As soon as Connection is established (GAP Peripheral device receives CONNECT_REQ packet) advertising is over. If device can and wants to advertise even it runs GAP Peripheral connection link it would need to restart it explicitly. If you experience some problems after pairing (= if your devices are disconnecting unexpectedly) or anything else you will need to give us more details. And also never reply to 3-year-old question, start new one (unless you find in search answer in one of 20 thousand Q&S - which is actually very likely;)

Is it possible to stop adverstising and keep the connection established after pairing?

Rx mode need power also, So, peripheral can not be in Rx mode long time, So, It's impossible.

No, this is not possible.

According to the 4.1 Core Spec, the Create Connection command "is used to create a Link Layer connection to a connectable advertiser." The connection creation implies going into the scanning state to look for advertisers with a specified (resolvable) address, and sending a CONNECT_REQ packet at an exact moment after an advertisement packet is seen on a specific channel.

By default, the S110 is in the non-connectable state until advertising is started. It can then either lead to a connection state or time out, like seen in the API documentation at [1] and [2].
