Hi,

Hi,

What device did you try to read? This manufacturer hasn't support GMAC before.
Change device manufacturer to Gurux and update your settings and try to read again.

Hi,

Hi,

There is unknown tag in the data. I believe that you are adding extra bytes in ciphering to the data.

Hi Mikko,

Hi Mikko,

Yes you are right it was due to corrupted buffer.

Thanks a lot.

Hi Mikko,

Hi Mikko,

My new implementation was extra incrementing the response buffer index by Size of Security header and Ciphered Content which the code has already taken cared of.

Thanks for your Help !!!
