I would suggest you to do a full erase of the chip before testing. The peer manager support pairing with multiple devices until a maximum number (should be 8 AFAIK). It could be the case that you already paired with max number of devices. You can find when we initialize peer manager , there a clear bonding button that's checked to erase bond information if needed.

You can delete a particular bond information of a central. You can have a look here.

Thanks Hung Bui for your support for the above answer. I am able to solve my one problem of repairing with the same device but unable to solve the other problem (pairing with other devices) i am not getting how to delete peer bond information of the device or to add multiple devices and storing their information im memory

Hi Deepash,

If you have a look at line 225 in your main.c you can find in PM_EVT_CONN_SEC_CONFIG_REQ event you send conn_sec_config with allow_repairing = false. This mean you tell the device not to let the phone to re-pair to your device. So either you change this option, or you erase bond information on the device so you can have a new bonding to the phone.

This is the default behaviour because it avoid attacker to spoof that the phone losses bond information and can replace the original bond with a new bond.
