This App is used in conjunction with an XOnano bluetooth product. When a compatible XOnano bluetooth device* is within range it will show up in the "Choose Device" menu. If desired you can set a nickname for the device. When paired with a XOnano product it will allow you to see and record the voltage data that is produced. This app will allow one to record 1 to 8 channels of data simultaneously. To record simply press the record button at the bottom of the screen.
Through the "Calibrate" menu one can change the DC voltage offset as well as the visual voltage multiplier. These adjustments do not reflect in the recorded data and are only for visualization. After you have finished recording you can click on the "Saved Recordings" and select the recordings you would like to share. The same data captured at a faster sample rate are also found on the SD card on the PCB.
*This board still is in early development and so we dont have the boards readily available so we would ask that Apple accept a recorded demonstration of the hardware.
