Now i want to test notification service with Suite0, i get frame from meter but facing problem in deciphering frame is bellow

7E A0 55 61 00 02 BA 69 7C 7F 34 E6 E7 00 CF 44 30 00 00 00 06 A0 5E C5 68 90 64 7D D4 BE 51 04 86 FE B0 53 20 07 A1 3F 1B 2D E9 13 BB 50 B9 53 90 02 1B 31 DF AA 08 94 FE A2 62 64 70 2C FB BB 8C D6 BD 1D 03 84 1B E1 70 BF DC 62 DF 1D 6E 59 50 60 33 8E 7C 59 7E

encryption key: 01234567890abcdef
authentication key: 01234567890abcdef
server system title : 33 44 4C 28 09 19 00 46

Is we are doing something wrong?

Hi,

Hi,

Are you using Gurux stack to send the push messages? What programming language you are using?
Block and authentication keys can't be correct, because there are 17 bytes and the key size must be 16 bytes.

Hi,

Hi,

I did try with your new keys and the decryption failed. There must be something wrong how you encrypt the data, but it's impossible to say what is the reason. Check your keys.
