pheripheral advertising.

[Amit Varshney]

I'm using s110 pheripheral mode in my application. I want it to be in sleep mode and do not advertise untill a central want to connect it. Is it possible, when a central start scan my pheripheral device read it and start advertising without any gpio interrupt.

There is no way to detect any scanning if there is no advertisment. That's how BLE is designed by specification, any active scanning or conenction request packet can only come in very narrow window (150us) after some ADV_xxx packet.
