Does anyone else have this problem? Mission Planner connects just fine.. the artificial horizon moves with the apm, but sometimes it says "failed to update home location" and almost always gets stuck on "update params". After closing the "update params" window, the artifical horizon still reacts. While I try to view and refresh the parameters, there is nothing. Even when its "armed" the servos react to movement like it was on rtl, but they also react a little to radio from my receiver on the input side. Also, mission planner clearly reacts to my logitec controller graphically, but when enabled I can't control anything. Any ideas???

Hi Which controller are you using? apm? The hang on "update params" also happens to me( sometimes ) . I then need to re-connect. Which mode are u using? it sounds like you trying to move your ailerons / elevators while using Auto / rtl / Fly by wire etc... You need to put the controller in manual mode to get direct input from controller to your aircraft.

Greetings. I'm using APM (says v2.6.1 right on the board, also says 3DR(but that probably doesn't mean anything.)) Tried disconnecting and reconnecting many time, and update Params never happens. I now have full control with my Futaba radio but I can't get the gamepad to work. If my radio works, then shouldn't my Logitech gamepad work? Still haven't figured out how to get in manual mode, Is manual mode the ONLY mode Logitech gamepad will work in?

Hi GamePad will work in any modes. You can desire with mode you want in Mission planner, ( Mode Tab ). And then activate the game pad and calibrate buttons to any modes you want. Do you see any input from the controller in the joystick calibration page?

I can clearly see the input from the gamepad On the cadlibration page. I'm not sure how to calibrate the buttons to the mode I want.

Hello again. Well I got everything working..kind of... I installed an older version of Mission Planner (1.3.15) and when connected via usb cable, everything works perfectly(Parameters, joystick, everything.) When connecting UDP, parameters fail(always), and joystick doesn't ever work (even though it works graphically on the screen). Any ideas? I've also tried older firmwares, and that didn't help either.

Good afternoon I had this problem once, but i thought Michael Orborne had solved these isuess. Try install Beta version of MP.

Oh wow, you had exact same problem? I was beginning to think I was going crazy! I will try beta, thank you again.

Oh wow, you had exact same problem? I was beginning to think I was going crazy! I will try beta, thank you again.ya yeah, or very simular.. my problem then was it starts to receive packages and then stopped. But i know Orborne made a fix back then. You are using RPI with the TTL adapter, right?. On your local network? I belive you have checked correct ports and so on? Note! This line MUST have the 0.0.0.0 /root/udp_redirect 0.0.0.0 14550 $ip 14550 & if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); }

Also verify that TTL adpater shares ground with RPI.

Thx for the video, it says more than thousand words..
I belive the APM 2.6 does have internal compass which could couse you some problem.

See this thread

The external GPS unit has a compass built in. The APM 2.5 also has an internal compass (which must be disabled), and the external compass/magnetometer enabled in the GPS unit. Also, you have to cut the trace on the APM 2.5 board to enable the external compass.
In summary, if you get a error message "FAILED TO UPDATE HOME LOCATION" do the proper steps to make sure the external GPS/Compass is in use. It ended up having nothing to do with the radio.

If you disconnect the GPS/Compass unit, would that make any difference?

This revision of the board has no onboard compass
I'm still going to try disconnecting compass and GPS, just to see what happens.

Sinamics

If you select the Mavlink Message Debug option under Config/tuning Tab in mission planner, you may be able to see whats going on in the code. just a thought..

Sinamics

If you open the Documentation for APM2.6 is listed with HMC5883L-TR, 3-Axis Digital Compass.
APM 2.6 Autopilot

EDIT #1

This revision of the board has no onboard compass, which is designed for vehicles (especially multicopters and rovers) where the compass should be placed as far from power and motor sources as possible to avoid magnetic interference. APM 2.6 is designed to be used with the 3DR uBlox GPS with Compass (see option below), so that the GPS/Compass unit can be mounted further from noise sources.

Understood. hehehe

Hello again.

Well, this just gets stranger and stranger. I completely disconnected my ublox gps and mag. THERE HAS TO BE AN ONBOARD COMPASS, it reliably reacts to movement, and is not that far off??? Also I received my USR-TCP232-T module and got the software you recommended (USR-TCP232-setup) to work. Result: Same exact reactions over local network, with or without ublox hooked up, except apm had red light without hooked up. Did 3DR screw up, either in documentation or hardware? MP identifies it as Arduino Mega 2560. Does this sound correct? Also, would there be any possibility of hooking micro usb to ethernet to RPI? Things seem to work better though the usb than the telemetry wires.

Sinamics

MP identifies it as Arduino Mega 2560. Does this sound correct?

The APM board is in fact build on Arduino 2560, so i guess this is normal.
You can also successfully download the APM software to Ardunio 2560 board.

would there be any possibility of hooking micro usb to ethernet to RPI?

I guess it would be possible with a converter of some kind, but im not sure.

Your problems seems very strange..
I will try to hook up my APM board with the same setup as you using, and see if i get the same problem as you.
Maybe today or tomorrow..
It could be related to Mission Planner serial package or something simular.

Chuckster1

Thank you much. I hope you get the same problem.lol...Still, 3dr is messed up...documentation DOES NOT match hardware in my case...I'm going to call them...they definitely screwed up

Chuckster1

Hi.

Well, i was able to install APM planner 2.0, and I got the beta update on MP. I have the same results on the clone and on geniune 3dr stuff. It will be interested to see if you get the same result, and if so if you can figure it out. Did you use this setup on a pixhawk? I'm prob going to order a Pixhawk, looks like the best flight controller anyway.:-)

Sinamics

I cant find my APM at the moment, but i will hook up my pixhawk and install latest firmware and so on,..
If that works fine, i will try to locate my APM and re-prodcue the same issue as you.

I received my "fake"pixhawk today and new TTL adapter from china, so if that works fine, it should definitely works on yours also.
Yes i used this setup on my old Pixhawk. No problems at all.

Give me couple of hrs, and i will revert back with the result

Sinamics

I will have to test this tomorrow, as i need to create some new cables.
Stay tuned.. hehe

Chuckster1

Awesome, thanx again.

Sinamics

I have now tested and it works like a charm. Tested using 4G.

Equpment:

Pixhawk (Fake) with Arducopter 3.2.1
TTL to Eth adapter.
RPI 2 with latest Wheezy img
Release version of Mission Planner v 1.3.19
USB modem ZTE MF821D using UQMI as connection software.

image 141208626055034e7772063693019499.gif

All powered from 4s Lipo with step down to 5v.
Connected in a hurry.. hehe quite messy

image 1217456041550350e705ecf618218157.jpeg

So i think i need to search for my old APM board, and reproduce same settings as you.

Chuckster1

Hi.

Well, thank you for showing this. I ordered a pixhawk and am looking forward to this setup. As for the APM, I think I'm getting closer to solving this problem. I can pull my RX wire from the APM (the one that goes to TTL converter TXD) and I have the EXACT same problem. Everything will run the same as my video, with only the APM TX wire conncected, and the APM RX not connected to anything. I have 3dr 433 Mhz radios, so I know there is not a problem with APM internally with the RX. The 5th telemetry wire bothers me. I have begun the internet search for the function of this extra wire.

Also, I "fooled" mission planner a little bit. I went to initial setup wizzard and tried to make it connect UDP. Instead of getting a blank "updating params" it got stuck on "sysid1 compid 1". Upon googling this, I came across an interesting post from Michael Oborne, dated April 23, 2014 ."you are only getting traffic one way. MP required 2 way traffic. check your wiring."

http://diydrones.com/group/arducopterusergroup/forum/topics/mavlink-failed-getting-param-sysid1-compid1-and-then-nothing?xg_source=activity

Also, I found this, but not sure what they are suggesting with an OSD.

Thanks for reading. Weather is getting nicer, and I plan on doing a lot of flying this summer. :-)

Hello

Well, I received my Pixhawk and still have the same parameters problem. Just wanted to verify a couple of things.

My UART module is receiving 3.3V from RPI GPIO.
My RPI is receiving power through a spliced microUSB.(Red and black(white and green wires not used)) This 5v comes from a 5V 5amp SBEC, which is powered by a lipo.
Pixhawk is powered through the 3dr power module.
Pixhawk ground connected to serial converter ground, and RPI ground
I only flashed the firmware, and did not perform any calibrations or initial setup (usb doesn't care, it still gets params)
I'm running MP on windows 7 pro 64 bit

Any ideas left?
Any help or idea is much appreciated...

Hi Chuckster

This is quite strange...

My UART module is receiving 3.3V from RPI GPIO.

Im using 5v power supply to VDD pin.

My RPI is receiving power through a spliced microUSB.(Red and black(white and green wires not used)) This 5v comes from a 5V 5amp SBEC, which is powered by a lipo.

I also power the RPI from USB cable while testing... no problem. This should be fine.

Pixhawk is powered through the 3dr power module.

Same as me.

Pixhawk ground connected to serial converter ground, and RPI ground

During last test i was using same power Source for Pixhawk and UART module. RPI was powered from USB..

I only flashed the firmware, and did not perform any calibrations or initial setup (usb doesn't care, it still gets params)

This should be ok..

I'm running MP on windows 7 pro 64 bit

Me 2

Here is a Wireshark screenshot of what's going on.

Laptop:192.168.1.233
RPI: 192.168.1.3
Edimaxte_xxxx: wifi adapter in rpi
Uart module :192.168.1.120

Kind of says the same thing as MP link stats: A whole lot of download and not much upload...Maybe someone can analyize this.

Sinamics

Im not an expert in Wireshark and analyzing that data..
Here are some (probably dumb) questions. 🙂

have you tried another Ethernet cable between RPI and UART modul?
Could you post a picture of your UART modul configuration? Did you set the gateway ect ?
You could try to stream data to my computer in Norway if you want.. See if anything is wrong in your laptop. (Send me a PM)

It has to be some basic part missing or something in your wifi part blocking that data..

Chuckster1

I tried another ethernet cable. Here is my module settings. Also tried matching gateway to destination IP like your picture.

RPI=192.168.1.3
Laptop=192.168.1.233
Module=192.168.1.120

Thanks again.

Dear all,
In these days I was setting up my new drone and I had more or less the same issue: the connection with mission planner was working properly in my home lan, but when I tried to do it with cellular lines, the connection stopped exactly while "getting parameters". Luckily I found the reason of the problem: I was streaming the output ov mavproxy to the dynamic dns xxxxxx.no-ip.info and this was creating some trouble, if I use directly the ip number, everything works properly.
I hope this can help somebody. Do you have any idea why noip creates this problem?
