-connect mode.
Q: How do I configure the UCBT232B/EXA for 7 data bits, 1 stop bit and even parity?
A: The adapter itself cannot be set to 7 data bits however it can still transmit 7 data bits
through the air, so if you configure your computer/software and the device you remotely
connect to the adapter to 7 data bits then the adapter will automatically transmit this
configuration.
Regardless of which number of data bits, parity and stop bits you need, you should
always set the UCBT232B/EXA to 8 data bits, no parity and one stop bit. This is because
the UCBT232B/EXA is simply a conduit of bits, it only cares of the number of bits and
not of meaning of those.
Q: How is DTR/DSR signals (pins 4 & 6) handled by the UCBT232B/EXA?
A: The DTR signal is rarely used in most serial devices and even if it is used it is often
not actually required by the application. This is why the UCBT232B/EXA has looped
back the DTR / DSR signal, pin 4 looped to pin 6. By doing this, if the device asserts
DTR indicating it will read an asserting DSR. For devices that require an asserting DSR
but are not asserting DTR the DSR signal (pin 6) can be shorted to RTS (pin 7).
