uint8 const* is a ptr defining pTagID

if (tlv_tag_compare(tags.pTagID, "\x9F\x91\x8B\x15"))
{

uint8 *ptr = tags.pTagID;
uint8 ch[4];
uint8 k=0;
for(k=0; k<=3;k++)
{
ch[k]=*ptr;
++ptr;
}
uint8 temp[4];
sprintf(temp,"%02x%02x%02x%02x",ch[0],ch[1],ch[2],ch[3]);



Question I am trying to see what teh content of pTagID is which is a Ptr
the value I am getting in temp is not 9F918B15.... why not
How do you examine the value of that pTagID ?


Thanks

See if this is what you're looking for.
