Hi all,
I'm relatively new to this hence struggling a bit. I recently got hold of a RPi B+ and a ublox GPS chip https://u-blox.com/en/gps-modules/pvt-modules/pam-7q-gps-antenna-module.html
I need to get NMEA data out of this GPS chip. I have read tutorials about freeing the UART port by editing the line in /boot/cmdline.txt and commenting the last line in /etc/inittab and have managed to do so. Now as far as I know from online tutorials, GPIO15 (pin 10) is the RxD and GPIO14 (pin 8) is TxD. So I have the connections set as such:
| RPi | GPS |
|---|---|
| 3v3 | Vin |
| GND | GND |
| pin10 | TxD |
| pin8 | RxD |
Now in my RPi what do I have to do in order to receive NMEA strings?
I have tried this tutorial and several others which sort of say the same thing but haven't had much luck.
