Frequent lockups

[standardtoaster]

Hello!

I'm experiencing frequent lockups using everything from f692226 to present, and i'm hoping that somebody can spare a bit of time to help me troubleshoot.

What i'm seeing is that anywhere from about 1 minute to 10 minutes after the device has been plugged in, it stops sending data, and the RX light becomes solid, and the TX light goes out. During "normal" operation, the RX light blinks about once per second, and the TX light goes solid. "normal" operation is defined as the device being connected and UI app (EDTrackerUI302) or open track being able to receive valid positional data from the device.

I've tried this on my PC and my mac, and see the same behavior, so i'm pretty sure it's something with my hardware, wiring or the sketch. There does appear to be a difference with my hardware where the data sheet of my MPU indicated that VIO should be kept high for the chip to send motion data.

I'm using the Sparkfun Pro Micro 3.3v with the Triple Axis Accelerometer and Gyro Breakout - MPU-6050 and it looks like this:

For clarity, i've got it wired as:

Pro Micro	6050	Button
2 (SDA)	SDA
3 (SCL)	SCL
7	INT
10		button
VCC	VDD
VCC	VIO
GND	GND
GND		button
