» GPRS SIM928A 24: Getting GPS info

This example shows how to get parsed NMEA strings and shows them by serial monitor

Required Materials

1 x Waspmote
1 x Battery
1 x GPRS_SIM928A module
1 x GPS antenna

Notes

- GPS antenna should be outdoor in order to get GPS signal from satellites
- GPRS_SIM928 module must be powered with a battery
- When GPRS_SIM928 is in use, interrupts can't be used
- This example can be executed in Waspmote v12 and Waspmote v15
