MotionFit bluetooth sleep

Hello,

I want to put the bluetooth module on MotionFit SDK board to sleep. Looking at the schematic, the module is BR-C46AR and looking around it appears that the firmware on these modules support AT commands but I have not been able to find a document that describes specific commands supported by this module. Does anyone here have access to this information or any suggestion as to how can I put the module to sleep from MSP430?

Thanks
