Thank you for your interest in our Intel products.
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:
I would suggest you re-flash the latest firmware version and make sure the BIOS, FPGA and Flight Controller are updated as well to the latest version: https://downloadcenter.intel.com/product/97178/Intel-Aero-Compute-Board
Hope this helps.
You actually just helped me out on the accelerometer problem haha
Thanks for that!
I reflashed the firmware an awful lot of times in order to solve that problem so I guess I have all the latest configs:
BIOS_VERSION = Aero-01.00.13
OS_VERSION = Poky Aero (Intel Aero linux distro) v1.6.1 (pyro)
AIRMAP_VERSION = 1.8
FPGA_VERSION = 0xc2
Aero FC Firmware Version = 3.5.3
We did not test it out-of-the-box, so I wouldn't be able to answer that one. When we received it, we went straight to a manual flight test, in which we DID notice the drone was tilted when flying and would not respond to neither RTL or pos hold. Nevertheless, we continued trying to calibrate it via controller trims and eventually crashed the drone.
Is there any way to test antenna integrity? I'm quite sure both connections and antenna position are ok.
You can quickly check if GPS coordinates are received by FC.
SSH to Aero shell.
Copy the mavlink_shell.py to /home/root
a. You can find mavlink_shell.py here at https://github.com/PX4/Firmware/tree/master/Tools
Then login into FC shell( nsh>) using the following command
a. ./mavlink_shell.py 0.0.0.0:14550
Run the FC shell command: listener vehicle_gps_position
It will show lat: lon: and other GPS parameters like hdop, vdop..etc.
Just ran the command and got this results:
nsh> listener vehicle_gps_position
TOPIC: vehicle_gps_position instance 0 # 1
Since the compass was calibrated it means the GPS should be connected. Please try to restart the GPS in the shell command line using these commands:
Then run the command "gps status" and please provide us with the output of this command.
Also, please check if other gps devices are able to obtain signal at your location.
This is the output, runned it twice just be sure. About GPS signal, my cellphone was able to detect about 7-8 satellites but the drone detected none...
Are you having the same issue in Ardupilot? I know you said it worked normally there on the other thread. Is that the same case here or are you also having GPS issue in Ardupilot?
Actually, yes... same problem.
I was trying to solve one problem at a time so at the time I thought I wasn't get any signal because I was indoors, but further testing showed me it was some kinda problem with the GPS itself
There must be something wrong with the GPS module itself. I would suggest you purchase a replacement.
