Made my first boo boo

[philtrum]

Just been checking out all my new shiny stuff from RCtimer for my quad, and thought id connect my flight controller up at work today and get the bluetooth working ....
but, i did not realise the multiwii se v2 does not come with a usb port, and you need to buy an adapter, what a muppet

should have gone for the cirrus aiop board, with all the extras you have to add to this board, it ends up nearly the same price !! grrr

can you do it all by the android bluetooth ?

its got v2.1 firmware on there atm

Hi Phil,

Unfortunately, you cannot use the BT to upload the MW firmware. I have tried this a few times and in theory you would expect it to work as it';s just another connection to the board and I don';t think the MW firmware has any provision for bluetooth which means it';s all part and parcel of the hardware. So, from my experience, you have to use the FTDI adaptor for this.

Once you';ve uploaded the MW firmware, you can then use the BT to view your settings using WinGUI and also change them on the fly if needed.

Hi Stef
thanks for the quick reply, looks like another order to rctimer grrrr

I assume I can use the v2.1 multiwii to get me started and then flash it at a later date.

Thanks again
Phil

Hi Phil,

Yes, you can upload new firmware at any time. If you plan on using the Bluetooth Android App then it only supports MW 2.1 at the moment anyway.

Phil - if you are in a hurry you can buy FTDI devices locally. You';ll just end up paying a bit more to get it quicker;

I have one of those - works fine.

[philtrum]

Thanks, ill prob end up ordering one, I assume that I can edit all the pi';s and configuration from android without ever needing to plug it up.to.the pc ?

update :
just been through the multiwii android app, there does not seem to be anything to change the multi type from quad to tri for example, so fingers crossed its set on quad

Thanks Fruitsalad

wish i had seen your post before I placed the order with rctimer as its a similar price .... oh well, another lesson learned

just ordered

so at the same time, i threw caution to the wind and ordered the gps and additional board, in hindsight would have been better to order the aiop and sell this one on ebay lol

and

whilst i now know the barometer on the board i have is not the best, at least this will give me something else to play with and get the feel for gps

[philtrum]

just done a comparison for anyone else looking at this board ...

Multiwii board
http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=761&productname=

usb connector
http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=684&productname=

module to allow you to connect a gps board
http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=762&productname=

totals $40

the AIOP board has better barometer and built in usb / gps interface (still requires the gps itself)
http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=765&productname=
$57

so for 17 dollars (£11.26 approx), you get a much better board .... lesson learnt, sometimes cheap is not cheap

Hi Phil,

Great post. Yes, as you have the bluetooth, you can change the PID and all other settings through the WinGUI on your bluetooth laptop or using the Anderoid WinGUI on your phone. I personally use my phone as the interface is nice and I can carry it in my pocket and it';s easy to try new settings quickly.

Here is a link to the Anderoid Apps...

Be warned - none of these currently support MW2.2. So, you have to use MW2.1.

Stef - i';m using the second one of those two with multiwii 2.2 without any problems.

The ez app doesnt work for me either with mw2.2  not really had the time to mess with it to much though maybe its something Im doing wrong

[nosmo]

Both of those apps ';appear'; to work for me - ie they give readings and live data feedback

I havent tried changing any settings yet though

You have to be careful as they appear to work, but writing to the incorrect registers. The second one that Chris is using is now MW2.2 compliant, so make sure you are running the 2.2 version. The first app will work and will read the register values from your quadcopter, but if you write the values back, they will go into the wrong areas and can really mess up your quad. Luckily I saved my setup before leaving the house, so it was a simple return trip home to reload the original before i could fly again.
