Implementing a standard GPS communication protocol in Python

sebi53614 years ago

I have a A9G development board, a board with GPS and GPRS features, that runs MicroPython (Python for MCUs) thanks to this work.

My goal is to implement a standard GPS communication protocol in python to interface the board with Traccar.

Thanks,

I think the simplest option would be OsmAnd:

https://www.traccar.org/osmand/

It's a unidirectional HTTP-based protocol.

Neat! Thanks!!

Anton, just a subsidiary question:
When do you plan to release the replay feature?
(I have seen this is WIP in GitHub.)

Where did you see it?

Any chance to see this feature soon?
It would be neat to visualize previous routes, not only real-time routes.

There is a report to visualize previous routes. I don't really understand what "replay" adds over existing report.

Indeed, sorry I missed that feature.
(Looking at the bottom right to find the icon is not that natural to me...)
Thanks!

Is there the possibility to see the evolution in time of the position(s)?

I played a bit with the interface and find it really good the way it is.
Thank you!

For people curious to know how the MicroPython code running on the A9G board looks like:

import cellular
import gps
import socket

ID = 1234567 # Same arbitrary number as in Traccar
url = "demo.traccar.org"
port = 5055

cellular.gprs("internet", "", "") # Adjust with your APN credentials

gps.on()
loc = gps.get_location()

s = socket.socket()
s.connect((url, port))
s.send(bytes('POST /?id={}&lat={}&lon={} HTTP/1.1\r\nHost: {}:{}\r\n\r\n'.format(ID, loc[0], loc[1], url, port), 'utf8'))
s.recv(50) # Should be b'HTTP/1.1 200 OK\r\ncontent-length: 0\r\n\r\n'
s.close()

cellular.gprs(False)
