The Audio Gain characteristic is used to expose the gain level of the microphone used for voice capture.  Only a single instance of this characteristic shall exist as part of the RDK Voice Service.<\/p>\n

The characteristic UUID of the Audio Gain shall be set to: 0000EA01-BDF0-407C-AAFF-D09967F31ACD.<\/strong><\/p>\n

Audio Gain Characteristic Value<\/h3>\n

The Audio Gain Characteristic value is an unsigned 8-bit value that contains the current audio gain value. The minimum value is 0 and the maximum value is 64. <\/span>
The Audio Gain characteristic value shall be persistent across connections for bonded devices. The default value for the Audio Gain Characteristic value is vendor specific. Upon connection of non-bonded clients, this characteristic value is set to the default value.<\/p>\n
