Not sure what you mean by 'converter'.  Do you mean the MAX232?  It all depends
on your BT module,  whether it accepts TTL level or, (e.g., if a more integrated
module) RS232 level signals.  You certainly need one for connecting to the PC,
though.

Would a serial interface converter be needed for such a project? I'm 
curious..^^
Could do with bit more of info on this. Thanks alot.

Trying to kill two birds with one stone, aren't we?

Most, if not all, Bluetooth (BT) modules I've seen work like modems using an
AT command set.  So, forget about the BT module, and write your SCI code so
it can talk to a PC (the hardware requirements I leave up to you, e.g.,
level transalation, null-modem cables, etc.).

Then, make the 68HC11 send the appropriate AT commands thru the SCI to the
PC where (by use of a terminal like HyperTerm on Win), you manually type
back the expected responses.  (If you have some of the more advanced
terminal programs, you could even prepare a script that behaves like a BT
module.)  Once you get this working, add your Bluetooth module to the SCI
and it should work (as far as communicating to the module is concerned).

Beyond this point, if you can't make the two BT modules work, it's a
different (non-SCI) issue (e.g., hardware, distance, settings, protocols,
etc.)

Good luck.

Hi, I'm currently working on a project which requires me to use the 
serial communications interface on the M68Hc11 board to interface it 
with a Bluetooth module (Promi-SD 202). I need to test it by sending 
out a data using the module and verify if it is received by another 
set of Bluetooth device.
After doing several references, I came up with a simple program to 
send 8 bit data to the SCI. But the problem is, i'm still unable to 
get the data sent through the promi sd bluetooth module.

Any ideas on how to interface the M68HC11 SCI with the Bluetooth 
module so that i can get it to send the data out?

Thanks sincerely, claire.
