Questions about setup and how to proceed

What I currently have is this - A nanowii flight control board connected to a quadcopter in QuadX form. The motors are simple DC motors so they have been connected with using transistors. The motors will be controlled by PWM.

I have been able to successfully compile the multiwii 2.3 code and upload it on to the Nanowii board. I have connected the Multiwii GUI and have been able to get readings. When I would physically move the quadcopter I would see the accelerometor and gyroscope reading changing as desired. I pressed on Calib_acc while quadcopter was placed on a flat surface.

Now I have the following queries (bear with me as there are too many - its my first time

)

1. When I connect the battery supply one of the motor starts to run on its own - is this normal ?

2. When I have the battery supply connected and I connect the quadcopter to the computer using a usb cable the other motors start to run immediately - is this normal ?

3. When I start of the GUI the values of the different channels (THROT, ROLL, PITCH.... ) remain at 1500 even when I try to change them - is this normal ?

4. I am unable to change the speed of the motors using the GUI - is this the way it is meant to be ?

5. Is the calibration of the accelerometer the only purpose of the GUI ? If not then what else am I expected to do ?

6. I have not connected any channels on the nanowii board - the THROT, ROLL, PITCH etcetra as I would like to control them serially using a bluetooth module controlled from either keyboard or an android app

a) Is the method mentioned above possible ? If not why not ?

b) Do I need to make any changes to the code (I am using the 2.3 multiwii code) ? If yes then what all changes, please help me out as I am very new to this.

c) Does the bluetooth only need to be connected to the RX/TX pin of the board rather than all the different channels on the board ?

d) Could you please suggest suitable android apps ( like this, if not this one http://www.youtube.com/watch?v=wn9FYavojgw ) that allow such control of a quadcopter? If yes please do mention all possible ones.?

Also please let me know if any changes have to be made to the code, if yes, then what changes?

e) How can I do the control from the arduino serial port using bluetooth from the computer ? Do i need to make any changes to the code, if yes then what changes ?

I have read through this http://www.multiwii.com/wiki/index.php? ... l_Protocol and not understood anything

What commands will i need to send in to control the quadcopter - please give examples for all of these functions

Starting,
Moving up,
Moving right, left, down
Staying in the air at the same position
Stopping


7. Am I missing out on something or do I need to change something ? If you would like to recommend any resources please feel free to do so.

I would like to thank in advance anyone who takes the pain of helping me out.

I would love to help you on this, though I am just starting out myself. This sounds like an incredibly complicated set up for a first shot. Have you considered a KK2 or Naza set up?

I hope you find your answers

Thanks !

Well I am not familar with the setups that you mention but I actually have to mange with the electronics already available for me - which was the nanowii in my case :)

Mr take no prisoners!
In that case I highly recommend finding a multiwii specific forum, there is probably good help at rcgroups.

I have actually tried at other forums but so far I had no success. Please if anyone can help me I would really appreciate it :)
