6.2.7 Enable Automatic Alerting on SLC Establishment
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”.
6.2.8 Enable In-Band Ringing
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.
6.2.9 Enable Automatic SLC Release
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.
