Solo Pixhawk External USBPort

[Orin]

Has anyone developed a external USB port that would allow download of the flight logs? Why 3DR didn't include this is strange and having to use a program like WinSCP is a PITA in MHO.

I did read somewhere that you could email yourself a "troubble ticket" but I haven't found a way to do this.
Does anyone know how to do this?

Thanks,
Orin

Orin, 3DR removed the ability to email logs to ourselves.

USB is available via the accessory bay
Otherwise use WinSCP- it's about as easy as to connect an USB cable.
Both ways provide access to the last 10 logs for Pixhawk, Gimbal, Wifi, Tlog ...

Than's nuts - Are they going the way of DJI and keeping everything a big secret?

It would be nice if someone developed an accessory to bring the USB port out for those of us that don't want to mess around with WinSCP or a similar program.

I thought they changed the location of the dataflash logs to the on board computer???

As frustrating as it may seem to some users, in my opinion I think having a USB accessory just for logs is unnecessary. If the user is willing and capable of looking at flight logs, using the solo cli or any million other ways to download the logs through SSH is actually really easy. I prefer a wireless method any day so long as the speed is decent which it is through SSH. You even get the benefit of encryption without having to worry about it.

It's not a big secret, rather, you're just not as comfortable with the current methods yet. You can easily use your phone to download the logs instead. I do it all the time.

Seems odd to me - for someone capable to analyze log files in MP it should be a no brainier to work with WinSCP or even CLI.

Would you post a link to where "Solo Cli" is?

I have looked on the 3DR site and searched for "CLI" and "Solo CLI" and there wasn't any results. I did find a service manual which I didn't know existed. Maybe there is a discussion regarding "CLI" in there.

What I find frustrating is the connection goes to crap after about 10 minutes. You need to turn it on, connect by WinSCP right away, and begin downloading immediately. If you wait too long, it will not connect and you have to start over. Also, if connect via Mission Planner, the packet loss is almost 95%. It's a miracle it works at all. These annoyances make we want an old fashioned cable since it is 100% reliable, and can power the device.

When did getting logs via mission planner break exactly? This used to be possible but very slow but anytime I try to pull logs in from MP all I get is gimbal clicking and MP hanging to the point of having to be killed.

Click the LINK STATS button up at the top right near the connect button in MP. You'll notice the connection quality is like 4% and packet loss is almost total. It's not a problem with the log download. It's a problem with MP's connection to solo.

I find that using a site's built-in search in general is useless so Google would be better in most cases.

Alternatively, if you want to use an app or FileZilla or any number of other tools to grab the logs, let me know and I'll be happy to point you in the right direction.


Regarding the disconnects that some mention, it sounds like an SSH idle option. That can be disabled actually from the client side usually.

Solo CLT is an awesome little ditty
3DR has stated that in the future they were going to make logs easier to get through via the app

USB is faster download. Sometimes it can take me 20+mins over WiFi if I have lots of logs to download.

 

[pyrate]

Not on CLT

 

[SurfnSkate81]

@pyrate I had better find the time to get up to speed using CLT then.

One possible cause as to why it may take a long time is because there are symbolic links that point to the same logs which get followed and it goes on in a cycle. This was a quick glance that I noticed when I downloaded the logs through rsync so I could be wrong.

No, it's because internally (when using MP) it is connecting to the computer, which is then connecting to the pixhawk over a slow internal connection (9600 baud I think I read?). USB bypasses that process. The CLI is the fastest way to retrieve logs. It takes seconds to DL several MB large logs when it would take MP 5 minutes to do that, and then the connection gets hosed and you have to repeat many times. With CLI you can retrieve them all at once, and at very high speeds. Also, 3DR recently added a feature so the BIN logs are in the /logs dir now too, so it's even faster. MP doesn't know to look there - it pulls them straight off pixhawk.

Aahhh that explains a lot! Thanks! I haven't gotten around to using MP yet but this is good info to know.

What would really be nice would be for 3DR to reactivate the ability for a user to email themselves a support ticket which would have the logs attached just like a ticket to 3DR does now. Maddog mentioned that this used to be possible but 3DR deactivated this feature from the Solo APP.
