MultiWii

hello,

I want to make my own copter, but i encounter many problem.After several months,i still not made it.so i need some help,maybe some genius here can help me ...

I want to build a hexacopter by arduino Mega(not a off-the-shelf board),and i want to controll it via bluetooth(in fact,the EZ GUI ground station).

in first step i just want to let the mpu6050's data transmitted to my android phone.then,use EZ GUI to send data to Mega board.

here is my connection

HC05-----mega
Tx----------RX1
RX----------TX1.......here i found some reference says that HC05 need to connect to TX1,RX1,but i forgot the webs
Vcc---------Vcc
GND--------GND

MPU6050----mega
SDA----------SDA
SCL----------SCL
Vcc---------Vcc
GND--------GND

pin3~8-----led
(here i use LED to simulate motor ,i wonder if this is the problem because i don't actually use ESC)

my multiwii version is 2.4
(i dont know what's the difference, so i use the latest)

in multiwii 's config , i don't choose IMU board. I just choose the independent sensors which is MPU6050 only.
others config remain the same.
---------------------------------------------------------------------------------------------------------------------------------------------------
now the problem is:
1)i use EZ GUI and connect the bluetooth. then i can read the data from mpu6050 ,also in multiwiiconf.
But in dashboard 1 in EZ GUI there are 3 components which is ARM , angle , horizon ,is red. (but the right side board change as mpu6050 changes)
2) When using radio to send some command is invalid ,also in multiwiiconf.and when i lean mpu6050 , the output dont change (to balance my copter)
3)when connecting HC05,the led on it blink slowly,in fact is blink twice and dark for about 1 sec.But i see other vedio,it light constantly when connecting successfully.

----------------------------------------------------------------------------------------------------------------------------------------------------
This bother me so such,i really want to DIY this.
i think there must some genius do this project before.
if there is any info,I appreciate very much if let me know(any kind of info)

Pleazzzzzzzzzzzzzzzzz help me.
Thanks in advance!

.

thanks for ur reply!
but i think i dont understand totally what you mean.

and,yes,the radio is the function in EZ GUI(not a real RC remote controller).
I think this is used to simulate the real controller.Is this my misunderstanding?

btw my arduino board is arduino Mega,which is official board.
it is even not used to flight controll.
i think this is the key problem.

you say,
"You need some way to switch the AUX functions and you don't have one.
Bluetooth and EZ GUI does not have all of the functions you will need to fly."

well,i actually dont need so many function.
i just want it to "fly" (balance and can control by bluetooth)
(no GPS or other fancy function)
i remember i saw some video (youtube) can do this(?)

and i sae there is AUX in EZ GUI,is that what you talking about?
---------------------------------------------------------------------------------------
Not related to above, i think i may make my motor(LED) work by multiwiiconf first.
the function of multiwiiconf and EZ GUI are almost the same.
now the problem is no one(multiwiiconf or EZ GUI) can change the output voltage of motor(LED)

.

thanks again
be honest,im new to multicopter
could you please tell me how to set up step by step?
i think i may give up my project,like previous, and rebuild one
i still cant figure out whats wrong with my connection or code.
could you help me?

hi,

Did you tryed to change the baud of your HC-05? because the baud by default is to 9600 i think and multiwii is using 115200. If you didn't change it there is this nice instruclable to do it
