Thanks! I have merged this to my forked repository

Thanks for the PR.

Tried to use it on my postmarketOS Linux phone

1. Starting a fake GPS stream

virtualgps.py -c virtualgps.conf -p warsaw --verbose
Streaming virtual location (Lat: 52.13791, Lon: 21.00704, El: 100.0) to serial GPS device /dev/pts/3

2. configured gpsd

cat /etc/conf.d/gpsd 
GPSD_OPTIONS="-n -D 1"
DEVICES="/dev/pts/3"

3. started gpsd

sudo rc-service gpsd start

4. installed gps with your waydroid_script fork
   supplied /var/run/gpsd.sock with baudrate 9600
5. opened comaps on waydroid but cant get any position

@Lolmc0587 updated my comment, not yet working for me

[Lolmc0587]

Have you updated your LineageOS version to the latest or added the dialout group? Mine works perfectly on Ubuntu.
If it doesn’t work, can you send me the waydroid_logcat.log?

[onny]

Yes it's running Android 13 now. On the host system (postmarketOS/Alpine Linux) I added my user to the dialout group.

Maybe I'm going to test it on my desktop PC first (NixOS)

Should this be offset?

[Lolmc0587]

if i do container.upgrade(), this config will be reset.
i don't know how to solve this, so in this case it must be that

Thanks for your work!

Unfortunately this does not work for me either. I tried using it with the gpsfake tool since I have no gps receiver laying around. Running on Ubuntu 24.04 and waydroid 1.5.4

What I did:

GPS NMEA file to feed:

Run the gpsfake service:

sudo gpsfake --speed 9600 --slow <nmea data file>.nmea -D4

(...)
gpsd:INFO: <= control(8): adding /dev/pts/14
gpsd:INFO: stashing device /dev/pts/14 at slot 0
(...)

Setup waydroid (lineage-20.0-20250809-MAINLINE-waydroid_x84_64):

sudo waydroid init

Install the gps using your script:

sudo ./venv/bin/python main.py
-> Android 13
-> Install
-> gapps, gps
-> /dev/pts/14
-> 9600

Then waydroid session start and waydroid show-full-ui but there is no location available in any navigation app (google maps, OsmAnd).

I haven't tried the gpsfake yet. I will have a look at it.

[Lolmc0587]

Maybe that will works

[Lolmc0587]

Please don't use that pts device, you can set the fake gps device to like /dev/ttyGPSD
If you can't, follow the command below

sudo ln -s /dev/pts/<yourdevice> /dev/<nameyouwant>
sudo chmod 777 /dev/<nameyouwant>

[doeni98]

Did not find any way from the gpsfake docs to specify the tty device path. Anyhow with the symbolic link it works like charm!

Thank you very much!

[mburucuyapy]

will this also read from /dev/ttyACM0 or just GPSD?

[Lolmc0587]

will this also read from /dev/ttyACM0 or just GPSD?

Yeah
Just don't use /dev/pts/..
