I am tracking the XYZ rotation using the IMU that comes with the Core2. Reading as fast as FlowUI will loop.
These are sequential readings over less than one second :
{"deviceName":"M5-Integer-Device","readings":[{"value":{"x":"-71.267","y":"0.26","z":"-14.198"}}]} {"deviceName":"M5-Integer-Device","readings":[{"value":{"x":"-174.336","y":"2.061","z":"-12.275"}}]} {"deviceName":"M5-Integer-Device","readings":[{"value":{"x":"-9.313","y":"16.855","z":"-42.947"}}]}

These readings would indicate the unit is tracking a knuckleball, but it is stationary.

What is going on?

How do I calibrate or reset it?

If I don't catch the startup menu in the first second it loads the Wifi connection and lands at the screen with the API KEY displayed with instructions to load the online IDE for UI Flow. Can this screen be cleared to get the menu back or do I have to reset the unit and try again?

Thanks in advance : )

This has not happened since I posted this question so I am going to mark it solved. I also got an answer to question 2 and am off and running with the device despite not getting any answers here.

Background: received today -
followed start guide for UIFlow_Core2,
USB to Windows 10 machine
burned and started OK. Configurated OK.
I had not run any programs and there is no sdcard.
verified correct USB driver via code on unit.

Issue: At some point the screen turned white and then faded quickly to black, and continued doing this black-white-black. I reset and restarted and it resumed after boot - no start menu, no beep.

The only fix so far is to re-burn

To repro issue, I found that when I opened the configurator after re-burning, the same blinking commenced after reading settings. Not sure if it was truly a repro or coincidence.

Question 1: what is going on here? Is this known?

Question 2:
I would like to verify that the device is on my Wifi: I entered the settings from my PC to connect while burning, but I do not see the device on my router. What am I missing?

Thanks from a newbie!
