Chapter 14 – Specific AT Commands

Play DTMF Tone +WDTMF

Description: This specific command allows a DTMF tone to be played on the current speaker. DTMF, volume and duration can be set. This command is only used to play a DTMF tone. To send a DTMF over the CDMA network, use the +VTS command.

Values:

<mode>

 

 

0: Stop playing.

 

 

1: Play a DTMF tone

 

 

<dtmf>: This parameter sets the DTMF to play in {0-9,*,#,A,B,C,D} (mandatory if

 

<mode>=1)

 

 

<volume> (0-3):This parameter sets tone gain. The values are identical to those of the

 

+WTONE (speaker) command (mandatory if <mode>=1).

 

<duration> (0-50):This parameter sets the tone duration (unit of 100 ms). When this

 

parameter is 0 (default value), the duration is infinite, and the DTMF tone can be stopped by

 

AT+WDTMF=0.

Hardware Version +WHWV

Description: This command displays the MSM version along with hardware version number.

 

MSM version display format: Major.Minor; e.g. 240.16

 

Major:

240 denotes MSM

 

 

Minor:

1 denotes 5105; 06 denotes typeout version 6;

 

 

8 denotes 6050; 02 denotes typeout version 2;

 

The three-digit production hardware version is written to the modem during manufacturing.

 

First digit represents PCB version (ex: 5. as in V5). The second and third digits represent

 

last two digits of part-list number (ex. 04). In this case the hardware version number will be

 

504.

 

 

 

If the hardware version has not been written by manufacturing second filed of this command

 

will be 0.

Possible Responses

 

AT+WHWV

 

+WHWV: 240.16,504

 

Note: Request MSM Version

OK

 

 

 

Note: MSM version is 240.16 (5105 chipset), PCB version is 5 and

 

 

 

parts-list used during manufacture is 04.

 

AT+WHWV

 

+WHWV: 240.82,0

 

Note: Request MSM Version

OK

 

 

 

Note: MSM version is 240.82 (6050 chipset), hardware version is 0
