Accessing Digi XBee-PRO®868 RF Modules..

Hello, I'm looking for a library or sample code to access XBee-Pro 868 to 1) Send data 2) Receive data 3) read RSSI values

in API mode. Unfortunatelly, existing XBee library ( rapp's library ) is not designed for this module and most of the functions are not working. many thanks for any help, reha
