5. Legacy Response Format (BISM2)
Some BISM2 responses have been slightly changed on BTM modules in order to provide enhanced
functionality. If required, a BISM2 compatible response format can be enabled by S Register 329.
Table 3.19 shows the implications of enabled/disabled legacy response format.

Legacy response format
enabled (S329=1)
Response = “NO CARRIER”
Response = “NO CARRIER”
Response = “NO CARRIER”
Response = “NO CARRIER”
Response = “NO CARRIER”
Table 3.17: Profile release commands
Single “ATH” retained for backward compatibility, response “NO
CARRIER” or ”NO CARRIER 1101” depending on S329 and if a SPP
connection has existed previously
If A2DP connection released: response = “NO CARRIER 110D”;
If no A2DP connection has existed: response = “NO CARRIER”
If AVRCP connection released: response = “NO CARRIER 110E”;
If no AVRCP connection has existed: response = “NO CARRIER”
If AG(HSP) connection released: response = “NO CARRIER 1112”;
If no HSP connection has existed: response = “NO CARRIER”
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”
If AG(HFP) connection released: response = “NO CARRIER 111F”;
If no HSP connection has existed: response = “NO CARRIER”
If HF(HFP) connection released: response = “NO CARRIER 111E”;
If no HSP connection has existed: response = “NO CARRIER”
Response:
“NO CARRIER <ProfileUUID>” for each previously connected profile or
“NO CARRIER” if no existing connection found or HS connected but S332=0

0 = disabled (default)
1 = enabled
Legacy response format disabled (S329=0)
If SPP was connected, response =
“NO CARRIER 1101”
If SPP was not connected, response =
“NO CARRIER”
If A2DP was connected, response =
“NO CARRIER 110D”
If A2DP was not connected, response =
“NO CARRIER”
If AVRCP was connected, response =
“NO CARRIER 110E”
If AVRCP was not connected, response =
“NO CARRIER”
If HS instance was connected, response =
“NO CARRIER 110E”
If HS instance was not connected, response =
“NO CARRIER”
If HSG instance was connected, response =
“NO CARRIER 1112”
If HSG instance was not connected, response
= “NO CARRIER”
