BlueCore4-External has been designed to reduce the
number of external components required which
ensures production costs are minimised. The device
incorporates auto-calibration and built in self test
(BIST) routines to simplify development, type
approval and production test.
All hardware and device firmware is fully compliant
with the Bluetooth v2.0 + EDR specification (all
mandatory and optional features). To improve the
performance of both Bluetooth and 802.11b/g
co-located systems a wide range of co-existence
features are available including two types of
hardware signalling: basic activity signalling and Intel
WCS activity and channel signalling.
