Configuring a Sample Pattern ID
Overview
The following example shows how to configure Pattern ID 0x17 to receive a three-second, 400 Hz tone. To perform this task, the host sends three API messages as follows:
1. Tone Configure message to replace the default tone (Tone ID 0x0F, 425 Hz) with the new, 400 Hz tone.
2. CPA Pattern Configure message - create the new Pattern ID 0x17.
3. CPA Class Configure message - add Pattern 0x17 to class 0x00.
