Thank you for the answer... If the device is in sleeping mode,the link layer connection will terminate or still it maintain...

It will not terminate immediately, but device will wake up on RTC to maintain the connection. Here You can find better description:

also, read about connection supervision timeout if You are curious.

i am not taling about that sleep time..which is time between two connection events....

i am talking about ,if the entire radio is off for some time (sleep),then upon wake up will it start advertising or will it directly connect to master...my use case is nrf 51 in iot(soft device) scenario...

[Wojtek]

I am not really into iot sdk, cause i am using standard S110/120.

If Your radio is off and not maintaining connection for time longer than supervision time (it is set during connection parameteres negotiation), connection is terminated. I see no difference between not using radio for some time and turning it off and not using it anyway.
