Up to
BlueCore2-External has been designed to reduce
the number of external RF components required,
which ensures module production costs are
minimised.
The device incorporates auto calibration and
built-in self-test routines to simplify development,
type approval and production test. All hardware
and device firmware is fully compliant with the
Bluetooth specification v1.1.
