If you connect JF2 module with GE865 module you must use UART configuration.
Using an external host, if you want use I2C configuration, you need to plugging on
PL302 two jumpers in positions 3-4 and 5-6 in order to connect pull-ups in SDA and SCL
lines.

GPS power-on management
JF2 module power on/off can be controlled by an external host signal or it is possible to
have the automatic module transition to the full power state by tying the SYSTEM-ON
output to the ON-OFF input. The table below shows how to set these two options:
Power Mode
10-12 and 19-21 pins shorted in
PL302
Full power mode
11-12 pins shorted in PL302
ON/OFF controlled by an external
host signal
