It's hard to know which the root cause of the issue might be. Could you provide some additional information so that I can provide you a better assistance? Please let us know the following:
We'll be waiting for your response.
Have a nice day.
Good day! Of course.
1. For now i have used last firmware version 1.5.1
2. Yes, i have tested outdoors, but there is no signal gps. Firmware version before 1.5.1 was less 1.2 and gps from out-box was worked.
3. For now antenna is raise up, i have check connection. If i disconnect gps from drone, i will have more problems in Qgroundcontrol, something like cant find external compass or something else. I suppose its mean there is normal connection with gps module.
Maybe there are some methods how i can to test gps or some additional properties?
How much time gps need for lock? because i use drone in Ukraine, maybe gps need much time to connect to satellite.
Maybe its problem with firmware?
Thank you for the information provided.
I haven't had this issue before. It could be due to a problem with the firmware, but honestly, I'm not sure what the root cause of this issue might be. Please let me investigate about this, and as soon as I have new information I will post it in the thread.
Just to double check, did you update the BIOS, FPGA and Flight Controller as well? This new software release requires to have them updated.The guide to update them is available here: https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-Setup# flashing-the-bios 02 Initial Setup · intel-aero/meta-intel-aero Wiki · GitHub . I'd recommend you to re-flash the Aero and the BIOS, FPGA and Flight Controller one more time just to be sure that everything is properly set. Anyhow, I'll keep investigating about this issue so I can provide you a better assistance.
I re-flashed the latest firmware (1.5.1) and I was able to verify that GPS lock works with this version, so the issue is not related to the firmware.
My recommendation, as I mentioned previously, is to re-flash the latest firmware version and make sure the BIOS, FPGA and Flight Controller are updated as well to the latest version.
Have a nice day.
Thanks for the valuable info you've provided here.
I'm a new PX4 user and I'm facing exactly the same problem.
Please let me know that how to check/update BIOS, FPGA and Flight Controller as you've described above?
