512 is not enough to cause an overflow in the angle calculation. The attitude singularity of axis near 90deg is normal, and is only a transition state. It can't cause by itself a sudden flip starting from a level state. Ok, then i have recreate the problem and investigate further on what happened. ...

Hi toshirotamigi, The 1g value for BMA180 should be +512 normal and -512 inverted. if you rotate the quad for more than 90° on one side it seems that some attitude calculation overflow (the image of the quad is oriented wrongly on the configurator) Could you describe this little bit more, or attach...

I think that there are problems with the augmented resolution for BMA180. After a bad crash i had today after activating Stable Mode (the quad instantaneously gone on one side and crashed to the ground before i even realized what was happening). After some checks on the gui i seen that now the 1G va...

Hello,
I'm interested too.
In the meantime i found this:
http://code.google.com/p/btstack/
that is a bluetooth stack that should support SPP on iphone.
I have to investigate further but it seems to be what we need to use iphone with bluetooth module.

@ Alex: It's possible make what Thoshiro says?? Thank you. Yes, it can be done and it is not that much complex. Obviously at the beginning I would enable such a tool only with motor disarmed(it involves only fairly simple processing but I think is better to be absolutely sure it does not interfere ...

as promised: this is the modification in firmware (just add the "serialize8(vbat);" where shown in the following code: serialize8(activateCamStab8);serialize8(activateCamTrig8);//82 serialize8(vbat); // <-- AM: added to send vbat serialize8('A'); Add the following pieces in the configurati...

Yesterday I was thinking about this. I think that's a better idea (at least in the first stage) to add in the firmware some very basic console command to be used using a simple serial terminal. In this way you can use one of the various Bluetooth terminal program to adjust the various parameters wit...

I've done a very simple addition to the GUI/firmware: Battery voltage value is displayed in the GUI. This can be of some interests for simple telemetry when using some sort of wireless connection. tested in short range using bluetooth. I'll post after some other tests later this evening, as soon as ...
