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
3-26.

Task AT-Command Comment
Disconnect SPP ATH1101 or AT+SPH or
ATH Single “ATH” retained for backward
compatibility, response “NO CARRIER” or ”NO
CARRIER 1101” depending on S329 and if a SPP
connection has existed previously
Disconnect
A2DP
ATH110D or AT+APH
If A2DP connection released: response = “NO
CARRIER 110D”; If no A2DP connection has
existed: response = “NO CARRIER”
Disconnect
AVRCP
ATH110E or AT+AVH
If AVRCP connection released: response = “NO
CARRIER 110E”; If no AVRCP connection has
existed: response = “NO CARRIER”
Disconnect HSG ATH1112 or AT+HSGH If AG(HSP) connection released: response = “NO
CARRIER 1112”; If no HSP connection has
existed: response = “NO CARRIER”
Disconnect HS ATH1108 or AT+HSH Must be enabled by S332 because it would result
in a behavior not defined in HSP specification.
If HS(HSP) connection released: response = “NO
CARRIER 1108”; If no HSP connection has
existed: response = “NO CARRIER”
Disconnect HFG ATH111F or AT+HFGH If AG(HFP) connection released: response = “NO
CARRIER 111F”; If no HSP connection has existed:
response = “NO CARRIER”
Disconnect HF
ATH111E or AT+HFH
If HF(HFP) connection released: response = “NO
CARRIER 111E”; If no HSP connection has
existed: response = “NO CARRIER”
Disconnect all
profiles listed in
this table
ATH*
Response:
NO CARRIER <ProfileUUID>” for each previously
connected profile or NO CARRIER” if no existing
connection found or HS connected but S332=0
