Phone or module GPS

With a GPS module connected to a Heltec Lora, does the GPS data come from the phone or the module? Is selection possible or not necessary as the module defaults.
Thanks for the help.
Cheers, Bill

There is no gps on the heltec

Garth, I have added a GPS module to the Heltec.

you can confirm device GPS activity through the serial log. your phone location isn’t used unless you enable the feature.
