Hy all DIY UAV Builders ,
I would need your Help about APM2.0.18 / FW AC3.1.5
( First of all : I searched all around the forums to get the REAL response , and not only the same boring answer like :" look at the documentation " but allways fall on useless answer ( useless because I tested them and this doesn't works at all ) , I know the documentation as well because it's my Bible , so if you plan to answer like this you can go sleeping you won't be usefull for the comunity and obviousely for me :) )
Ref :
- APM 2.6 Board + NEO6M + POWER Cable.
- Mission Planner 1.3.31 ( just upgraded )
- APM Planner 2 ( 2.0.18 Just Upgraded )
- Arducopter 3.1.5 Firmware
What is the Problem :
I build my 3rd QuadCopter ,and get back my APM 2.6 to mount on => OK
Flew One Lipo => OK
Wanted to Download the logs for analyze after the flight ,I went immediately into APM 2.0.18 , and ... No Log at all ...
As I 'm a little paranoid , I decided to upgrade and use Mission Planner 1.3.31 , from the log tabs , clic on DL via Mavlink => KO , error messages "error while getting log list" ... no way I decided to open the CLI then Download logs ... and tadaaaa logs are here ... I donload them , and can analize ...
What is changed between my old Quadcopter and this one :
Only the frame !!! all electronic worked perfectly on previous build ... and APM from 2.0.17 to 2.0.18 (LINUX AND WINDOWS ) and Mission planner from 1.3.? ( don't remember ) to 1.3.31 ... allways working with AC 3.1.5 FW .
Questions :
1/ Why do I use the CLI to Download the Logs , while it is writtent to use MAVLink to do this instead ???
2/ Why do I use Mission Planner to do this , instead of APM2 ( cannot I only works on Linux and it worked as well before ... )
3/ Why This doesn't works with APM2 ??? ( Know ALL Bitmask and done at least 100 test
=> Setup the bitmask ,write to the board, refresh the list (OK ), disconnect the APM , PowerCycle it , fly indoor for 1 minute, power down the Quad and plug it to the computer => NO LOGS in APM2.0.18 , but in Mission Planner 1.3.31 only in the CLI ...
Anybody have some clues to fix this ( F.....G ) behaviour ???
Is there a simple checkup to know if my board is fried ?
Any thought , tip will helps My brand new Quad to works as he worked before ???
Best regards , and thanx to ALL Arducopter Team for their great Works :)
====================================
( sorry but now I'm boring and little hungry because every update of FW , or GUI makes too much problems I can't handle , I choose APM because this worked fine under Linux , like no other FC ( I only know APM ) , and just want to fly ( Video plateform essentialy ) I like electronic , Arduino , but for this project I can't spent time in debugging , cutting PCB track to fix somthing etc etc ... My goal when I purchased APM more than one year ago was to get the most reliable OPEN SOURCE FC)

upgrade your autopilot version, dataflash download over mavlink is a newer feature.
I just forget one detail , I tried 3.2.1 , but had too much problems with all GPS guided operations . And decided to downgrade to the last FW the Quad Flew .
I remember that this feature worrked as well , before up then donwgraded the FW , I intialized the EEPROM , with the Arduino IDE , did the job fine .
I managed to fly this afternoon , issue with Autotune ( didn't start ).and always the logs are accessable only via CLI .
It sounds like : backup parameters , test upgrade to the 3.2.x release , make the mandatory setup and try ... I will see if I still have same old GPS positioning defaults .
I follow your advise Michael , and upgrade to the 3.2.1 FW , I wish I won't have GPS issue with this FW as I had ...
I just kept all parameters from previous Compass / Radio / FS / Switches setup and will give a try this afternoon , and will come bcak to close this thread with results :)
Thanx .
Thanx mate :)
But I did it , and tried all AC from 3 to 3.1.5 , but still have this behaviour :
I cannot access to the logs , with APM 2.0.18 , I didn't downgrade the GUI to 2.0.17 ( the rev I used for some times and wich worked fine ).
I looked at the source code , tried to recompile the app ( under Linux ), but no changes ... this is why I posted here , I'm autonomous , I learn all by my self , I managed many many issues before .. but for now , I don't understand what could causes this behaviour ... and more and more I suspect the hardware ... it would be sad to "burn" a board while you get it back from a Quad to put it on another ... I never had this issue before ... I take care ( antistatic link to the ground of my desk etc etc )...
So if someone can tell me what I can test on the board to confirm it is defectuous , he's Welcome :)
For now I'm no confident enough to fly with my Quad ...
Is this correct ???
