Hi,

I uploaded the 2.1 software today. When connecting the configuration application i now get no readings from any sensors.

Hit submit too soon:
- my copter operated well on 1.9, after upgrading to 2.1 i experienced this problem

I resolved this by going back and comparing my previous working config.h file (v 1.9) with my new non-working config.h file (v2.1) the difference was that:
- #define INTERNAL_I2C_PULLUPS was commented out in the 2.1 version.
- #define INTERNAL_I2C_PULLUPS was uncommented out in the working 1.9 version.

uncommenting it out resolved the issue and I am now getting great readings

hope this documentation helps out any future users that experience this.

Hi,

I have the same problem with no readings from sensors...
I have uncommented the #define INTERNAL_I2C_PULLUPS but still no readings...

Is there anything else i should look for?

Thanks
Rodrigo

Tried this, but did not work for me. Would anyone be able to upload a working sketch for the v2.1?

I have just tried the above with the online configurator and had no success, again the little picture of the quad no longer spins around and the rool / pitch don't move............... any ideas anyone?, plus a diag of the connections?

Also my gps although enabled in the config as per the correct one (I'm Sure) doesn't light up in the multiwii config programe

Well what an amazing board................. all it has managed to do now is blow up rx and two esc!, fantastic!, in only I had followed my instincts and gone for the kk 2 board

aboard from the tons of waffle on this board i.e loads of chatter and nothing definitive i.e a working config.h there is no real great resources on it, im totally disillusioned now
