this is possible, but you need at scatternet capable Bluetooth chip (for
example a CSR BlueCore with HCI 16.4 firmware or newer). What you really
need to make sure is that the roles are switched correctly. Remember
that the device that initiates a connection is the master of a piconet
in the first place.
