How to prepare data to change the key after encryption. Found the C++ example in GlobalKeyTransfer(). Not sure how to convert it to C.
The expected DLMS translator output:

<MethodInvocationParameters>
<Array Qty="01" >
<Structure Qty="02" >
<Enum Value="02" />
<OctetString Value="24 bytes key" />
</Structure>
</Array>
</MethodInvocationParameters>

Thank you.

how do i change the mechanism name that's used to connect to a meter?

i'm trying to connect to an L&G E355, "Management Access" port (1) using GMAC, but i'm running into these bugs:

- when i change the "Authentication" drop-down in the "Device Properties" dialog, and click "OK". the "General/Command line parameters" textbox doesn't update. i have to select a different meter and then return back to the meter i edited for that textbox to update and reflect the option that I selected in the dialog.
