I got AARQ failed.

Hi, Gurux Administrator

My meter is made by Taiwan Power Company.

I spent some time on attempt to figure out how to change the control field.
fortunately, I did it.Here is my solution:
1)Open the file "GXDLMS.cpp".(~/Gurux.DLMS.cpp/development/src/GXDLMS.cpp)
2)In the line:821, there is a if-else, like this:
if (p.GetCommand() == DLMS_COMMAND_AARQ)
{
frame = 0x10;
}
else if (p.GetCommand() == DLMS_COMMAND_DATA_NOTIFICATION ||
p.GetCommand() == DLMS_COMMAND_EVENT_NOTIFICATION) {
frame = 0x13;
}
3)Change "frame = 0x10" into "frame = 0x13",like this:
if (p.GetCommand() == DLMS_COMMAND_AARQ)
{
frame = 0x13;//I change 0x10 into 0x13
}
else if (p.GetCommand() == DLMS_COMMAND_DATA_NOTIFICATION ||
p.GetCommand() == DLMS_COMMAND_EVENT_NOTIFICATION) {
frame = 0x13;
}
4)Done. Anyway, my meter dose not accept the I-frame, so the "frame = 0x10" is useless.
This solution is rough, but it work.

Hi Mikko
I increased the authentication level ,but I got "AARQRequest failed 279."
My command line like this:
pi@raspberrypi:~/Gurux.DLMS.cpp/GuruxDLMSClientExample/bin $ ./gurux.dlms.client.bin -S /dev/ttyS0 -a HighGmac
InitializeConnection
AARQRequest failed 279.

Here is the content of trace.txt:

What does "AARQRequest failed 279." mean?

Besides, I got two questions.
1) I changed the AP-title into "VER00001",and here is what I did in GXDLMSSecureClient.cpp:
CGXDLMSSecureClient::CGXDLMSSecureClient(bool UseLogicalNameReferencing,//called in main
int clientAddress,
int serverAddress,
//Authentication type.
DLMS_AUTHENTICATION authentication,
//Password if authentication is used.
const char* password,
DLMS_INTERFACE_TYPE intefaceType) :
CGXDLMSClient(
UseLogicalNameReferencing,
clientAddress,
serverAddress,
authentication,
password,
intefaceType), m_Cipher("VER00001")//originally it is ABCDEFGH
{
m_Settings.SetCipher(&m_Cipher);
}
However, I saw "A6 0A 04 08 41 42 43 44 45 46 47 48" in AARQ.
Why dose it not change ?

2) My meter suggest that the Application-context-name should be Logical_Name_Referencing_With_Ciphered.
But what instruction should I use in command line to do that ?
