Table 3.60: Prole connection status
 4. DisconnectingProles
A connection to a prole can be released by “ATH<Prole-UUID>”. For A2DP and AVRCP this means
a second way of disconnecting.
The response on a disconnect command is usually “NO CARRIER <proleUUID>” if a connection has
existed and S329=0. If no connection has existed and S329=0, no proleUUID is appended.
If all connections are to be released, ATH* may be used. Please see Table 3.61.
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 behaviour not dened in
HSP specication.
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 con-
nection has existed: response = “NO CARRIER”
Disconnect all
proles listed in
this table
ATH* Response:
“NO CARRIER <ProleUUID>” for each previously connected prole or
“NO CARRIER” if no existing connection found or HS connected but S332=0
