Re-connecting Using My Contacts
Turn the Helper and the Boss robots on.
Get the Boss to go to the Bluetooth menu and select My Contacts. If you use My Contacts the boss remembers the Passkey automatically. Connect to the Helper and assign the same connection number!
It will wait for a while trying to find the Helper. Be sure it is on and close by.
Once it is done you'll see the connection icon has changed from "<" to "<>" (see the picture below). You're connected!
