Mikrokopter Mikrokopter Flight-Ctrl v2.1 problem

[zub92]

When I replaced one bl-ctrl motor was spinning in wrong direction so I replaced wires and from that point I can't do nothing more - It always shows solid red led light on the FC(LED2 is only working).


All the others ESC works normaly and fine so I don't know where is the problem. When I power it beeps like every time - nothing is weird or wrong about it. I also tried uploading new firmware(s) but with no success...

zub, when you go to MKtool, hold the control key and hit the Settings button, it will take you to the BL settings pages where you can select individual BL's and see/change settings. I forget which firmware version it was but at one point they made it so you can change the direction of the motor in the BL without having to swap out the wires.

I would try removing the wires for that one BL again and seeing if the problem clears. or use a magnifying glass to see if there are any strands of wire shorting across the motor attach pads.

those BL's and the PDB are a huge pain in the arse but once they're set up correctly they work great!

Problem is that in this moment I can't even connect it on my PC so I'm not able to do a swap that you just mentioned :/

Also I tried to remove 1 by 1 BL and there is still same thing.

start with the simple stuff.....disconnect the PDB from the FC and see if the FC will connect to the computer with MKtool....you'll need the jumper on the MKusb since you won't have power from the PDB.

Can you connect to the computer with just the FC?

 

[zub92]

Yes I also did that - remains the same: I can't connect.

if that's the case then i wouldn't spend any more time on the BL's until you can get the FC functioning again. what happens when you plug the FC into MKtool? It just says No Data?

do you know how to update the FC firmware? if you're sure everything is hooked up correctly and that your MKusb is working correctly then the next step might be to reflash the latest firmware onto the FC.

When I connect FC it says no connection. I know and tried with several different other firmwares and kopter tools...do you think that bootloader is the problem maybe?
