The GPS is not working on auto-start

Eric Katzfey

@Eric-Katzfey The LED on the GPS unit is a general purpose status LED for PX4. If it is blinking red then there is some sort of fault condition that would prevent you from arming the drone. If you connect to QGC it will (usually) alert you to what the issue is.

Eric Katzfey

@Captain-7th I'm not sure what it means to be a hidden network. We have not tried with anything like that. Can you try it with a non-hidden network and see if it works properly with that?

Captain 7th

@Eric-Katzfey I am working with this drone at my university. The university network is hidden (SSID is not visible to everyone!) and you cannot access it without MAC address registration in uni's systems.

I have arranged to add the drone's MAC address to the system. I was wondering if it recognizes the hidden networks when we are working with voxl-wifi, station mode, or not? Because I tried to give the SSID and the password, and it shows a successful configuration message on the terminal. Then, when I write voxl-my-ip in the terminal, is does not print anything! Nothing at all! I tried even to ssh to have access to it, but is does not recognize it!

Do you have any idea how I can configure this or not?

Captain 7th

@Eric-Katzfey I tried outside with a clear sky, and it is working now. Why it is not working inside?

Eric Katzfey

@Captain-7th There are many explanations for how GPS works online and the reasons why it doesn't work well or at all indoors.

Captain 7th

@Captain-7th @Eric-Katzfey Can you help me with this issue? The wifi issue for the hidden network?

Captain 7th

@Eric-Katzfey, I have tried using a non-hidden network, such as a mobile hotspot, and it works. But I am struggling to connect it to a hidden network.

I am working with this drone at my university. The university network is hidden (SSID is not visible to everyone!), and you cannot access it without registering your MAC address in uni's systems.

Nothing at all! I even tried to ssh to access it, but it does not recognize it! The drone does not get connected to hidden network!

Eric Katzfey

@Captain-7th We have never tested with hidden networks so I'd say that it isn't supported at the moment.

Captain 7th

@Eric-Katzfey Thanks for the reply.

I have another trouble.

I am trying to run the first ROS test with https://docs.modalai.com/mavros/. My controller does not work now (previously, I had connected the RC to the drone), and I have trouble switching the drone mode (with ‘offboard’ and ‘manual’ modes). Is there any other approach to switching between modes other than RC?

Also, is there any other way to arm or disarm the vehicle without RC?

Thank you for your time and consideration. I am looking forward to hearing from you.@Eric-Katzfey

Eric Katzfey

@Captain-7th There are many ways to arm and switch modes other than RC. They can be done from the console in PX4, from QGC or any other ground control station, with MAVSDK, etc.

Captain 7th

@Eric-Katzfey Could you please tell me which part I should study in the documentation regarding PX4 or QGC?

Jetson Nano

@Captain-7th Once you connect the drone to QGC, it'll show some mode in the top left, you can click on that to change to a different mode. When you click on the ready to fly message on the top, it'll show an button called arm for arming the drone.

@Jetson-Nano @Eric-Katzfey Thank you for your reply. I have trouble running the mavros_test Project (simple-example) (https://docs.modalai.com/mavros/#mavros_test-project-simple-example).

I followed all the instructions carefully, and when I ran:

cd /home/mavros_test
./run_mavros_test.sh

I got this on the terminal:

voxl2:/home/mavros_test(simple-example)$ ./run_mavros_test.sh

Note 2: I could manually arm/disarm the Sentinel drone with QGC and RC. The motors are working properly. But this ros example is not working here! Can anyone help me?

Note 3: I also tryied to change the mode channel to 5 and 6, but still not working!
