Note
In 2015 the Bluetooth Test Specification was amended to relax the drift rate test
limit for the drift measured between the preamble and the first ten bit section of the
payload. MT8852B firmware version 4.20.007 and later incorporate this change
and describe this measurement as the Initial Drift Rate.
