The Palm should be configured with a connection profile set to 'Connect to PC via Bluetooth', and the device should be set to your computer. Under details, you will need to set the spped to 115,200 bps, and the Flow Ctl to automatic.

You will also need to create a new network profile, set to use the connection you just created. No username or password is necessary. Under details, the idle timeout should be set to never, and under advanced, specify an IP address of 10.0.1.201. You may use whatever DNS servers you like, reccomended are 4.2.2.1 and 4.2.2.2.

Once this is configured you should be able to connect."
