  2. Parse Compact Frame CF49

Parse compact frame CF49

By Catalin, 2 February, 2026

Hello,

Using GXDLMSSecureClient with Security.AuthenticationEncryption I've managed to receive the push message sent by a Honeywell gas smart meter. The OctetString value seems to be a compact frame, more precisely CF49. There is a posibility to parse the OctetString value and get the values as a "readable format" ?

Thank you in advance

I want to add, also, that CF49 is defined in UNI/TS 11291-12-2 standard. Thank you
