However, when I go into config and tick the "alt correction" box ("alt set to zero when arming"). First the alt stays at zero, lift off -- two metres, three metres happy happy. Then I start to get horrid wrong values, 4500 metres, minus 196 metres. When I look at dashboard 1, the alt is all over the place. Other parameters seem sensible.

Without all correct, I have nice steady altitudes, even if they are offset with respect to the ground.

Thoughts, comments or is this an odd bug (I have the latest version)? Nobody else seems to have the problem.

I have looked through the code and maybe I found a potential bug causing this. I'm not sure. You have to test it. I'm going to release new version soon.

Hi.
If you use MultiWii version newer then 2.0 Ez-Gui should work just fine. You need to set up and connect your bluetooth module and you are ready to go. Only think you have to set up in the app is bluetooth MAC address in "Config".

Hi Bart!

First of all many many thanks for your great android app for multiwii !!!

It works amazing on my ASUS prime tab! I also have second one. It's Hyundai A7HD without BT. And I can't to download app from market (Google Play) accordingly. But I'm going to try to use it with 3DR modem. Will it work witout BT at all? I tried apk from this post viewtopic.php?f=8&t=2034&start=590#p36604 and have no success to connect just via 3DR. App tries to start both Serial FTDI and BT and then after pressing Connect no success.

Anyway it will be usefull for others and I would like to ask where it's possible to download latest apk file if possible and then get new upgrades? Could you make a constant share of apk where latest app will be always available?

Thanks in advance.
Alex

I started to think about new Dashboard. I want to display only the most needed information.
right now I have something like this:

It is just a sketch. Maybe you have some ideas. What to display and how to display it.
Looking forward to propositions.

Yes I know that
But when this is sent:
Code: Select all
requests = new int[] { MSP_STATUS, MSP_RAW_IMU, MSP_SERVO, MSP_MOTOR, MSP_RC, MSP_RAW_GPS, MSP_COMP_GPS, MSP_ALTITUDE, MSP_ATTITUDE, MSP_DEBUG };
sendRequestMSP(requestMSP(requests));
multiwii doesn't wait for all requests be received. It starts to send reply as soon as it receives ie. MSP_STATUS request. So the line is busy because more requests are coming and at the same time multiwii starts to respond to already received requests.
My Wireless Uart have two LEDs to indicator the sending and receiving.

With 1000ms setting in EZ-GUI and 9600bps, I can see clearly sending LED flash about 0.1s then receiving LED flash about 0.4s in 1s.cycle.

And every 10s, there is a short receiving LED ON about 0.2s. It should be the request for battery volts and something.

So I’m thinking they are ask/answer in groups.

There is a 200bytes buffer to cache all the data coming from Uart but not send out over air. If you are right, the buffer is taking a important role while the communication.

But buffer on the Wireless Uart may be not big enough to caching all the bytes multiwii send out.

Maybe I need Oscilloscope to see what happened on the line. But this equipment I can not get easily.

Hi
I optimized communication a little bit. It is still not perfect but it should be much better right now.
I have tested it at the baud rate = 2400 and works ok with refresh rate = 500

to use it you have to activate "New Request Method" in config.

Hi Ezio,

This is what im waiting for. Way point on MWI. I hope it also has not only way point (gps coordinate) but with : altitude distance (baro), facing to which direction (compass) and how long it stay, for each way point. Its like mikrokopter (MK) does.

Thanks,

John

the but is ... i am using tc's flightcontroller.
may take a while until i can process waypoints on my end.
nedd also a few enhancements for naze32.

Yes it has also voice and gesture control.... Lol:twisted:
Let's be a realistic. While multiwii doesn't have build in waypoint navigation the only think I can do it is moving the position hold.
For more we need to wait ...

Hi,

some people are writing about using EZGui with another baudrate than 115200. But even after reading through many pages of this thread, I can't figure out how to change the baudrate of EZGui.
I'd like to connect a BT-APC220-Bridge which is running at 19200bps.

changing baud rate is only possible when you are using USB (FTDI or other). For a Bluetooth the speed doesn't matter. When using Bluetooth you have to set the baudrate in the BT module.

Hi Bart,

I'm using your app to config my copter via bluetooth. Due to the limited
range I see no sense in your new map. Data from the copter will not receive
my mobile (5 to 7 meters).

And MWii doesn't support waypoints yet.

I'll test it when EOSBandi is ready with waypoints and there is a way to transmit
the GPS-Data over more then a few meters.

But it looks great

felixrising · Post by **felixrising** » Sun Jun 30, 2013 12:36 am

Hi Bart,

It looks good! Have you tested it with EOSBandi's WP stuff in r1448 / r1449? I haven't currently got a build with those changes in it, but do have a UHF Telemetry set that I've been meaning to put into action... thinking: Android Ph <-> BT <-> UHF 3DR Telemetry <-> Quad.

I notice that the (o) home in on me button (top right hand side) doesn't home unless there is a GPS lock. Is this home location the phone's location or the MW craft? Any chance of using the phone location service to give a ball park figure first, and then lock to GPS location? I ask because it's stuck in the South Atlantic Ocean whilst waiting for a lock.

EDIT: I've just looked back over the last few posts from you, including the redesigned GPS screen. I like the clean layout, but I think there are lots of useful informating being done away with. Can we keep the old screen and have option to use this one.. or maybe move the old screen to the second MW Settings tab or have a button to drill down to the old screen or something?

Two more things, can you add pAlarm (mAH consumed alarm threshold) to Dashboard 1 or to an appropriate screen under MW Settings tab? The other small request is would it be possible to add a "Link Pitch/Roll" to PID screen?

Love your work, hands down most useful app on the phone when a mw/baseflight/harakiri is in the air.

PS. If i buy your app on my HTC, will it then be possible to use this in my Samsung galaxy S3 with a larger screen ? (im using the HTC as a phone and the Samsung as a wireless device with a larger screen) Or do I have to buy it twice ?

ezio;

New waypoint stuff looks pretty cool.

We've been getting the summer rains here, so I am pretty much grounded, but if the weather situation allows, I'll be able to test before next weekend.

Even though Position hold and RTH are working pretty well on my Quad, I did not have the guts to set the transmitter down, and trust it to do stuff by itself, but now I am getting there, so I am at a good point to be a tester for this.

I'd be nice if there was a flight plan mode, where we could set waypoints with out the device having GPS lock, or being connected to the aircraft. Even if I un-check "Move Map", it won't let me manually just scroll to any place on the map.

Oh, and it would be nice if we could save multiple flight plans (i.e. sets of waypoints), and I want to..... and I want .... and .... Oh, sorry, I'm being a typical (l)user.

If you are using the same Google account on two devices it will work when you buy it only onece.

When waypoint navigation be supported by multiwii I will add more options. Right now I can only use what is available in version 2.2.

Just plug 3Dr in the Tab and connect.
Would it be possible to implement in MultiWii EZ-GUI?

Hi I am running MultiWii 2.2 on an AIOP V2 flight controller - Im using this BT module.

http://www.unmannedtechshop.co.uk/bluetooth-module.html

Everything works fine when i use a PC and connect to the Gui.

When I try to use EZ-GUI on my Samsung Galaxy S3 I can pair the BT OK but keep getting a serial error on EZ-GUI.

Has anyone else got this working on an S3 and could help me?

As I know (but never tested it) EZ-GUI works with 3Dr radio out of the box. you have to just switch to serial port in the config.

It seems it is working fine in current build. (including the one updated during I am flying today.) I am getting familiar with new icons. New map is very good with movemap and better layout.

I cannot reconnect BT once it lose connection. It started around the time EZ GUI started to report communication data loss. Once disconnected, BT gets into strange state and I cannot reconnect until rebooting Android. I am not sure what is the cause because I also upgraded my Galaxy Nexus to 4.2.2 around the same time.

New Waypoint map looks interesting but not fully tried yet, BT range is too short to try.

Thanks!

Hi Ezio,

Love your program and will register to show my support soon.
One thing i wanted to ask is if you are planning on adding more features (settings) from multiwiiconf.

Maybe after mw 2.3 is released ?

Examples:
pAlarm
mintrottle
vbatscale (and warning1, 2, crtitcal)
mag decl
and the new servo setting.

Should be OK right now. Also I updated the translation for those languages on Crodwin. If you want to add something please do it there.

A lot of the functionality is already implemented but hidden. Some time ago I wanted to stay up to date with dev versions but the things are changing to fast there. So now new functionality will be added after 2.3 release.

Try to put higher values for the refresh rate in the config. Or select new request method and then try different values for the refresh rate.
