gpsd and Android Auto

[F4u5t]

This isnt a Hudiy issue but i though maybe I should post it to save someone else the trouble.
I have Hudiy running on a Lenovo Yoga laptop, running Debian Trixie...
I have a U-Blox gps usb dongle connected that is feeding a speedometer python app I made, which is set as the desktop background.
That part works great, it even has toggle switches that control rpi gpio, also usb connected.

I put Hudiy on it to also get Android Auto, which works, even got my speedometer as a overlay in Navigation so I always see it....

Took for a test drive today, and Andoid Auto navigation is all over the place, its fine for a bit, then it puts me way down the road....my guess is that gpsd is interfereing with the navigation signals Android Auto is reading, so unless i can find some way to isolate them its kinda usless.

Do you mean that the GPS module connected to your laptop is causing navigation issues in Android Auto?

In an upcoming version of Hudiy, we can add a toggle to prevent Hudiy from sending GPSD data to Android Auto. This would force Android Auto to rely solely on the phone's GPS.

As a workaround, you can change the port that GPSD listens on. Hudiy connects to GPSD using the default port (2947). If you change the port, Hudiy simply won't connect to GPSD and won't forward any data to Android Auto.

The easiest way to change gpsd port is modifying gpsd config

sudo nano /etc/default/gpsd

then in GPSD_OPTIONS you can add --port 2948 (or any other unused port number)

Code: Select all

# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.
DEVICES=""

# Other options you want to pass to gpsd
GPSD_OPTIONS="--port 2948"

# Automatically hot add/remove USB GPS devices via gpsdctl
USBAUTO="true"

then restart the gpsd service (sudo systemctl restart gpsd) and remember to update the port number in your script.

well, there is hope this, thanks for that! but yeah, i found this project last Friday, and im sure you noticed from my constant messages i been digging into it since, but i figured out widgets, shortcuts and overlays, Hudiy - everything works perfect stationary in my office, so today i throw the laptop in the Jeep and take it for a test, i have my U-Blox gps dongle being read by gpsd, which is displayed in Hudiy as a widget, also a small version in Android Auto as a overlay, everything "worked" but the Android Auto navigation was pretty inaccurate, it seemed to be having trouble with what road i was on, and sometimes my location would jump way up the road, it was pretty odd. Im only guessing that gpsd had something to do with it, cause ive never had issues with AA in other cars

Yes, it looks like the issue might be related to the data sent from your U-Blox GPS module to Android Auto. Please let us know if changing the port to prevent Hudiy from sending data from GPSD to Android Auto fixes the problem.

For better convenience, we will add a configuration option in the upcoming release to easily enable or disable sending data from GPSD.

Could you also share the specific model of your U-Blox module? We will try to acquire the same unit to test its accuracy and see if there is any room for improvement.
