Bluetooth connection: Bluetooth speaker establishes Bluetooth connection with CRY574Pro Bluetooth Dongle.
Bluetooth Speaker test: CRY574Pro drives Bluetooth speakers to produce sound through Bluetooth → The sound is collected by the measurement microphone and transmitted to CRY6151B for test and analysis.
Bluetooth MIC test: CRY6151 drives the mouth simulator to send the sweep signal → Bluetooth speaker MIC collects the echo, and the data is transmitted to CRY574Pro via Bluetooth for analysis by software.
