I did have done everything as described in that guide. Uploaded new firmware.
But the guide does not say exsactly how to connect wifi module to MultiWii (should I just use board's UART serial tx -> rx, rx -> tx? or serial which i use for FTDI?), and nothing about how to use that firmware. I tried to send "AT" command through FTDI, no response.
And although, in my case the wifi module asks me for password. What is the password?

my esp8266 when booted send this string at 115200:

If I change baud rate to 74880, it sends this:

How can it possibly be? Shouldn't it work on one baud rate?
How to fix this?

Just wondering what you're flying

I have switched to cleanflight.

Hi, I run Cleanflight and connects to EZ GUI via bluetooth on a softserial port at 19200 baud. It works, but there is a bug, or maybe a feature in Cleanflight that makes it hang if there are to high data rate on the softserial channels. This happens very easy if there also is a GPS at the second softserial port. Now this is a Cleanflight bug, but it seems to be hard to solve it. The bug has been around for many versions of Cleanflight.

A workaround to make EZ GUI to work in this setup would be if it somehow was possible to reduce the data rate on the serial channel that EZ GUI requests data from the flight controller at MSP.

Could this be done?

Amount of data being transmitted has been significantly reduced in version 3.5 and 3.6 of ez-gui. You can set also higher value for refresh rate in EZ-GUI settings. I usually use 250 but you can go eve higher.

I'm currently running 3.5.212

I've increased the refresh time to 1000ms and it works a bit better, but the problem is still there. Cleanflight hangs after a short while. Allmost immediately if you go to cleanflight settings. After a minuteif you stay in instrumentation.

I think that a delay is needed in between each byte rather than setting a high cyclic refresh time. My guess is that already after a short chunk of data in high rate there are some buffer in the Cleanflight Softserial implementation that overflows. An optional solution would be the possibility to set the bluetooth baud rate to a low value like 1200 baud to avoid overflow in Cleanflight.

I'm happy to try a beta if that is easier for you.

Thank you for supporting!

The minimum baud rate in CF is 9600, so you can't go lower. You may wish to consider either building from git master (or the nightly builds of pre-1.12); this provides LTM (Light Telemetry) that is fully supported by ezgui 3.6.125. Using pushed telemetry (vice polling) reduces the load on CF soft serial. LTM using softserial 9600 baud works flawlessly for me, albeit using mwp rather than ezgui (but tested as well on ezgui/softserial@9600). If you're serious about GPS / NAV on naze32 & clones, consider using the CF INAV fork. In addition to LTM, this offers much enhanced PH and RTH as well as autonomous WP navigation using a subset of the MW-nav protocol (and thus is also supported by mwp and ezgui).

Hi Ezio,
I just downloaded Version 3.6.216 and I can't figure out how to use the app. The former
config page is no longer available so I can't select which one of my 4 Blue tooth Quads to talk to.

I have the same problem. It doesn't matter if I have my phone upright or tilted. The dotes don't show up.

Thanks Patrike,
That did it. How is anyone supposed to know that is the new connect method. I wish there were
an ongoing manual or description of the features, they are not always obvious.

Probably you have the phone with physical menu button (a lot of Samsung devices). When device has this button three dots don't show up. Press button instead.

Is it possible to add an option to display your fpv image in the app? Right now I plan to use otg fpv input and display it via a Webcam app on my android screen. Would be awesome to combine the fpv image in the app. With all the telemetry and gps location.

Hi,
I followed this instruction, I have Multiwii CRUIS SE 2.5 board with MultiWii v2.4, ESP8266 wifi, android phone 5.0 with newest EZ-GUI installed. I can see sensor readings, but I cant control the drone via phone. The steering controls on android just don't work.
What am I doing wrong?

@ezio, there is a bug in the latest version, in mission planner. If you draw a mission path, and select last waypoint as LAND, the distance is not calculated correctly - the length of the last segment is missing. This can be serious problem, because someone might send the copter too far, fooled by wrong distance information from ez-gui. Can you check for this?

Ok, I managed to make in working, just needed to change mincheck value.
But here s another problem, EZ-GUI crashes occasionally when motors start spinning, and after crash motors spin at max speed.
Could anybody help?

I think there are a couple of bugs with the latest baseflight build from github repo.

The first is with the servo config tab. The servo info via the CLI 'servo' command is correct, but it appears corrupted when accessed via the servo window in ezgui. The values are all scrambled & incorrect for all servos after servo1.

EDIT:
trims seem to work fine now.
Here are pics of the output for the servo window vs. the correct servo settings from CLI...

So any plans to make ezgui work on a note5 via the wired otg connection method?

I've seen several reviews from note5 users who are having the same issue as me so I don't think it's just my phone?


Basically everything works great until I try to write changes to my fc, at that point my phone (note5 on Verizon) just reboots every single time. bt is not an option on most of my quads since they ar f1 fc's and I use satellites on all but one and I really hate haveing to carry my tablet around everywhere just to make a few changes.

it worked fine on my previous phone (note3)

Thx...I love the app but it's been several months and a couple of updates have occurred since then so I am beginning to wonder if this problem is even on the developers radar?

For all this months I was searching the cause of this problem. And I'm still not entity sure what's going on. It happens only on samsung devices with android 5.x
Probably I have a solution for it. It's being tested right now.

If you want to try it here is the link (don't forget update from google play when fixed version will be released):

Do you have baseflight selected in EZ-GUI settings? Servo tab shouldn't be available for baseflight as it is no longer compatible.
As everyone seems to switch to cleanflight, Baseflight support is no longer maintained.

Hi. Just don't use it to control you model. It is not reliable enough and sooner or later you will have "fly away".

This feature was added because it was possible, and for testing purposes.

Setting failsafe may help.
But again please DO NOT USE IT.

It is possible but it won't be done as there is very little demand.

For the record.. I have a Samsung Galaxy S5 with lollipop (5.0) on it, and have no trouble.

Thanks Ezio! I installed the apk and gave it a try and I was able to change some settings and save them to my fc for the first time using my note5+otg.

I did have the app freeze up on me initially but it may have been my phone... it seemed fine after I restarted my phone, made several more changes and saved them with no issues. I'll be using it more in the next few days as time permits so I'll report back if I run in to any issues.

btw, I didn't see a option to select betaflight in the controller choices like there was in the previous version, I selected cleanflight and it seems to work but just thought I would mention it.

Thanks for this info. I am about to test the "Land" option but will now wait until a EZ-GUI fix is released.

You can test it now. It will work as it should. Only displayed distance in EZ-GUI is wrong.

Hi ezio,
this is my first post, but i use your ground station since about 2 years...
in last version , in mission planner, if last WP is RTH, it's displayed on the map in the ocean, in front of "la cote d ivoire".....and the app shuts off...
what about it?
can you please verify and check?

cordialement

Frederic

PS: in previous version last WP ( if RTH ) was not displayed but the planner worked fine

Today I did my quick first tries with the autoland option in MultiWii.
The autoland function was activated via switch on the transmitter.
I wanted to make sure it works before setting it up on EZ-GUI.
The settings are stock and it seems to work good. I will have to check and see how I can tweak the settings for it to come down smoother.



PS: My new movie renderer is acting up....

Let me absolutetly confirm that CF INAV fork GPS functions work like a charm in naze32 and similar navigators.

This is a iNav RTH test in very windy conditions.

Excellent work by DigitalEntity.

In the latest version for Android I notice a small white circle close to the Mag in Dashboard Views.
What it that?

You can change the land speed in centimeters per second in the GPS section with the #define LAND_SPEED 100
by changing the 100 to something less which could result in a smoother landing.
My question for you now (for fly4fun, as he was wanting to know) is can you do a RTH and then flip a switch to autoland? I think he has been wanting to do that with his 328p based FC. I told him I didn't think it was possible because Land is a type of waypoint and the 328p is shy on memory for waypoint stuff. I would be happy to inform him otherwise if I'm wrong and let him in on how to do it.

Yes you can. If you use EZ-GUI select RTH as your last waypoint. To activate the land function you will need to set "1" in the "Land" option field.
This is how it's done but I haven't tried it yet.

Using a 328p with waypoints is risky. A risk I didn't want to take and thus switched to FC's with ATmega 2560 chip set.

On a different note concerning EZ-GUI: I just got myself a new smart phone. It's a Samsung S5 Neo with Andriod 5.1.1. The EZ-GUI app often crashes. Is anyone else having stability issues on Android 5.1.1?

Thanks for reply. But I think that it not necessary and confusing; to large. None of the other gauges require or have shown any type of unit indicator.
At the minimum it should be inside the gauge.

I like it the way it is. Don't change it. (It's TOO) minor a detail to get all fussy over.

Hi. This is my first post. Apologies if this has already been answered. The play store is saying the app is not compatible with my device, an Acer Iconia 8. Is there a work around to get the app loaded onto my device?

Hello everybody, I'm new here and this is my first post. I'm in University and I want my project degree be a quadcopter controlled by an Android phone. I want that my custom controller (based on Arduino ProMini and MPU 9150 ) have MW 2.4 and I want to make my own Android app to control drone (and also implement new features like Auto Land ON/OFF, depend of time that I have). Now I use EZ-Gui and it's awsome. I see that you make it open source, but version from GitHub doesn't work to control quadcopter, I think it's not fully implemented in that version. So, now I want to please you to share your code (at least that part with control). You will help me a lot if you can make this. Also, I want to contribute to your App and make new features. I'm a new Android developer, and I want to learn new things. I'm waiting for your response. Thanks a lot!

My android did a system update and now none of the maps work. The quad doesn't even show up when the GPS is working. There is no map grid lines or anything, just a blank screen where map info used to be. ???? The phone doesn't even locate to a map.???
Also, when I try to draw a mission the waypoints don't show up but they are in the waypoint list and I can clear them out and put more in. Nothing shows up on map screens. Any ideas?

Hi
Because EZ-GUI contains now paid content, it is not longer open source.
Controlling is easy enough so you will figure it out.
You have to sent MSP_SET_RAW_RC few times per second (faster is better)

public void SendRequestMSP_SET_RAW_RC(int[] channels8) {
ArrayList<Character> payload = new ArrayList<Character>();
for (int i = 0; i < 8; i++) {
payload.add((char) (channels8[i] & 0xFF));
payload.add((char) ((channels8[i] >> 8) & 0xFF));
}

sendRequestMSP(requestMSP(Constants.MSP_SET_RAW_RC, payload.toArray(new Character[payload.size()])));

}
