– Your VFRnav Team
Good morning,
Is it the same as with the last update, that it takes a while for my phone to install it? Or do I need to do anything to get the latest version?
Kind regards!
Hello Sonja,
Android or Apple? Unfortunately, with Apple the releases always take a bit longer than with Google. There’s

Exactly as Karsten wrote. The changes are checked by Google (Android) and Apple prior to release. Only after the (successful) check is the rollout initiated. Altogether, it takes anywhere from a few hours to a few days.

Thank you for the update.

Thanks for that – it’s exactly what I wanted.

Re: Version VFRnav 4.17.2
here: Under “Signal Quality” no GPS display (stuck on “Waiting for GPS…”)
Dear VFRnav team,
I am very satisfied with VFRnav and have been using it for several years. Thank you very much for the excellent work and service. My paired STRATUX system is also working flawlessly (Android Samsung A52 5G). I recently updated to the new version VFRnav 4.17.2, and when checking the GPS signal quality no signals are shown and
Addendum regarding the missing GPS signal indicator (“Waiting for GPS…”):
I have noticed with my VFRnav-STRATUX connection that when I connect via the WLAN network “STRATUX”, the VFRnav app’s “External Data Source” also displays the STRATUX GPS reception graphically. Unfortunately, I cannot access the internet via “Mobile Data”, which is important in flight for NOTAMs or weather
Hello Santiago,
please go back into the settings and activate the -Network- option again
and then check these applied settings.
Regarding the second point of your question:
Please read the topic -VFRnav and Stratux-. Feel free to download the documentation linked there. Possibly the topic described on page 12 is a potential solution for you. Although the hotspot variant described is still marked as experimental in version 0.32, it actually runs well. Which version is your Stratux? Your suggestions will certainly be reviewed! Thanks for that..
simply fly and aviator greetings, Karsten
…I’ve linked it for you again here 
Hello KBfly,
Thank you very much for the quick response and the “STRATUX” documentation, which helped me a lot. I installed version 0.32. Everything is running smoothly.
For the “AP+Client” setup I hadn’t selected the button “Add WiFi Client Network” because I considered it non-functional due to the considerably weaker display and assumed the client network would be adopted automatically in the phone’s settings. After entering the details of my “Client Network”, the STRATUX satellite graphic is displayed and Internet access works at the same time. Basically very simple, “I didn’t see the option at CAVOK”.
Only under the “Signal Quality” setting it remains at “Waiting for GPS…”. VFRnav still shows the current position correctly.
According to the app “GPSTest”, my phone receives GPS perfectly and shows all available satellites. I couldn’t change anything here.
Thanks again and fly safe,
Horst
Hello Horst,
I’m pleased that you like my “handmade” documentation. I’ll need to get back to it and bring it up to date.
I assume your phone is correctly connected to the Stratux Wi-Fi.
Please check here, just to be sure, whether you have GPS data reception in the Stratux web interface:
and further down under AHRS GPS, whether GPS is green here:
Why this check?
The most common, and usually sole, cause of a missing GPS signal is an unreliable power supply!!! After extensive tests, the Tizi adapters have proven to be functionally reliable for in-aircraft power. For operating the Stratux at home, I exclusively recommend the original Raspberry Pi power supply. (for Pi 4 and later, note the USB-C connector!) If everything is OK here, let’s have another look at VFRnav.
In your image above, do you see ‘only’ the Level GPS indicator and not the GPS information from Stratux? Or are there no GPS data at all?
Note: If the external GPS (in this case from Stratux) fails, or the connection to Stratux drops, it will automatically switch to the phone’s GPS.
This is a safety feature of VFRnav to ensure GPS reception at all times.
Perhaps this is happening to you?
Please check again and let me know. Thank you! …I have not been able to replicate this with my test devices here.
Good luck and happy flying,
Karsten
Hello Karsten,
thank you very much for the very prompt update. The “signal quality” display is back. Many thanks also for the explanation of the fail-safe mechanism and the issue with the power supply; it was exactly as you described. The USB cable was only partially suitable for me, too. Now everything is back to how it should be. Great service from you.
Aviator greetings
Horst
…great Horts🙂…thanks for the feedback.
Flying regards, Karsten
…since we were on the topic of SatNav data:
If you’re ever curious about which SatNav data are currently being made available to VFRnav for processing, just tap on one of the reception signal bars.

In the current 4.17 version, the saved routes no longer load.
Hello Manfred,
Welcome to the forum.
What exactly happens when loading? Is there an error message?
Which device and
Hello Hermann,
yes😪…I can confirm that too! (just did a phone test)
→ So do randomly created routes that weren’t saved now persist after a restart? …is that how it’s supposed to be?
Flying greetings on holiday,
Karsten
Yep, that’s right. It was often requested. (However, it’s not my preferred behaviour and will be configurable in the future.)
Happy flying
Hermann
Note: ..this only occurs with old saved routes. You can create new routes, save them and reload them.
Classic? …Rights?
Best regards, Karsten
