BtSerial Pro is a tool which helps you improve the connectivity of your Palm device at the moment you connect, via Bluetooth, to other devices like phones, laptops etc.
BtSerial Pro uses the Bluetooth Serial Port Profile (SPP) to connect to other Bluetooth devices. After discovering the device, they establish a L2CAP, then RFCOMM connection to it. Once this is done, data can be sent and received.
A simple way of fixing issues with your Bluetooth connections.
