Hi.
I know how to change the baud rate in arduino code. I will wait if you add the selection of baudrate in the GUI, it would be a good feature.
I have noticed one small maybe a bug. As i am using only the sensors from multiwii i disabled the hardware ADC. I enabled the RSSI, Main voltage and Current read from multiwii. On the OSD the current was shown 0.0A but the consumption of mAh was shown properly. As i turn the ADC again on the current readout started to work. Maybe it is a small bug.
