Converting Hex Data

How do I convert the hex data for me to consume data? Should I convert it to ASCII or text? I am not seeing the full string getting converted perfectly.

Do you want to provide the HEX in question? What device are you using?

lets say i want to convert this Lat 0x02 0x7A 0xC8 0x87 and Lon 0x0C 0x46 0x57 0xE6 to readable format , how do i do it . I am using GT06N

And it's related to Traccar how?

i am trying to find how this is being handled in traccar and converted

i was looking at the API and seeing how it is getting converted
