Communication between two iOS devices is established by connecting both devices via BLUETOOTH or Wi-Fi. The procedure to start the connection is as follow:
- In the master device (the one with GPS):
- At system level, open Settings and select Wi-Fi and turn it OFF.
- At system level, open Personal Hotspot, enter a password of your choice and turn Personal Hotspot ON. When it shows Wi-Fi is off, select Bluetooth and USB only.
- In the slave device (the one without GPS):
- At system level, open Settings and select Wi-Fi and turn it OFF.
- At system level, open Settings and select Bluetooth and turn it ON.
