After installing libgps_3.7-1_ar71xx.ipk, libgpsd_3.7-1_ar71xx.ipk and gpsd_3.7-1_ar71xx.ipk in my Pineapple Nano everything worked smoothly.
I had installed ADB (opkg install adb) and share my Android GPS with Pineapple Nano via a NMEA USB connection.
About WIFI Locator ?, How can I help ?
Regards.
