Hello,

I'm testing the sentinel drone for outdoor flight and we have no GPS data on QGroundControl.

The light for GPS fixed is blinking, indicating that the sensor is getting signal and being fixed.

This is the list of voxl-services running:

![image.png](https://forum.modalai.com/assets/uploads/files/1681314234893-image.png) 

Some things that appear to be wrong:

* NUTTX console is not responding to any commands, on QGC through Wi-Fi;

* When I tried to upload the parameters file "voxl-4-params/params/v1.12/ekf2_outdoor_gps_mag.params" there were no problems, but I still have no GPS and when I tried to upload "voxl-4-params/params/v1.14/EKF2_helpers/outdoor_gps_baro.params" the following error appears in QGC: "Parameters are missing from firmware. (...) Missing params: 1:EKF2_EV_CTRL, 1:EKF2_GPS_CTRL, 1:EKF2_HGT_REF, 1:SYS_HAS_GPS".

Would appreciate any help solving this issue. Thank you!

@andremoura The VOXL2 version of PX4 is different than what you get on a standard Pixhawk style flight controller (e.g. flight core). On VOXL2 the implementation is split between the application processor (running Linux) and the Sensors DSP (Running Qualcomm's Qurt RTOS). So Nuttx is not used at all on VOXL2 PX4. However, there are still ways to interact with PX4 via the console.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-12 16:54:12 UTC

@andremoura One way to interact with PX4 on VOXL2 is using PX4 command aliases. For example, if you want to run the command `listener sensor_gps` to see if the GPS unit is publishing GPS data then you could use an adb shell to enter the following command alias `px4-listener sensor_gps` and it will show you the latest published data from the GPS sensor or say never published.

I tested the "px4-listener sensor_gps" command, as you proposed and the output was "never published", even though the GPS is fixed.

I also tried "px4-gps status" and got "INFO [gps] not running". Then I also tried px4-gps stop and start, but no difference in the status.

@andremoura The GPS unit will come up and get a fix on it's own after it has been powered on so that doesn't indicate anything about the health of the connection to the flight controller. If the result of `px4-listener sensor_gps` is never published then there is likely a problem with your connection to the GPS unit. The GPS driver on VOXL2 runs on the DSP, not on the applications processor so you have to use `qshell` to interact with it. So, for status, you would use `px4-qshell gps status`. Have you made any changes to the Sentinel hardware or is it exactly the same as it was shipped?

@Eric-Katzfey The sentinel is as it was on arrival 2 days ago, no hardware changes.

We ran ```px4-shell gps status``` and got:
```
voxl2:~$ px4-qshell gps status
INFO  [qshell] Send cmd: 'gps status'
INFO  [qshell] qshell return value timestamp: 801929670, local time: 801931434
```

@andremoura Okay, that's not very useful. Let's try something else. First of all can you post the contents of the file `/etc/systemd/system/voxl-px4.service`? Then, stop the service from autostarting voxl-px4 with the commands `systemctl disable voxl-px4` and `sync`. Then reboot the drone. When you adb back in to the drone you can run `voxl-inspect-services` to verify that voxl-px4 isn't running. Then you can start voxl-px4 manually from the command line with `voxl-px4` and then post all of the output from that.

@Eric-Katzfey After manually stopping and starting the ```voxl-px4``` service, it has been working on startup.
Very strange, since when I first noticed the GPS issue, the service was running from startup but not receiving any data (as seen on my console print). However, now it seems to work every time we shut down and power on the drone.

Thank you for your help!

@andremoura Okay, that's unexpected. Oh well, at least it is working now! Let me know if it starts to give trouble again.

@Eric-Katzfey Unfortunately the GPS is not working as expected. Yesterday we were momentarily able to get between 9-12 satellites, which I think is a little low. With that number of satellites, we were not able to get GPS lock on the drone, QGC displayed an error related to GPS accuracy too low. Even after allowing to arm without GPS lock and flying at about 15 m, the number of satellites didn't change and we couldn't even put the drone in position mode, because of not being GPS locked. 

What we did to be able to even get those satellites was ```systemctl disable voxl-px4``` , ```systemctl disable voxl-mavlink-server```, rebooted the drone and, in two different ssh shells, ran both services manually. 

Today, using this approach, I'm not even able to get any satellites at all. All the following tests were done with the ```ekf2_outdoor_gps_mag.params``` configuration file from your Gitlab.

The output from ```voxl-px4``` was:
```
voxl2:~$ voxl-px4

```

Inside the pxh console, we ran the ```gps status``` command and got:

```
INFO  [gps] not running
Command 'gps' failed, returned -1.
```

I find this strange since when we ran the ```voxl-px4``` service it had the start command for the gps. Since gps was not running, I decided to test again the gps start by doing ```gps stop``` and then ```gps start -d 7 -b 115200```, that appeared on the output of ```voxl-px4``. The console output was:
```
ERROR [gps] GPS: failed to open serial port: 7 err: 2
```

We also tried the same with ```qshell```.
 ```qshell gps status``` outputted:
```

We also tried to stop and run it again with ```qshell gps stop``` and ```qshell gps start```.

After this, the output of ```qshell gps status``` was:

Any ideia of what the problem could be?

I also noticed the following errors on the ```voxl-px4``` output:
```
ERROR [muorb] SLPI: px4io read failed
ERROR [muorb] SLPI: px4io io_reg_get(0,0,1): data error -5
ERROR [muorb] SLPI: IO not installed

```
Is this normal?

Thank you.

@andremoura Yes, the errors related to px4io detection are expected since you do not have a px4io unit attached to the drone. And yes, you have to interact with things on the DSP (where the GPS driver runs) with `qshell` as you already figured out. Do you have any other Sentinel drones that you can compare against? Or other types of drones with GPS to compare against? When you are able to get 9 to 12 satellites what does `qshell gps status` show? It does appear to be wired up correctly as sometimes it is obviously communicating with the GPS unit.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-14 15:22:02 UTC (in reply to Andre Moura)

@andremoura It looks like there are at least 2 different issues here. One is that when you do see it working it has poor performance and doesn't get a lock. That is why I wanted to compare against other drones or other GPS units. If other units are working fine and this one isn't then maybe it's a faulty unit. If they all have poor performance then maybe it's something about the test location.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-14 15:25:52 UTC (in reply to Andre Moura)

@andremoura The other issue appears to be that you don't always get the driver to communicate with the GPS unit on startup. The start line in `/etc/modalai/voxl-px4.config` is `qshell gps start -d 7 -b 115200`. When you did `qshell gps stop` and then `qshell gps start` was it started with `qshell gps start -d 7 -b 115200` or just `qshell gps start`?

## Reply by Andre Moura · 2023-04-14 16:13:17 UTC (in reply to Eric Katzfey)

@Eric-Katzfey We don't have any other Sentinel drones. We have other drones with GPS, that detect at least the same or higher number of satellites but they all are able to GPS lock.

When we had that number of satellites, the ```qshell gps status``` seemed ok with number of satellites, latitude and longitude, but we aren't able to replicate that test right now because of bad weather conditions.

## Reply by Andre Moura · 2023-04-14 16:16:55 UTC (in reply to Eric Katzfey)

@Eric-Katzfey I will test the Sentinel drone on a new better location next week, if weather gets better, and I will get back to you.

## Reply by Andre Moura · 2023-04-14 16:21:16 UTC (in reply to Eric Katzfey)

@Eric-Katzfey GPS mostly hasn't beeen working on startup again.

We started it with ```qshell gps start```, but we also tested ```qshell gps start -d 7 -b 115200```. Both commands only worked a few times, we are not able to consistently start the GPS, having to stop and start again the service a few times before it works.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-14 16:27:31 UTC (in reply to Andre Moura)

@andremoura Is the LED on top of the unit (multicolor LED) coming on?

## Reply by Andre Moura · 2023-04-14 16:30:02 UTC (in reply to Eric Katzfey)

@Eric-Katzfey said in [GPS not working](/post/9658):
> @andremoura Is the LED on top of the unit (multicolor LED) coming on?

Yes, every time ```voxl-px4``` is running.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-14 16:42:21 UTC (in reply to Andre Moura)

@andremoura Okay, good. Holybro changed some of the components in their unit at one point and if that LED wasn't coming on it could indicate that it was one of the older units. But since it is on that indicates to me that it is the correct version of the Holybro unit.

## Reply by Andre Moura · 2023-04-14 16:45:56 UTC

@Eric-Katzfey Ok, new find! It seems that when ```voxl-px4``` runs, the GPS service isn't able to start immediately, but if we wait a for a bit and start it manually, it works.

Seems like something isn't ready to start immediately after ```voxl-px4```.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-14 16:53:25 UTC (in reply to Andre Moura)

@andremoura Interesting! Okay, how do you accomplish that? Do you mean you are stopping the service and then starting voxl-px4 later manually or you are leaving voxl-px4 service enabled but commenting out the gps start line in `/etc/modalai/voxl-px4.config`?

## Reply by Andre Moura · 2023-04-14 17:22:34 UTC (in reply to Eric Katzfey)

@Eric-Katzfey We are stopping the GPS service manually (```qshell gps stop```) and then starting it later manually (```qshell gps start```), not the ```voxl-px4```.

Do you want us to do the same test with commenting the gps start line in ```/etc/modalai/voxl-px4.config```?

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-14 17:29:39 UTC (in reply to Andre Moura)

@andremoura Actually, can you try removing the `-d 7 -b 115200` from the gps start line in `/etc/modalai/voxl-px4.config` and see if that changes anything? Thanks for trying all this stuff out!

## Reply by Andre Moura · 2023-04-17 14:47:01 UTC (in reply to Eric Katzfey)

@Eric-Katzfey Hello, today I tested removing ```-d 7 -b 115200``` from ```/etc/modalai/voxl-px4.config``` and it seems like the GPS service is working correctly on startup. I'm still going to test if I can get more fixed satellites and GPS lock on a new location with more open space and then get back to this post with more information.

## Reply by Andre Moura · 2023-04-17 15:42:03 UTC (in reply to Eric Katzfey)

@Eric-Katzfey On the new location, we were able to get GPS lock after fixing 12 satellites, which allowed for take-off. During flight we reached 19 satellites at one point. Getting GPS lock with this sensor is a bit challenging, our previous location didn't have that many obstructions, but everything seems to be working.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-17 16:02:21 UTC (in reply to Andre Moura)

@Andre-Moura Thanks for all of the testing! We really appreciate it, this is all great feedback! It seems that Holybro may have changed the default configuration of the units and that could be why it wasn't coming up properly.

## Reply by daniel · 2023-04-19 09:25:19 UTC (in reply to Andre Moura)

@Andre-Moura We have same issue here but we try to remove -d 7 -b 115200 from /etc/modalai/voxl-px4.config is still not working. Did you modify thr code like this?

Removing the 115200 baud rate is still not see GPS log.

@Andre-Moura Thank You! We fixed our GPS setting problem.

## Reply by JustinDev23 · 2023-04-26 18:16:17 UTC

@daniel what ended up being your fix? I was seeing the same issues yesterday with our Sentinel trying to do GPS only outdoor flights.  It wouldn't ARM due to the GPS Speed Accuracy. Flashing blue for a minute or two and then turning green after what i assumed was VIO getting healthy.

@Eric-Katzfey I don't want to use the Sentinel VIO so was hoping there was a GPS Only No VIO params file. It seems like the one posted on the git is still looking at VIO.

## Reply by James Strawson (ModalAI staff) · 2023-04-26 18:37:10 UTC

you will likely want to configure px4 params to suit your exact use case, e.g. some people will want it to arm without a gps lock, some won't. As a starting point we have "helper" files that can be loaded through QGC that set up the handful of relevant PX4 params for indoor vs outdoor flight

Here is the outdoor helper for px4 1.12:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/blob/master/params/v1.12/ekf2_outdoor_gps_mag.params

And the helpers for PX4 1.14:

## Reply by JustinDev23 · 2023-04-26 18:44:01 UTC (in reply to James Strawson)

@James-Strawson Awesome, thanks I am going to load the outdoor params. Just didn't know if someone had already blessed us all with a known good config.

## Reply by JustinDev23 · 2023-04-27 14:33:12 UTC (in reply to James Strawson)

@James-Strawson If i stop and disable the VIO server will that still allow GPS to pass through? I am getting good satellite and HDOP but the GPS never transitions from flashing blue to green with the ekf2_outdoor_gps_baro params. it is causing the platform to not allow me to put it in POSCTL. I do not intend to do GPS denied flights at this time and am trying to focus on outdoor 5G flights for a while to build confidence in our GCS software interactions with VOXL.

## Reply by Eric Katzfey (ModalAI staff) · 2023-04-27 15:20:28 UTC (in reply to JustinDev23)

@JustinDev23 These parameter settings won't affect the ability of the GPS receiver to get a lock. It is an independent unit and not affected by VIO in any way.

## Reply by JustinDev23 · 2023-04-27 15:31:02 UTC (in reply to Eric Katzfey)

@Eric-Katzfey, thanks for the response and clarifying.

I had a 3D Fix but wasnt able to switch from Manual to Position.  I have worked on other projects with Ardupilot mission planner and it could blend or use best from different sources.  I wasnt sure exactly how your implementation of GPS and VIO were working together on feeding positional data to the PX4 autopilot.

## Reply by Andre Moura · 2023-04-27 15:36:41 UTC (in reply to JustinDev23)

@JustinDev23 You can have GPS fix and not have GPS lock on the PX4. Have you checked the number of satellites on QGC? From my experience, GPS lock (required to switch to Position mode) is achieved with 12 satellites or more.
Maybe test the drone on a new location with more open space, that did the trick for me.

## Reply by JustinDev23 · 2023-04-27 17:10:04 UTC (in reply to Andre Moura)

@Andre-Moura sat and hdop have not been an issue on QGC. ekf2_req_nsats is set to 6 and i have had no obstructions and in open space.

GPS Horizontal Pos Error too high with 9 sats and 1.4 hdop

## Reply by JustinDev23 · 2023-04-27 17:19:58 UTC (in reply to JustinDev23)

And if it is not that it is GPS Speed Accuracy too low

I would hate to disable those checks but i feel like it is something else that is causing this to occur. 

@Eric-Katzfey Is there a flow chart for what all is feeding position information to PX4 from VOXL2?

@JustinDev23 This is the closest to what you're looking for: https://docs.modalai.com/voxl-px4-developer-guide/

@Eric-Katzfey I have the same issue. I tried the method that you mentioned, not only voxl-px4 is not working now, but also I got this error:

@Captain-7th Are you saying that the GPS is not working? I don't see anything in the included logs to indicate that GPS is not working.

@Eric-Katzfey Dear Eric, 

The log shows that the voxl-px4 is does not get completed and it crashes after a while:

```
what are these errors? after these messages, I couldn't run again the voxl-px4 again! so I decided the follow this way:

After reading some posts, I decided to upgrade the SDK version to the latest. I tried to upgrade the SDK from 1.0.0 to 1.3.0. Then running "apt update && apt upgrade" 

Then, followed some hints from you that you mentioned in some other post. I found the /usr/bin/voxl-px4-start file and added these commands at the end of the file:

1. qshell gps stop
2. /bin/sleep 1
3. qshell gps start -b 9600

Then, in my browser (HTTP://ip.address), it shows 255 satellites, but the GPS is still blinking in red color (should it be blue color?) Also, I checked the QGS app, it does not show the number of satellites and the drone location on the map. (I am in an indoor env, but I put the drone very close to the open window.)

@Captain-7th The connection to ground station has nothing to do with GPS. That is probably something related to your wireless network link. So I still don't see why you think GPS wasn't working.

## Reply by Captain 7th · 2024-07-02 17:50:11 UTC (in reply to Eric Katzfey)

@Eric-Katzfey Could you please tell me when the GPS is working, should it start blinking blue or red? Currently, mine is red! Please also let me know how I can check my GPS is working properly or not.

@Captain-7th That LED is a general PX4 status LED. If it is red it could indicate any number of different problems. It is not specifically tied to the GPS.

@Eric-Katzfey Thanks for the reply. Can you guide me on how can I check what are the problems?

Also, I have a wifi problem. Can you help me with that? My question is here: https://forum.modalai.com/topic/3600/how-to-set-up-the-voxl-wifi-station-mode-for-hidden-networks?_=1719998452051

@Captain-7th Please check the new forum post where you ask all these questions again.
