Currently I don't have a Sniffer Trace .Once i got that i will post.Thanks for your quick reply.

I was actually wondering if you are using a development kit or some other pcb?

The 32KHz source is used for protocol timing. Using the internal rc would make sure there are no issues with the timing. If you have issues with your 32KHz source you might not be able to connect as the listening window on the slave would be misplaced, thus loosing packets from the master (the first packet after the connection request is critical for the link to be established). It could also lead to problems keeping a connection and you might suffer from packet loss.

Do you have a sniffer trace that shows the on air packets?

I am not using whitelist.My hardware is nrf51822QFAAHO.How the performance of Rc source will affect connection and disconnection event?????

As far as I can see the connection is not established. Which means the connection request was not received or it was ignored by the peripheral. Are you sure that you ate not using a whitelist?

What hardware are you running this on? Are you sure your 32kHz rc source is ok? Consider testing the internal RC to see if this works better.
