Does it work on an iPhone and Android device?
Can you send information about your Windows machine?
Your link doesn't work. Post on Youtube.

• Does it crash if you stream other data?
• Does it crash if you log the data instead?
• Has the app worked before?

I tried Android. I managed to start accelerometer, but not Quaternion. However, In my windows - i cannot start the accelerometer

Can you send information about your Windows machine?

- dell Latitude E5540
-Inter Cor i7
-8G ram

->An update - now i recognize that all 1.4.4 sensors having this problem. the only on 1.4.2 can connect and start quaternion

yes also if i start accelerometer from MetaBase

• Does it crash if you log the data instead?

i get these values when i start quaternion in code:

Quaternion = {W: 0.000000, X: 0.000000, Y: 0.000000, Z: 0.000000}

when i try to get the calibrated status i get this message :
"Did not received calibration state within 250ms"

• Has the app worked before?

Yes. I can strat quaternion for other sensors

->An update - now i recognize that all 1.4.4 sensors having this problem. the only on 1.4.2 can connect and start quaternion

@abcd,

I ran on my Windows10 machine with a MMC at 1.4.4 and it works fine. I tried both logging and streaming quaternions and the data was perfect:

Can you please:

• Update your Bluetooth drivers: https://support.microsoft.com/en-us/help/4028443/windows-10-update-drivers
• Delete then Reinstall the MetaBase App: https://www.microsoft.com/en-us/p/metabase/9nblggh4txj3
• Reset and/or update the board firmware to 1.4.4 using the MetaBase App on a Android or iOS phone (NOT ON THE WINDOWS MACHINE). Basically follow ALL the steps here: https://mbientlab.com/troubleshooting
• Once this is done, try to use the MetaBase Windows App, connect to your 1.4.4 sensor and try logging quaternions in streaming mode only (nothing else).

Get back to me on this.

I am talking about logging data with MetaBase.

Try doing a full reset through the device information screen.
