MultiWii EZ-GUI

wilco1967 · Post by **wilco1967** » Sun Aug 04, 2013 12:30 pm

Perhaps not the right place to ask, but a lot of readers here might have the same question

I finally got an old android phone, and have succesfully used it with MultiWii EzGUI and a bluetooth link through Alexinparis's great UART radio project (433 MHz control + serial link with HK orange module).

Now I'm ready for the next step: Getting Frsky telemetry data (not MW serial data) to the android phone over BT. (mainly for my other planes).

I already have modified my 9X with Frsky telemetry, which is working great, using this mod:
http://openrcforums.com/wiki/index.php/File:Frsky_telemetry_mod_overview1.jpg
But I would like to try to have the same FrSky telemetry also available to EzGUI on the phone over BT

The question is: Could I simply connect the BT adapter in my 9X on the TTL side of the RS-232/TTL level shifter ? (in parallel to the Mosi / Miso wires) . I guess i might have to put some resistors to the lines somewhere....
I tried to find some schematic, but all I can find is the 9X telemetry conversion, and the bluetooth conversion, but not for both together....
I might go ahead and try, but I thought better ask first, before I destroy anything (which is working beautifully now).

Also I assume, I cannot have both the 9X and the bluetooth sending data out to the Tx module at the same time. I guess the only thing requiring sending anything is the adjustments of the alarms in the Frsky module.
For me it would be more than sufficient, if the android phone could only 'hear' the serial stream coming from the Frsky telemetry. I can do the settings from 9X. Is this possible, or MUST the android be able to sent in order to work ?

Thanks a lot !

I have tested the waypoints feature. Both with some random point and circular path.
The data link between Android and Copter is the 433Mhz Uart link.
There are working ok, thanks for your wonderful job.

When I set new holding point in “Map”, I must try 2-3 times that the holding point in MWC can be updated.

But in “waypoints map”, Do you have any retry mechanism ? Next holding points was updated very well.

This is correct. I get Telemetry both on my TH9X and over BT to ez-gui at the same time.

I had an interesting adventure with this fabulous tool, I did not read all 66 pages of this thread to see if anyone experienced this, but i was doing some PID tuning and at some point I must have restarted the exgui and not hit read, or something, i dont know, but i was making changes to my YAW rate and i saved to eeprom and tried to fly and it would suddenly just flip over.

I decided I must have given it a bad YAW rate setting so i went to put it back where it was, and i noticed that i somehow wiped all settings from the PID screen, except YAW rate.
it read zeroes across the board, and i had no save of the old settings, so i had to start completely over, lol.

anyway im flying again and ended up tuning it much better than before so it all worked out, but i wanted to share.

Yes, happened to me!
Before "writing" (changing), you need to force a "read".

Yes the same thing happened to me

Ez-GUI should always read PID settings after it first starts.

Hello everyone. Right now I'm on vacations so I can't make an update. If you can add every issue to on the github page. I will try to update ez-gui asap (September)

Hi,

I have a few issues with the Multiwii EZ-GUI that perhaps someone can help me with. My version seems to be the latest from July 15, 2013 in the Android Apps store.

First, this is my favorite Multiwii tablet app and a key reason for switching to Multiwii; being able to make field changes on an Android device.

1) Although I can get a map to display when I am in a WiFi hotspot, I cannot get a map to display without WiFi. Is this working as designed or is there a workaround?

2) When using the Waypoints Map, I can set up a circle and change the waypoints around the field. How do I activate the mission? I was expecting to see a flight mode that I could map to a radio switch setting or even a "Start Mission" button on the Waypoints Map screen.

3) My current link from the Android tablet app to my quad using Bluetooth, which is meant for short distance communication. Does the Waypoints Map screen download the GPS settings to the Multiwii board? Does this feature require a 3DR Radio Telemetry Link for longer distances?

Thank you.

Nickman1200 · Post by **Nickman1200** » Wed Aug 21, 2013 10:58 am

1) if you dont have any GSM/3G network data on your tablet you wont see any maps. EZ-GUI doesn't store any maps offline.

2,3) Multiwii hasn't got "real" way point / flight mission functions yet. I Think eiso made this to just move the home coordinate right now.
And you need to be in Bluetooth range for it to work.

Thank you.

HSPalm · Post by **HSPalm** » Thu Aug 29, 2013 1:57 pm

Yes as long as it functions like a regular Android tablet/phone and has bluetooth, yes. You need to have access to google play or download the .apk (android program file) for EZ-Gui from somewhere else.

If it has gps and bluetooth it should work. "Should" because sometimes people have problems with very low end devices due to strange memory management.

after yesterday update map stops to work because I forgot to change google map api key.
In the next update (in next 2 hours) it should work but I have made some changes in the code and I have no time to test it. so be careful when you use Set home position and set hold position.

tovrin · Post by **tovrin** » Mon Sep 09, 2013 8:05 pm

btw ezio, thank you for updating the PID setting, worked great for me! well, until i wanted to see what happens when i crank yaw rate up to .7 (matching my P&R rate) and i managed to crash my copter into the pool wall (thankfully, not in the pool, only cost me a prop)

wilco1967 · Post by **wilco1967** » Tue Sep 10, 2013 7:01 pm

Hi

I'm using EZgui with a bluetooth adapter for some time now, and its working great....

However, sometimes it is very difficult to get the BT module and my phone to connect. I many times get 'unable to connect'. Sometimes takes a few minutes and many tries with sometimes exiting EZGui as well as switching off the transmitter with BT moduel, and then suddely, it works

.... once connected, it stays on just fine. 8-)

Seems a lot like the issues I always seem to have getting Windows to connect to a BT device (ANY device)....... Might be just my bad luck with all kind of BT devices..

Are other people also having this issue, and is there a 'trick' to getting it to work more easily.

I tried 'new request methode' on and off, also changed refresh rate from 100 - 400, but it doesn't seem to make any difference.... very much doubt it has anything to do with EZgui.

I'm running the newest version (just updated yesterday, and it makes no difference). I use an old HTC desire S, updated to android 4.04.
Once it is connected, everything just works fine

Any Ideas ?

Wilco

tovrin · Post by **tovrin** » Tue Sep 10, 2013 8:05 pm

Wilco, i have this problem too, what i have found that works everytime, for me, is to immediately click disconnect (even if im not connected, obviously) and then click connect again.

everytime.

wilco1967 · Post by **wilco1967** » Tue Sep 10, 2013 8:58 pm

Hi Tovrin,

Thanks a lot for that tip....

That works beautifully

To clarify, for others having the same issue.

- Start MWgui,
- let it activate BT (if not active already)
- hit the android menu button, this will bring up the option Disconnect
- select disconnect
- directly after that, select MW connect from the top
- now it will connect without problems

justk1w1 · Post by **justk1w1** » Fri Sep 13, 2013 7:59 am

Ezio,

Firstly thanks for adding the debug codes into the graph list - they have helped heaps.

Just to add to the list of crashing problems, however I think this is more to do with the handling of the USB. I bought a On The Go USB cable and have tried to use the gui with a 3DR radio connected ( looking to get the extra range over the BT) and find that the application stops responding when using the device. I can get a stable connection using my Motorola Zoom (non rooted, but using the USB host controller app from Sztupy) using droidplanner for arducopter, but ez-gui seems to want to default to BT and then stops responding. I have tried setting it to use serial and other (cdc/acm). Is this correct for use with the 3DR radio??

Many Thanks
JK

Is there any way to enable disable some of the aux button features over 3dr or Bluetooth.

In essence could I hit a button on the waypoint or dashboard 3 page to enable GPS hold instead of using a switch or channel on Rx/tx. I only have a 6 channel remote and it would be cool to be able to tap the altimeter in your app or another button for alt hold or the attitude indicator for stable mode.

Right now it is not possible.
It is doable but I the application will have to refresh the status of the switch every sec.

It's much better to set new hold point. Thank you.

I strongly recommended you relocate the "Set home position" button. It was easily miss click when set new hold point.

And the home position is very important and should not be modified in most of cases.

Hello,
I discovered today MultiWii EZ-GUI. It's really fantastic to modify parameters from a tablet via BT. With graphics I detect a problem : when using in config/language/not force (for me French) only alt is displayed. When choosing English graphics runs well.

Is this knowed ?

I like this app! Makes tuning a MW board really easy.

Just one very trivial 'feature request' - would it be possible to have an option to turn off the voice that announces when you change to a new screen? It's not a problem in the field, but it does annoy my wife when I'm playing around and setting up a new machine for the first time. I've worked out how to turn off the periodic announcements, but I haven't seen anything to turn all the voices off. I know I could turn the volume down, but that would affect other apps!
