Hi,

It's not so easy. There are multiple settings that must be set before GMAC authentication can be used.

Do you want to use just GMAC or also the ciphering (encryption)

Hi,

Get the latest version from the simulator. There is GMacWithAuthenticationEncyption.xml template for GMAC with authentication encryption.

Establish the connection to the meter.
-h METER_IP -p 4061 -c 1 -a HighGMAC -P Gurux -C AuthenticationEncryption -T 4775727578313233 -A D0D1D2D3D4D5D6D7D8D9DADBDCDDDEDF -B 000102030405060708090A0B0C0D0E0F -v 0.0.43.1.0.255 -t Verbose
