I was doing some work on wireless between two boards using the DVP board.
Though, I can't answer directly your problem coz you are using a computer as
your other transceiver. So mine was a little bit easy, but maybe you can get
something from here:
The connection was basically the same with the wired one by Mr. Eacmen. pa7
and use the pd0 of the other transceiver board. Which also means that I am
using one pin for Tx(PA7) and another one for Rx(PD0). (Some of the
initialization code were from Dr. Martin and Dr. Sargent - Arigatou!)
PD0 is the one that's connected with the Tx of the Rs232 in the computer so
maybe you can use it. My configuration is: I only read my data once the
transmitter is directly infront of my other bot, where commands are something
like to put this can on the red trash and this soap to another trash, which
again simplify my usage of RF.
If there is something I can be of further help. Email onegai shimasu.

| Hello, I've been very busy trying to communicate with the Handyboard via a wireless link ( HP Development kit form Linx Technologies). I have run into a slight problem- The kit comes with 2 "development boards" - each contains a transmitter, (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)
