Position Determination Transport Setting +WPTLM
Description:
This command specifies the transport layer to be used for the position determination session. The transport
layer is carrier specific and may require other PD parameters (IP address, IP port) to also be configured.
Values:
<setting>
0
TCP/IP - Use a TCP/IP based socket for PDE/MS PD data exchanges.
1
DBM - Use data burse messages for PDE/MS PD data exchanges.
Note:
For software versions earlier than v3.0, when a tracking mode is requested (continuous position fixes)
and the TCP/IP transport layer is used, position fixes will not be delivered until the data call ends. Then, only
the last 10 position fixes will be presented.

Set Position Determination IP Address +WPDIP
Description:
This command is used to set the IP address for the position determination session. A valid IP address is
required if the TCP/IP transport layer is used.
Values:
<ip_address>
Specified in standard IP address format xxx
.
xxx
.
xxx
.
xxx where xxx is 000 to 255. This is a carrier specific
value.

Command syntax:
AT+WPDIP=<ip_address>
Command
Possible responses
AT+WPDIP?
Note: Query current PD IP address.
+WPDIP:192.168.135.124
OK
AT+WPDIP=192.168.135.124
Note: Set PD IP address.
OK
Note: New PD IP address set.
Set Position Determination Port ID +WPDPT
Description:
This command is used to set the port ID value for the position determination session. A valid port ID value is
required if the TCP/IP transport layer is used.
Values:
<port_id>
Numeric value in the range 0 to 65535. Value is carrier specific.
Syntax :
Command syntax:
AT+WPDIP=<port_id>
Command
Possible responses
AT+WPDPT?
Note: Query current PD port id value.
+WPDPT: 4911
OK
AT+WPDPT=4911
Note: Set PD port id value.
OK
Note: New PD port id value set.
