 Could you attach a traffic capture of your issue

 We have attached the capture

 The OUI and the serial number are empty in your inform message. and this is the cause of the fault you got from the ACS. you have to put them in the easycwmp config or you should update your data model scripts.

 Thanks, I've checked the data model source code and corrected. Now in the tcpdump both the value were passed with data. But at the end we received the same error. You can check on the new capture uploaded. Thanks

 it's not empty for params, but it's still empty for DeviceId

<DeviceId>
     <Manufacturer>GL-CONNECT</Manufacturer>
     <OUI></OUI>
     <ProductClass>gl-inet</ProductClass>
     <SerialNumber></SerialNumber>
</DeviceId>

You have to update also the function "common_get_inform_deviceid()" in the common script

 Thankd for your support. I changed also that part, and now the last message received from the server is different.

rpc_inform(228): parse Inform xml message from ACS failed

Still parse problem, but different from before.
You can also check everything in the new capture file : capture4.pcap

 I m not sure if it's a bug or an interoperability problem. I do not have the time now to investigate this problem. I will check it when I will treat the next release. as a quik solution you can avoid the check of the received inform response. Just add return 0 at the beginning of the function:

int xml_parse_inform_response_message(char *msg_in)

This should fix your problem but not in a proper way

 After applied that fix you suggested, we are able to make a step forward on the xml process of the tr-069 transaction.
Now we received this error :
rpc_get_rpc_methods(188): parse GetRPCMethods xml message from ACS failed
But it is always related to the SOAPAction that we received from the ACS server.
Comparing the capture between the same CPE and different ACS server, we saw this difference :
1) receiveing from ACS SOAPAction: is working
2) receiveing from ACS SOAPAction: "" is not working

 This issue will be treated in the next release (inchea allah)

But I have a quick solution to fix this las problem. Like the inform, you can avoid the GgetRpcMethodResponse check by adding a return 0 at the beginning of the function:

int xml_parse_get_rpc_methods_response_message(char *msg_in)

 I know that you do not have time for investigation. After applying both the two fixes suggested, we made a step over.

We are able to receive these data from the server :

<env:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" [^] xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" [^] xmlns:cwmp="urn:dslforum-org:cwmp-1-2" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" [^] xmlns:xsd="http://www.w3.org/2001/XMLSchema" [^] xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> [^]
<env:Header>
<cwmp:ID env:mustUnderstand="1">6357545</cwmp:ID>
</env:Header>
<env:Body>
<cwmp:SetParameterValues xmlns:cwmp="urn:dslforum-org:cwmp-1-2">
<ParameterList SOAP-ENC:arrayType="cwmp:ParameterValueStruct[4]" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> [^]
<ParameterValueStruct>
<Name>InternetGatewayDevice.ManagementServer.PeriodicInformEnable</Name>
<Value xsi:type="xsd:boolean">1</Value>
</ParameterValueStruct>
<ParameterValueStruct>
<Name>InternetGatewayDevice.ManagementServer.PeriodicInformInterval</Name>
<Value xsi:type="xsd:unsignedInt">300</Value>
</ParameterValueStruct>
<ParameterValueStruct>
<Name>InternetGatewayDevice.ManagementServer.ConnectionRequestUsername</Name>
<Value xsi:type="xsd:string">ftacs</Value>
</ParameterValueStruct>
<ParameterValueStruct>
<Name>InternetGatewayDevice.ManagementServer.ConnectionRequestPassword</Name>
<Value xsi:type="xsd:string">ftacs</Value>
</ParameterValueStruct>
</ParameterList>
<ParameterKey>6357545</ParameterKey>
</cwmp:SetParameterValues>
</env:Body>
</env:Envelope>

At the end we had still some errors :

cwmp_handle_messages(369): acs response message is empty
cwmp_inform(314): handling xml message failed

Could be still something wrong at the server side?
In attachment the last capture.
Thanks

 looks the same problem. looks an interoperability problem. looks an xml parse problem. I will investigate the problem in the next release

 Thanks for your response. Could you please confirm me that this last part in not related to the http but to the cwmp protocol? In case of positive response I think would be necessary to manage this response inside the cwmp.c.
Best Regards

 I had applied the same approach also on the cwmp.c file with a return 0 at the beginning of the function:
int cwmp_handle_messages(void)
At the end of the transaction I received this at cli session :
Mon Jun 29 16:33:46 2015 daemon.debug easycwmpd: receive InformResponse from the ACS
Mon Jun 29 16:33:46 2015 daemon.debug easycwmpd: external: execute apply service
Mon Jun 29 16:33:46 2015 daemon.debug easycwmpd: external script exit
Mon Jun 29 16:33:46 2015 daemon.debug easycwmpd: end session success

Could you please confirm that could be a possible fix, for the moment?
In addition I also uploaded both cli logs and capture from the device.

 I can not confirm if it's a http problem or xml parser problem now, I have to investigate. But it's very likely an xml parser problem. And you can noht fix the problem wirth the same way (by adding return 0) because the cwmp should parse the cwmp request from the acs.

 Thanks for the update. If you will want to test this release or the next one here the references of the demo/test server that you can use for verifying interoperability:
