Best Practice

Check Port and Payload Header in your decoder

    if(byte[0] == 0xbe && byte[1] == 0x02 && byte[2] == 0x02)
    {
        if ( port == 190 ) 
        {       
            // detected Parametric TCR Configuration Payload V2
        
        }


        if ( port == 15 ) 
        {       
            // detected Parametric TCR Application Payload V2
        
        }
    }
