Waveshare-GPS

Simple script to use Waveshare GSM/GPRS/GNSS/Bluetooth HAT for Raspberry Pi GPS functions

Usage

./gps.sh  {loc|time|status|poweron|poweroff|towertimesync}

• loc = show current location
• time = show time
• status = show gps timesync settings, gps power status and location fix status
• poweron = power on gps functions
• poweroff = power off gps functions
• towertimesync = adjust clock from cellular tower. With initially correct time satellites found faster.

Output

loc command outputs raw AT command, response and decoded data
