7.2.10 Send Operator String to HF (“+COPS…”, #2_4.8)
7.2.11 Change In-band ring tone setting when SLC exists (#4_4.13.4)
7.2.12 Send “ERROR” or “+CME ERROR…” to HF
7.2.13 Subscriber Number Records (“+CNUM…”, #20_4.30)
AT+HFGO”<operator_string>”
Send network operator string to HF by “+COPS:0,0,”<operator_string>” on SLC.
This command shall be used to respond to a “AT+COPS?” request, indicated by the
asynchronous message HFG”OP?”.
AT+HFGB0 / AT+HFGB1
As a prerequisite for this command, the in-band ring flag (0x08) must have been set in
S596 (HFG supported features) at boot time and a service level connection to the HF shall
be established.
Use AT+HFGB0 to indicate to the HF that the HFG will not provide in-band ring tones
subsequently. “+BSIR:0” is sent over the SLC.
Use AT+HFGB1 to indicate to the HF that the HFG will provide in-band ring tones
subsequently. “+BSIR:1” is sent over the SLC.
The BTM module does not create ring tones itself. The actual ringtone signal would have
to be provided by an external circuit and would have to be injected to the analogue audio
input port of the BTM module.
Response: <cr,lf>OK<cr,lf>
Or: <cr,lf>ERROR 68<cr,lf> If no SLC present
Or: <cr,lf>ERROR 69<cr,lf> If in-band ring flag was not set in the HFG supported features
(S596) at boot time.
AT+HFGE<cme_code>
Send “ERROR” to HF if no <cme_code> is given. Required as optional response to
HFG”D>nnn” an HFG”L”.
If the optional <cme_code> is appended and if extended AG error result codes were
enabled by HF (stored internally), the appropriate extended error result code in the form
of +CME ERROR: <cme_code> is sent to HF.
If <cme_code> is appended but extended error codes have not been enabled by HF,
<cme_code> is ignored and only “ERROR” is sent to HF.
AT+HFGS=”<number_string>”,<type>,<service>
This command adds a subscriber number record to the HFG. The subscriber number is the
telephone number of the HFG. It is allowed to have more than one subscriber numbers.
All subscriber numbers available should be stored in the HFG immediately after power up
of the system. As soon as an SLC to a HF device is established, the HF can query the HFG’s
subscriber numbers at any time by sending “AT+CNUM” to the HFG on the SLC. The
subscriber number records existing at that time will be sent to the HF automatically then.
Subscriber number records are stored in volatile memory. Hence they are lost on reset or
power cycle. At maximum 4 subscriber number records are allowed.
