4. Disconnecting Profiles
A connection to a profile can be released by “ATH<Profile-UUID>”. For A2DP and AVRCP this means
a second way of disconnecting
The response on a disconnect command is usually “NO CARRIER <profileUUID>” if a connection has
existed and S329=0. If no connection has existed and S329=0, no profileUUID is appended.
If all connections are to be released, ATH* may be used. Please see Table 3.17.
