Syntax:
This command allows a DTMF tone to be played on the current speaker. DTMF, gain, and duration can
be set.
Note: This command is only used to play a DTMF tone. To send a DTMF over the GSM network, use
the +VTS command.
<mode>
<dtmf>
<gain> (0-15) Sets tone gain. The values are identical to those of the +WTONE (speaker) command.
<duration> (0-50) Sets the tone duration (unit of 100 ms).
Command syntax: AT+WDTMF=<mode>[,<dtmf>,<gain>,<duration>]
Response syntax: OK or +CME ERROR: <err>
This command switches the product to download mode.
AT+WDWL allows the download process to launch on UART1 only.
Downloading is performed using the 1K-XMODEM protocol.
Important Note: Software damages may occur if power is lost or if a hardware reset occurs during the
downloading phase. This would seriously affect the modem.

0 Stop playing.
1 Play a DTMF tone
Sets the DTMF to play in (mandatory if <mode>=1).
Value must be in {0-9,*,#,A,B,C,D}
Range is 0 to 15 (see array on previous page). By default, the value is 9.
Range 0 to 50. Default 0 (1-> 0,1 s., 50 -> 5 s.)
When this parameter is 0 (default value), the duration is infinite, and the DTMF tone
can be stopped by AT+WDTMF=0.
Possible responses
