nRF8001 sleep and wakeup implementation?

Question

Hi Guys, 
 I'm working with nRF8001 BLE with PIC18F microcontroller, well i have succesfully completed my project but their one last thing i have to add i.e sleep and wakeup i have followed nRF8001 PRoduct specification and even checked source code. Now my doubt is how do i call sleep and wakeup. As is their any specific API their, if not how do i implement one. i have checked they have declared sleep with code 0x04 and wakeup with 0x05 in aci_cmd_opcode_t. 
 NOTE:
I have to call sleep when my microcontroller is about to go in power saving mode. once microcontroller wakeup i have to wakeup nRF8001.

I think you are calling the wrong functions. Why don't you use the ACI interface file . 
You can force the chip to go to standby mode by calling lib_aci_radio_reset(). This will reset the radio (if you are in a connection it will be lost) and the chip will go to standby mode. If you are in a connection you can use lib_aci_disconnect() to end the connection and go to standby mode.
