gps2mqtt

A shell script based on atinout and mosquitto_pub to publish GPS coordinates from a Raspberry Pi powered WaveShare GPS/GSM modem

Requirements

Built for the WaveShare GSM / GPRS / GNSS HAT for Raspberry Pi (https://www.waveshare.com/wiki/GSM/GPRS/GNSS_HAT)

To use this script you'll need the atinout package This Smart House Version found here:

http://github.com/ThisSmartHouse/atinout

If you don't use the version maintained by This Smart House this script will likely not function properly as it will not time out when trying to determine if the GPS module is alive.

You also need the WiringPi gpio utility to auto-power-on the HAT if it happens to be off:

It is also assumed you have the mosquitto-clients package installed

Setting up

Install atinout (forked version) and mosquitto-clients Edit the baud, tty, host and topic variables set at the top of the script and run!

$ git clone http://github.com/ThisSmartHouse/atinout
$ cd atinout
$ make
$ sudo make install
$ cd ..
$ sudo apt-get install mosquitto-clients
$ sudo apt-get install wiringpi
$ git clone http://github.com/ThisSmartHouse/gps2mqtt
$ nano gps2mqtt/gps2mqtt.sh

<edit configuration> 

$ sudo cp gps2mqtt/gps2mqtt.sh /usr/local/bin
$ sudo chmod +x /usr/local/bin/gps2mqtt.sh
$ crontab -e
