BlueTest Instruction Manual BlueTest is a program that controls the on-chip built-in-self-test (BIST) software for RF testing. This document explains the facilities offered by the BIST. BlueTest does not execute any of these tests. It sends commands to BlueCore01 and/or enables the on-chip BIST, then reports any results. Several tests include entries for Related Test Spec Name. These refer to tests in the Bluetooth Special Interest Group (SIG) Test Specification for RF document, rev. 0.
