Multiwii Pro Blue Flashing LED

[freakybwoy]

Hi guys,

What a great forum!

I';ve just got into Quadcopters (been flying planes for many years), and decided to buy a 450 frame and a MultiWii Pro FC from HK.

I have it installed and loaded 2.2 FW onto it. The thing flies, although it needs setting up.

The problem I have is that I can';t seem to find anywhere on the web which explains what all the LED lights mean.

At the moment, I have a BLUE flashing LED and I have no idea why it';s flashing. I have done the ACC calibration and the MAG calibration but still it flashes. It';s a steady on / off kinda flash.

Any ideas?

Many thanks,

Matt

You should notice that one of the LEDs blinks when the quadcopter is tipped away from level. It';s an indicator that shows the gyro is responding properly.

This may help as well;

LED status signification

At initialization:

    a short blink means there is no ACC connected (Nunchuk or other)
    a long blink means there is an ACC connected (Nunchuk well recognized or other)

During field setup via LCD:

    there is a fast blink at the beginning of the setup mode, and at the end
    there is a fast blink when a parameter is increased/decreased, and when the parameter is changed

After the initialization:

    LED is ON when the motors are armed
    LED is OFF when the motors are not armed

General issues:

    The blinks at the initialization is very long (more than 5s): it is sometimes the case with a WMP+NK configuration. A way to correct this is to increase the INTERLEAVING DELAY in the sketch. (from 3000 to 3500 or 4000)
    The LED is permanently blinking: it indicates a wrong connection between I2C devices and the Arduino (maybe a switch between SCA and SCL lines)
    After trying to arm, the LED stays off: check your RX connection and set correctly the radio end point to match the range 1000-2000 in the GUI

I can';t remember exactly, but this from one of my bookmarked threads may help

If you flashed new firmware to FC , blue LED blinks because you have to do acc and mag calibration. Then it stops blinking. At least on my board i have that blink always after clearing eeprom then flashing fresh MW 2.2.

So if you haven';t used the MultiWiiGui app to do this then that may be the answer to your flashing blue LED.  As I recall with my MultiWii Pro 2 (also from HK) the blue LED flashed during initialisation and then went solid.  So try the calibration from the GUI and see how you get on.
