Here is some information: https://www.raspberrypi.org/documentation/linux/usage/root.md

Can you run it with sudo?
-
It's either the SD card or the Pi. Is there any way for you to check if it works with a different SD card (you would have to load Raspian on it - https://thepi.io/how-to-install-raspbian-on-the-raspberry-pi/). Then see if it boots with a fresh Ra…

Do you want to share how you fixed it for others who might have the same issue?
-
Can you post your code and replicable steps?
-
Great news!

My answer is still yes. www.mbientlab.com/tutorials: You just call startAccelStream() and then startGyroStream()

@abcd, Try the hardware reset here: www.mbientlab.com/troubleshooting. Then use a brand new iPhone + MetaBase App install (NO ANDROID - SMARTPHONE ONLY) to connect and update the board.
-
The fuser isn't used to stream two signals at once, it is used to pack sensor data. So by default the APIs and MetaBase App are setup to stream up to 100Hz of sensors at the same time, it could be 25Hz Acc + 25Hz Gyro + 25Hz Mag + 25Hz light OR 5…

It's a raspberry pi so you shouldn't have any trouble booting it. Just follow the steps here: https://www.raspberrypi.org/help/quick-start-guide/2/ Please note that the SD card is already provided and comes with Raspbian + MetaWear pre-installed. Y…

good luck! keep us updated.

When did you buy this device? We are currently on firmware 1.4.4 and yours is on 0.2.2. Did you not update for years?

Bluetooth 4.2 has a max theoretical range of 100m (outdoor line of sight). In typical applications the range is about 10m indoors and 50m outdoors. What does "weak" mean? Are you sure you understand the range of BLE as per the spec? Our Senso…

No it cannot.

If you are running on a small system like a raspberryPi, can you try to increase the swap? https://wpitchoune.net/tricks/raspberry_pi3_increase_swap_size.html http://www.linuxandubuntu.com/home/how-to-create-or-increase-swap-space-in-linux Can …

The magnetometer data looks fine. It is raw so if you want a smooth curve, apply a filter.

You should first learn Python and get comfortable with it: https://www.codecademy.com/learn/learn-python Then you should go through our Python tutorials and really understand our APIs: https://mbientlab.com/tutorials/WPython.html# Finally, you sho…

I recommend getting familiar with the Python language by doing some tutorials: https://www.programiz.com/python-programming/methods/built-in/print Please note you should be a confident developers when using our APIs.
-
The unit are 'g's. The data you get is raw. When you get x=.453, it means .453 g's have been measured in the x axis at time t. A single G-force for us here on planet Earth is equivalent to 9.8 m/s^2 So if you want to go from 'g's to m/s^2 you…

The datasheet has this information: www.mbientlab.com/documentation
-
Read the source code: https://github.com/mbientlab/MetaWear-SampleApp-iOS/blob/master/Accelerometer/APLGraphView.h
-
Also try this: https://mbientlab.com/tutorials/Calibration.html
-
You are streaming gyro data which is angular velocity and not an angle in degrees. If you want vectors, use sensor fusion.
-
When you download the code from the repo, you need to make sure to also download the CPP reference: git clone --recurse-submodules https://github.com/mbientlab/MetaWear-SDK-iOS-macOS-tvOS.git Please follow the instructions in the github readme: h…

React is just Javascript so just use our Javascript SDK: www.mbientlab.com/developers. Please start a new thread and post details and screenshot if you have an iOS related error. ALWAYS follow the tutorials first: www.mbientlab.com/tutorials.
