The motivation is to have a simple way to be tracked while running, walking or trekking. In my case, I'm going to run (well, I think I should say walk) the ultratrail 101 Km of Ronda in Malaga, South Spain. I want to have some way to be tracked from home (just recording the track is not a problem with nice pieces of software like ORUX MAPS) and this is a simple, yet functional proof of concept. USE IT AT YOUR OWN RISK, AS IT IS A EXPERIMENTAL AND EDUCATIONAL SOFTWARE NOT INTENDED FOR ANY SAFETY/EMERGENCY APPLICATION
La motivación es tener una manera sencilla de ser seguido desde casa mientras se corre, pasea o hace senderismo. En mi caso, voy a correr (bueno, yo diría andar) la prueba de ultratrail 101 Km de Ronda. Me interesa tener un medio para poder ser seguido desde casa y esta es una prueba de concepto simple aunque funcional. ESTE ES UN SOFTWARE EXPERIMENTAL Y EDUCACIONAL, SIN INTENCIÓN DE SER USADO PARA NINGUNA APLICACIÓN DE SEGURIDAD/EMERGENCIA. ÚSALO BAJO TU PROPIA RESPONSABILIDAD

To be able to track, you need:
- Account in a MQTT broker site like cloudMQTT
- QPython installed in your mobile devie (MUST BE ANDROID), as well as paho-mqtt module
- Python 2.7, paho-mqtt and QGIS installed in your system
First you must modify the script according to your server, port, etc. configuration Then run the DEVICE.py script in your cell phone. I suggest you to use QPython QRCode service to get the code in:
Yo can do it by copy-pasting the code. I suggest you to remove the license information, generate the QRCode with ECC set to L and Size to 10 and open the resulting QRCode in a new browser tab to be able to scan it with the phone
On tracker side, you must run TRACKER.py script to get the data from the mqtt broker. The script saves the received data to a file called tracking.csv. You could create a file before with a suitable header. Now the fields are: mobile_id;point_id;lat;lon
To show the tracked points over a map, just load the file tracking.csv as a CSV layer in QGIS enabling file whatching, so everytime a new point is appended by TRACKER.py it is shown on the map.
If you want to track many runners/vehicles at the same time, in priciple it should be as easy as running the DEVICE.py script in each of the devices, ensuring they have properly set the mobile_id variable to something meaningful (of course, the mobile_id MUST be different to make sense) and then set layer style in QGIS to categorized, categorizing by joining mobile_id and last field.
A lot, and for instance
- Because all data tranmsission will be through GSM connections, and because high chances of running into no coverage zones, store-and-send procedures for positions.
- Convert the track points to line automagically
