Getting Request from FritzBox TR-064 API fails

Question

I'm trying since days to get the info of via Wifi connected hosts from my FritzRepeater which is offering an SOAP API for that. I'm using curl... everything is working fine until I have to use arguments/parameters. It seems like I'm missing something about the correct body format.

For example - working request NOT using arguments:
location="/upnp/control/deviceinfo"
uri="urn:dslforum-org:service:DeviceInfo:1"
action="GetInfo"
par=""
param=""

curl -k -m 5 --anyauth -u "$FRITZUSER:$FRITZPW" http://$IP:49000$location \
        -H 'Content-Type: text/xml; charset="utf-8"' \
        -H "SoapAction:$uri#$action" \
        -d "<?xml version='1.0' encoding='utf-8'?>
                        <s:Envelope s:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/' xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'>
                                <s:Body>
                                        <u:$action xmlns:u='$uri'>
                                                $param
                                        </u:$action>
                                </s:Body>
                        </s:Envelope>"

RESPONSE:

<?xml version="1.0"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

And the same with parameters/args:

location="/upnp/control/wlanconfig1"
uri="urn:dslforum-org:service:WLANConfiguration:1"
action="GetGenericAssociatedDeviceInfo"
par="NewAssociatedDeviceIPAddress"
param="<s:$par></s:$par>"

curl -k -m 5 --anyauth -u "$FRITZUSER:$FRITZPW" http://$IP:49000$location \
        -H 'Content-Type: text/xml; charset="utf-8"' \
        -H "SoapAction:$uri#$action" \
        -d "<?xml version='1.0' encoding='utf-8'?>
                        <s:Envelope s:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/' xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'>
                                <s:Body>
                                        <u:$action xmlns:u='$uri'>
                                                $param
                                        </u:$action>
                                </s:Body>
                        </s:Envelope>"

RESPONSE:

<?xml version="1.0"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<s:Body>

Anybody have an idea of what I am missing?

Answer 1

The manual wlanconfigSCPD.pdf lists the input parameter NewAssociatedDeviceIndex instead of NewAssociatedDeviceIPAddress. The parameter NewAssociatedDeviceIndex requires a numeric value from 0 to result of GetTotalAssociations() minus 1.
