+A NRF sample project for SoftDevice 140 on a nRF52840DK. The device asks for used input for GPS coordinates. 
+The coordinats should be given over UART with the following pattern: xxx.xxxxx for both longitude and latitude. The device then transmits
+the coordinates as a BT beacon advertisement data with a specified name. The data is a part of the manufacturer data and is shown in 
+hexadecimal format. Negative values are not specifically adressed and at the moment 2's complement for the negative numbers is used that
+is generated by the example software.
