Hi:

    I  test this hids project, if remove the function bt_conn_auth_cb_register(&auth_cb_display). The iphone will require paired while reconnecting after disconnected. Can you resolve this problem? I don't need the passkey and iphone can reconnected auto after disconnected.

Thanks!

Hi Sam, 

The reason you aren't reconnecting is simply that the app doesn't attempt to reconnect to a disconnected peer. The Central (ie, your app) initiates connections - so it's the app that would have to manage any auto-connect.
