@Srinivasa, Sorry for the late response, I don't have time to look into code right now. Have you been able to get it working?
-
@jackob96 Firmware 0.2.1? We are on 1.5.5, why is your firmware so low?
-
@TalStein, Thanks!
-
Yes, all sensors are "tared" and then after that quaternions represent their changes in rotation from that start position. Quaternions and eulers are differential computations, not absolute. This isn't a GPS signal. It's your job to either set…

@gudavalli This looks like expected sensor drift. You can only fix it with occasional tares or using the magnetometer modes.
-
It will be tough for anyone to comment since everyone has such a unique application and settings. It could be a home for the elderly, a pasture field with cows, a convention with 1K people, an airport, a home in SF with lots of crowded wifi signals.…

The CPRO latest firmware is 1.2.2. This model is no longer supported. We currently only support the MMC.

1) This is not a MetaWear questions but rather a Python question. You need to modify the Python code to do this and use our APIs accordingly. I recommend taking a quick Python class and following up with our Python API tutorial: www.mbientlab.com/tu…

Please post replicable steps. See https://mbientlab.com/community/discussion/3167/how-to-report-an-issue#latest for details.

When connecting multiple MMRs and acquiring multiple acceleration data simultaneously from the multiple MMRs, are the acquired acceleration data synchronized? No, MMRs are independent of one another. The clock is resolved when the data is do…
-
Yes you can do that, please see our tutorials. You will need to write code in the language of your choice, Python, JS, Swift, Java and so on. Then learn about how to use our APIs to setup thresholds, run the code, and done!

Seems like at some point in time the data download was not finished (interrupted by a severed bluetooth connection). The best way to retrieve it would be with our anonymous downloads Python or Javascript on Linux. If you are using the iOS App, try…

Hi, Unfortunately this is not possible because we have our own custom bootloader that has to be uploaded by our tools and now you have overwritten it.
-
Hey mgardiner, you can modify the metabase or build your own app. Whatever you prefer.
-
You have to google-fu this. It depends on the hardware, firmware, OS, and drivers installed.
-
No sure on this. Can you share steps so that we can replicate?
-
Hey @TalStein, We stopped offering support ever since the pandemic due to restricted resources. Custom firmware is a beast!
-
The sensor fusion data gives euler and quaternion vectors. It is not a global coordinate system. You can do a bit of google-fu to learn more about sensor fusion. It honestly all depends on what you are trying to do.
-
There is an example of this in our Swift example at the moment. You could look at that for reference: https://github.com/mbientlab/MetaWear-SDK-iOS-macOS-tvOS/blob/master/MetaWearApiTest/MetaWearApiTest/DeviceDetailViewController.swift -> go to @…
-
Do you have code that can automatically reconnect in case the Bluetooth drops? Bluetooth isn't guaranteed so you have to handle sudden disconnects. Also make sure that your phone doesn't turn off or send the app into the background (then you wil…
-
Unfortunately we don't support custom firmware.
-
Do you have data you can share? We will try to reproduce on our end. Can you also share the hardware and OS version of your hub? Is it one you made yourself or purchased from us?
-
Hi yves, You can't calibrate the sensors in hardware/firmware. You can do it in software though.
-
What happens when you use our example App? https://github.com/mbientlab/MetaWear-Tutorial-Android Do those work for you and whats the difference between your App and our Apps?
-
In your first movie it looks like it installed just fine. You just got a warning, no errors. Your version A is good to go. Just npm update metawear and done.
-
Also, provide pictures, snapshots, screenshots, data excerpts if you have them. Visuals go a long way! Anything you can send us to reproduce the failure is of upmost importance.

Not enough information provided. Please follow the rules at: https://mbientlab.com/community/discussion/3167/how-to-report-an-issue#latest

Unfortunately this is not possible. We are releasing the MMS later this year with additional memory.
-
Hi Yochai, You can do this but you need to code it yourself using our APIs. Our MetaBase App doesn't handle this for you.
-
* No, it is reliable, you just have to reconstruct it. * Yes but you can just fix the timestamp, they are fine. The data just comes too fast for us to post-process and fix the timestamps, you can do that yourself easily.
