BlueGiga WT32 Bluecore SDK?

I’m interested in developing an application for the BlueGiga WT32 module. I see that you can send text commands to the module via UART using their iWRAP protocol, but that the module itself can run applications without the need for another host processor; however it requires that you have the BlueCore SDK. The only place I can find this is the Casira BlueLab which is $3000. Is there a free or much cheaper alternative to getting started with developing to the BlueGiga module?

Thanks
