GPS not working
- 
					
					
					
					
 @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. 
- 
					
					
					
					
 @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.

 @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.

 @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.

 @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.

 @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 
- 
					
					
					
					
 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/

 @tom Thanks! Looks like what i needed.

 @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: INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained INFO [muorb] SLPI: Connection to ground station lost INFO [muorb] SLPI: GCS connection regained WARN [uORB] orb_advertise_multi: failed to set queue sizewhat 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: - qshell gps stop
- /bin/sleep 1
- 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.

 @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
