You need to use our Javascript or C APIs to do this. We use a custom protocol, not standard services and characteristics and we do not have documentation about this. Please use our APIs.

Can you do the hard reset while the unit is plugged in (short pins) and then use a brand new iPhone to connect to the sensor (one that has never been used before with your sensors). Do this exactly as written...don't use an android phone, don't u…

Thank you for the update!

https://mbientlab.com/community/discussion/2981/for-those-stuck-in-metaboot/p1 Also try the nordic app, see the other threads about this.

Yes, please try a different brand. https://mbientlab.com/tutorials/Linux.html?highlight=dongle#dongles

Here is the python tutorial in Windows: https://mbientlab.com/tutorials/Windows.html Here is the python tutorial in Linux: https://mbientlab.com/tutorials/Linux.html We have tons of examples, just look on our tutorials and on Github: https://mbien…

What about different dongles, have you tried that yet?
-
Is it working now that you have fixed the i2c settings?
-
It should work just fine in theory. Try it out and let us know; I haven't been able to get my hands on a pi4 to try it out yet.
-
As long as it works on a 3v power line and it's i2c compatible, I don't see why it wouldn't work in theory.

BLE data transfer is essentially a one-way communication. A Bluetooth Low Energy device broadcasts ad packets of data at regular intervals of time. These data packets are detected by smartphones/computers nearby. To save energy and provide higher…

There are plenty of free apps available: https://mbientlab.com/tutorials

Bluetooth devices send advertising packets to broadcast data, and to allow other devices (scanners) to find and connect to them. The advertising data consists up to 31 bytes of user configurable data. An additional 31 bytes can be sent as a scan res…

You need to write your own code using our developer APIs to do that: www.mbientlab.com/developers. We also have the metahub where most of the code is already written for you: www.mbientlab.com/tutorials.

The devices might have an expired battery if they worked years ago but no longer work. Did you leave them out and not charge them? When did they work previously?
-
Does it work with your smartphone and the mobile metabase app?

This looks fine, what is the issue?
-
The metal will affect the magnetometer and will slightly attenuate the bluetooth signal. Assuming the magnet is a reasonable size, no other items will be affected in any way.
-
No, the calibration available is for sensor fusion only. You can calibrate yourself in software if you want at the app level but that is your responsibility.
-
Can you do something simple and post data? Turn on the sensor fusion, rotate the device on a flat surface 360 and share the data you get. You are trying to troubleshoot your sensor doing something too complicated. Make sure it works in idle and d…

Hi Michael, You can email hello@mbientlab and we will send you the datasheet for the battery. We don't have a 3d drawing but you can recreate it from the datasheet.
-
You need to provide pictures and videos to support your claim. Have you tried charging it and leaving it plugged in? Is the battery damaged? Have you tried resetting it? Did you follow the steps at https://mbientlab.com/troubleshooting/? Have…
-
Try the higher modes (16g), as Eric mentioned, you are likely saturating the data.

Update: I think that it is not possible to stream euler and corrected acceleration from sensor module due to the fact that BLE has limit 100Hz. Can i reduce the frequency to 50Hz for both outputs? You might be able to push 120Hz (100Hz acc +…
-
Is it possible to stream Euler angles and Corrected Acceleration at the same time with MetamotionR? No but you can use the fuser and do euler + regular acc Also is there any plan to upgrade MetaMotion to Bluetooth 5? If so, will there …
