thanks man

G'day JJBspark

Do you know how 'other' online sites (with a fee) can calculate wind speed during flight from the App txt file?
CsvView can (?) calculate wind speed from the .DAT file directly from Spark, but maybe not from the app. I do not know the value shown. (m/s, mph, kph, kt) but the .DAT file has a wind speed & direction column within flight records. After basic observation during flight, the records from CsvView & online seemed to be fair & indicated the observed wind conditions. Amazing what the logs contain!

Anyway, thanks for your programming skills.  Perfect for understanding the App logs!  Well done, very much appreciated.
Regards

Hi JB. I have tried  every version of FRAP and must admit that your coding is excellent. For a Freeware program I expect a few bugs so keep up the good work, you have helped a lot of people here.
With your own time (countless hours) for working to support the community I salute you

Hi Boffin,

Thank you for your kind words!

Minor bugs are always present in software.....but not too much i hope in FRAP.
Mostly bugs are in the interface, not in calculations.

G'day JJBspark

Hi Sparkz71,

Yes i know....well, think how you can calculate 'windspeed' from flightrecord data.

Put all data (groundspeed, move over ground direction, pitch+roll attitude drone, drone heading) in a calculation model and you will find windspeed. Pitch and roll data are crucial in this model.

To start you have to know the get-values for (in no wind situation) for moving fwd stick to pitch attitude down and corresponding forward speed. and so on....

If i have time i will try to make this algorithm.

Hi Boffin,

Thank you for your kind words!

JB, I once wrote a program to calculate the payout for horse racing in Z-80 assembly language (for a bookie). The complaint was that if a certain sequence of 3 keys were pressed simultaneously the program would crash. Now how many people would push 3 keys at once was beyond my comprehension so I modified the program to include a keyboard buffer.

Nothing is foolproof as fools are so ingenious

When using online log reader, no problem. However, when using your app, it can't read it, error message "illegal character" blabla.. I can't recall the whole thing but i'm sure you know what i refer to, other people had that issue.

Hi fofo18,

It should work if you don`t nest the maps/directory to far from the root.

Try for example this

x:\FRAP  [ 2 exe files, ini and jpg ]
x:\FRAP\flightrecords1 [for the flightrecord.txt files]
x:\FRAP\flightrecords2
x:\FRAP\flightrecords3

Did you find a solution for in google earth,  I cannot use basic kml, i get error gpx file not found???
Also is there a way to see which battery you are flying with?

Batt sn added to the main screen.

Basic kml error, looking into that (on my W10 pc no probs)

I have also w10 , do I have some microsoft visual C+ for your program needed

nope,

When the flightlog is converted a GPX file is made at the same time.
This GPX file has the same name, only the extension is GPX.
File to be found in the same directory as the flightrecord.txt.

GPX is changed into a KML file wich....oops   is not loading now at my PC.
Grrrr...my version is +1 than yours, and i did change this module..

will come back to you!

cheers

Oke, thanks (goed bezig)

JJB , many thanks, works now perfectly

Not many FRAP users do give feed back or wishes....
So really happy to have at least one person who comment on FRAP

Hi fofo18,

Hi, unfortunatly this is not the reason : my log file were already nested in a subfolder such as the one you mention. I tried to put in root folder of the app (and then they appear as soon as i launch it) but it's the same issue.

next trick, delete the converted CSV * file and reload the flightlog.txt file.
manual (file explorer) or via the menu in FRAP.

When does this error message pops up? can you make screenshot of this error?
FRAP works only with the DJI flightrecord.txt saved on the mobile device.
Txt files from other sources gives errors, if you like sent me the flightrecord wich gives this error.

It is of course a TXT from the mobile device (Android)! Sure, here's a screenshot about it.. And another showing the error message i get when opened last version, v4.4 (wether there is personal files or not in its -sub-folders).

Hello JJB, another question about color(orange) in the battery cells column, when becomes it orange? , just looks at my flight and saw that one of the battery show orange numbers in Sport mode and sometime on normal speed. (it was winter time, I have to look again)

Hiya,

Set at an arbritary value of 100mV..

Seen flights with > 100 mV with no mishaps, so do not really know what is the tricky value to throw away a battery...

Above 100 > just keep a good eye on it !

This is GREAT I cant wait to try it. Just need to spin up virtualbox and W10 on my mac

MANY thanks JJB for this work.

I seem to have the same issue as fofo18 with the error: File [ DJI..... ] not converted into CSV file ...
Is this problem resolved?

I would add that I'm trying to check the file generated on an android device, not on iOS. Might that be the problem?

Great program JJB ! Is there anyway to get the battery serial number from the logs ?

Thanks,

in the latest version : Edit / Batt serial numbers, |View  / Other data.

If your own serial numbers are entered, main screen bottom bar will show the info as well

Thank you Bob!

soon an update i hope (busy working at the code when i  have some free time)

Do you need to do anything to include the new Mini in your app? Was just a thought.

Hi Bob,  well....if you (or someone else) have a flightrecord from a Mini for me !?

No not off hand but i guess that would be what you would need. I am sure someone will soon enough when more people get their hands on them.
