S345
S-Register 345 enables automatic alerting on ACL establishment. It contains a bitmask
where bit0 corresponds to outgoing ACL connections and bit1 corresponds to incoming
ACL connections.
If automatic alerting is disabled (S345=0), it can be initiated manually by “AT+HSGC”.
S346
In-band ringing is enabled by S-Register 346 (value =1). If disabled (S346=0), the “RING”
message is send instead to alert the HS.
S347
If the HSG is in “audio connected” state and the HS initiates an audio release by
“AT+CKPD=200” (“Button pressed”), the ACL will be released too if S-Register 347 = 1.
If S347=0, it is up to the user to release the ACL manually by “AT+HSGH” or retain the
ACL by doing nothing.
ATI64
Returns the status of the Audio Gateway (HSP) instance:
0 = not connected
1 = ACL connected
2 = Audio connected
5 = Alerting HS by sending “RING”
6 = Alerting HS by in-band ringing
CONNECT <bd_addr
An ACL connection to headset has been established.

HSG”AU1”
Audio connection (SCO) has been established (= “audio on”).
HSG”AU0”
Audio connection (SCO) has been released (= “audio off”).
HSG”B”
“AT+CKPD=200” (”Button pressed”) was received from HS.
HSG”VGSn”
“AT+VGS=n” with was received from HS (speaker gain setting). The valid range for n is 0..15.
HSG”VGMn”
“AT+VGM=n” with was received from HS (microphone gain setting). The valid range for n is 0..15.
NO CARRIER 1112
ACL connection to local AG-instance has been released. Please note section 6, page 92, too.
