Bluesmirf com ports?

Hello,

I bought a bluesmirf module to remotely control an ATMEGA32 based robot (Arexx RP6).

When the connection is set it’s created a virtual COM (just one, inbound) and i can read what the ATMEGA loaded C program is is transmitting but i can’t send any command back to to it… it seems to work in one way only… I would exclude the hardware connection that seems to be ok (rx tx inverted and so on).

Should the bluetooh create one or two virtual comms to communicate with a device in both ways ?

Any help or explaination on how the bluesmirf communication should be would be apreciated.

Thanks - Francesco
