Thanks for your reply.
So basically, 2 bluebee will be connected automatically when both of them are powered on if the master bluebee not yet connect to other devices previously? So , i dont need to manually connect them right?
Does that mean the API is working and able to display value when 2 bluebee are connected( e.g getRSSI function) and not like previously i connect smartphone to bluebee 4.0 ( which is not working to get RSSI value using API) ?
