Please find the below Packet received as push notification from meter when we switched off the meter power. Hope this would be power failure notification.
00 01 00 01 00 40 00 6A DB 08 47 4F 45 00 00 37 45 14 82 00 5D 30 00 00 64 4B 09 91 4F A4 D5 38 05 64 48 E3 35 1A DB 5C 7E CE 3A E0 93 79 A5 DD 5B 7A 65 49 6D 29 B8 01 44 EE 76 53 9A 63 10 76 89 C0 0B 33 E1 B5 C5 69 7C 88 71 F6 EC F9 2D FD F2 5F 74 65 41 08 F0 30 27 20 37 21 D1 3C 99 A2 BE 8F 55 28 06 FF 8E D0 54 3A 88 D0 1C C7 73 E3 7C 82

How could we decode the above packet if it is encrypted one, with AES 128 Algorithm? Alteast can we get any document which explains the parsing of above packet?

Hi,

This data is encrypted. Do you know the keys? You need authentication and block cipher keys to make it work.

You can use GXDLMSClient for this.

GXDLMSSecureClient cl = new GXDLMSSecureClient(true, 0x40, 1, Authentication.NONE, null, InterfaceType.WRAPPER);
cl.Ciphering.BlockCipherKey=
cl.Ciphering.AuthenticationKey=
GXReplyData rd = new GXReplyData();
cl.GetData(reply, rd);

BR,
Mikko
