Anti-lost pendant Help

Hi,
I wanna make an anti lost pendant (ID design completed) , assuming to use Grove-GPS & mini BLE to achieve.
Now here is the question, where i can find the code to make this possible?
And is that possible to shape the board like the picture ?
Hope anyone interested in this program could contact me.
