I just got off the phone with 3DR today and 3DR confirmed a known telemetry bug in Mission planner today. This is the issue I told them I am having.

First off I would like to clarify a few things.

 My testing included two computers.

1st PC is a Panasonic tough-book running XP pro.

2nd PC is a Asus   running Widows 7 PROFESSIONAL.

First and foremost both PC's have a fresh copy of there operating system installed and updated and then I re-installed MP from the Website. 

This is what happens.

Test #1

Connected Pixhawk to MP using USB cable and planned out simple 12 way-point mission. The mission included,,  take off,, way-points, , region of interest, ,, and finally RTH..

Wrote the mission to PH and then read it back several times in a row and it is flawless as it should be.

Nothing at all changed and again it reads  back perfectly as it should using USB.

-------------------------------------------------------------------------------------------------------------------------------------

Test #2

Now with that mission still in the PH.

I unplugged the USB connection and regained connection using 3DR telemetry radios. 

I read back the mission several times and every time i read it back something changed. I ended up with two (take off) lines of commands and my RTH disappeared completely and never came back and my ROI command would Change command lines.

Now I unplugged the 3DR radios and again plugged in the USB connection. I again connected MP to PH to see if the mission was that messed up.

When I read back the planned mission using the USB connection everything was normal and it was the original mission to the T. and my RTH command line returned also.

-----------------------------------------------------------------------------------------------------------------------------------

 Test #3

Well hold on if you think it is a 3DR radio issue. .

So next, I installed APM planner 2.0 on my Windows 7 Pro PC,  and my XP PC.

Since APM and MP are a little different as to the features  I deleted the existing mission from Pixhawk and setup another mission in APM 2.0. 

I planned a mission in APM 2.0 and written it to PH using USB connection.  

I then read it back several times and again I had ""ZERO"" issues it was perfect every time using the USB connection, Just as it was with MP.

(((Are you ready for this)))

So I again regained connection with PH using the 3DR radios and read back the mission several times. the outcome ((( It was perfect and flawless using APM 2.0. )))

So it's not a 3DR telemetry radio issue. 

-------------------------------------------------------------------------------------------------------------------------------------

Test#4

Hold on ,,,I'm not finished yet. 

So I disconnected and closed out of APM 2.0. 

I Opened MP and connected to the Pixhawk using the 3DR radios.  I read back the mission and found that it again had changed the mission command lines. .

If I read back the mission three times or so it will eventually read right..

So there is a bug. Not with the 3DR radio link but with mission planner.

------------------------------------------------------------------------------------------------------------------------------------

Test #5

So is it the PC running Windows 7 Professional with a fresh install? Let's find out. 

So I did the same test with a different PC, I used the Panasonic tough book running a fresh copy of windows XP and a fresh download of MP. .

I had the same outcome with the same test every time as I did with the Windows 7 operating system  

So It's not the PC'S nor is it the 3DR TELEMETRY RADIOS. 

There is something missing in the transmitted and received packets.

But what. .. 

--------------------------------------------------------------------------------------------------------------------------------

Test #6

I planned out a large mission and wrote the mission to the PH using the 3DR telemetry radio. Once written I disconnect the telemetry radios and read the mission back using USB connection.

I found that writing the mission to the PH with the telemetry radios works fine but again reading it back using the telemetry radios is a disaster. Once again I connected the USB and read back the mission and it was just fine.

--------------------------------------------------------------------------------------------------------------------------------------

SO this is what I know,

Two different PC'S running two different operating systems and the same programs and having the same issue with that program(( MP )).

Found NO read or write issues using telemetry radios with APM planner on either XP or Win 7 PC's

I wanted to run the same test using Droid planner and MP but I had found that Droid planner and Mission planner Don't play well together. I had found that some of the flight modes are not recognized from one to the other so there could be no testing done..

SO there you have it.

Why does this happen in Mission Planner and NOT in APM planner? whats missing?

What is the fix for this?

 Michael Oborne If you are reading this could you please help.

  • Sill no answer to this issue.

    Is there a bug in Mission Planner.

    • Bro even the Mission Planner is updated but i don't find any type of bug bro :(

  • Ok this is what I have seen in my testing. 

    I have a old Panasonic tough book running XP Professional with service pack 3.

    I have a newer laptop ( 1.5 years old ) Asus  running windows 7 Professional.  I have both mission planner and APM planner on both computer's.

     When I (WRITE) a mission to the Pixhawk using Mission Planner 1.3.10 and then (READ) the mission back to verify the mission waypoints the waypoints and settings change from what I had originally written.

    This happens using either PC.

    Now when I (WRITE) a mission to the Pixhawk using APM Planner 2.0.14 and (READ) the mission back it reads the same as it did when I originally wrote it. It is perfect

    And again it works perfectly in both computer's.  So I don't believe it to be a  .DLL issue. 

    Also on the Panasonic running XP Professional I re-installed the operating system just so I had a fresh copy on board.

    So the question is, WHY? 

     

    • Well this weekend I'm starting over. I will Uninstall mission planner and all is folders on one PC and start with a fresh download.
      Then I am going to reload everything on the other PC after I install a fresh copy of XP and see if there is any good news. ..

      I will keep you updated. Thanks
      • Ok bro Keep Posting I'am waiting fo your reply bro :) do it and install the previous version of mission planner :)

        • yuvraj

          I found something very interesting, but before I tell you I need to ask you if you are using the 3DR telemetry radios? If you are, are you writing your missions over the radio link or are you plugged directly into your flight controller. 

          Also are you using a Pixhawk flight controller? Thanks

          • Yes bro I'am using the Pixhawk FC only and I'am writting the mission through a 3DR radio only not by wire , what's the interesting thing you got bro ? Is the problem solved ? 

            • Nope problem not solved, ,

              On my PC running Widows 7 PROFESSIONAL. I completely removed anything and everything related to mission planner and also APM PLANNER 2.0  including folders and then I re-installed MP only from the Website. 

              This is what I have found,

              Connected Pixhawk to MP using USB and planned out simple 12 waypoint mission. The mission included,,  take off,, waypoints, , region of interest, ,, and finally RTH..

              Wrote the mission to PH and then read it back several times in a row and it was flawless

              Nothing at all changed and again it read it back perfectly as it should using USB. 

              Now with that mission still in the PH I unplugged the USB connection and regained connection using 3DR telemetry radios. 

              I read back the mission several times and every other time something changed. I ended up with two (take off) lines of commands and my RTH disappeared completely and never came back and my ROI command would Change command lines.

              So now I unplugged the 3DR radios and again plugged in the USB connection. I again connected MP to PH to see if the mission was that messed up.

              When I read back the planned mission everything was normal and it was the original mission and my RTH returned also.

                Crazy right? 

              Well hold on if you think it is a 3DR radio issue. .

              So next, I installed APM planner 2.0 on my Windows 7 Pro PC,  

              Since APM and MP are a little different as to the features  I deleted the existing mission from Pixhawk and setup another mission in APM 2.0. 

              I planned a mission in APM 2.0 and written it to PH using USB connection.  

              I then read it back several times and again I had zero issues it was perfect every time using the USB connection, Just as it was with MP.

              (((Are you ready for this)))

              So I again regained connection with PH using the 3DR radios and read back the mission several times. .

              ((( It was perfect and flawless using APM 2.0. )))

              So it's not a 3DR telemetry radio issue. 

              Hold on ,,,

              I'm not finished yet. 

              So I disconnected and closed out of APM 2.0. 

              I Opened MP and connected to the Pixhawk using the 3DR radios.  I read back the mission and found that it again had changed the mission command lines. .

              If I read back the mission three times or so it will eventually read right..

              There is something missing in the transmitted and received packets.

              But what. .. 

              The next set of testing will be to plan a large mission and write the mission to the PH using the 3DR telemetry radio. Once written I am going to disconnect the telemetry radios and read the mission back using USB.

              I figure this would narrow it down to transmit or receive side of things. 

              I hope someone has had or seen this issue also.

              Two different PC'S running the same programs and having the same issue with the same program. 

              Ghost in the machine. 

              Help

              • sorry for the delay bro , Bro I'am totally confused But I will try my level best to sort out this issue give me 1 or 2 day let me get the solution for you bro :)

                Happy Flying :)

                and watch my video bro it's not clear but still it's good to watch and see response of this copter ......and reply me is this good or not ?  here the video

                Yuvraj

    • Ok bro have you tried with the previous Mission Planner software if you tried leave it if not please install the previous version of Mission Planner and you can get to know whether it is bug or not but in mine I don't feel there is an bug because I'am using it right-now

      before Installing previous Firmware you have to uninstall the current MP as well you have to remove the backup file in the program file of your windows system :)

      Let me know bro :)

      Yuvraj (Happy Flying :))
