There is an example of how to hook it up to a 5V arduino here, just make sure your voltage divider is for a 3V power (and not 5V like this example): https://learn.sparkfun.com/tutorials/flex-sensor-hookup-guide/all

IP40 = water resistant. You should google this, there are many charts available on the internet. IP Ratings First Digit (intrusion protection): 1. No special protection 2. Protection from a large part of the body such as a hand (but no protect…

You really should be looking at our tutorials which is the #1 rule for the community as this information is already provided: https://mbientlab.com/tutorials/WPython.html#macros Also here are the links to the examples: https://github.com/mbientla…

This is in our matlab tutorial but it is in python (this examples stream quaternion data into matlab): https://github.com/mbientlab/MetaWear-Tutorial-Matlab/blob/master/echo_quat_server.py

The pdf files are datasheets...there is literally a datasheet column...http://mbientlab.com/documentation/

Simply reset the sensor or firmware update. Your Sensor is currently connected to another App or cached by another phone or the same phone (maybe you have two Apps opened...). Either way, just reset it.

Always keep your projects simple. The more modes you support the more bugs your product will have, the harder and thus more costly it will be to develop and so on. As they say: Keep it simple!

@sadul, You are describing a GPS sensor, not a 9-axis sensor which provides orientation as 3d vectors. You can learn more about this here: Manon Kok, Jeroen D. Hol and Thomas B. Sch¨on (2017), ”Using Inertial Sensors for Position and Orien…

This is not strange behavior at all. This is exactly what Eric described and as intended by Apple and our MetaBase App. An Apple App doesn't know the BLE ID until after the first time it connects to the sensor (Bluetooth peripheral/slave). Her…

@mpollind, Cool. Keep us updated. Please note our APIs are open-source so you can dig into the source code as much as your please.

Hi Greg, We only support Peripheral and Broadcaster modes because of the firmware we use in the nrf52. That being said, Nordic does support other roles and also supports multiple roles at once but you would have to do that firmware development…

Follow the tutorials from the start, your installation is not complete: https://mbientlab.com/tutorials/Linux.html

This looks like normal behavior. There is an option for calibration: https://mbientlab.com/tutorials/Calibration.html It could help.
-
This is already available using our APIs: www.mbientlab.com/developers (and also note they are open source so you can change whatever the code is, in the manner you please)

@ptsg said: A few Questions: 1. Is there a way to tell how much power usage will be (on paper?) 2. Can i log for an entire day and read it once (a day)? 3. is there a way to log battery? Thank you for your time! 1. No,…

FIRST RULE OF THIS COMMUNITY IS TO READ THE TUTORIAL. YOUR FUTURE POSTS WILL BE REMOVED IF NOT APPLICABLE TO THE FORUM. 1 . Is there any indicators for streaming or logging on the MEATBASE app ? I mean how I know if sensors data are still stream…

@thorssonmax, Please provide actual data, photos, and reproducible steps to the issue.
-
Delete/Clean everything and follow the python tutorials EXACTLY. It has worked for myself and everyone else so far. There is something corrupted in your environment.
-
@metamotion_user, Actually I used a virtual machine for the tutorial I wrote, please follow it: https://mbientlab.com/tutorials <- go to Ubuntu Linux section We aren't responsible for VMWARE related issues on this forum so please send futur…

@arifreza007, The link Eric sent you already has this item answered and links to firmware and related items. Future duplicate threads will be deleted.

You will need to do a few things to save battery life: * turn off all unused sensors * use logging over streaming * reduce the amount of bluetooth connections * reduce sampling frequency After that, if you have a MMR, you can use a batte…

Thanks for the update. You should be up and running quickly with Python. Worst case, you can just google "how to upload a csv file into blender" and there may be other folks who have already solved the problem for you. It would be nice and easy …
-
@snovotill, The MetaBase App behaves this way on purpose (as intended and coded, the internal memory of the sensor is cleared once a download finishes). What you need in terms of functionality is available in our example Apps and APIs. I recommend…
-
Taking bad snapshots of code will do you no good here. Do you have debug logs? btmon logs? Failures from the IDE/compiler/debugger? Sending us snapshots of random code is about as useful as sending my grandma to help you... If you do not provid…

Bad news, Windows only support/allows 1 dongle. You are welcome to complain to Microsoft about this.
-
@Safaa, It clears itself automatically when you download the data into the phone. You do not have to worry about data/memory management at the sensor level at all.
-
Is there any reason you didn't post that part of your stream (this info is missing from your Feb 25th post)? Can you send us the script to replicate this?
-
Did you follow the tutorial? What fails? Can you post screenshots? It's difficult to help without ANY INFORMATION AT ALL TO GO ON here.

I am not sure I understand the issue here, you can just attempt to reconnectvafter: disconnect error: "The connection has timed out unexpectedly." In fact, your app should automatically re-try / re-connect if there is a conn failure.
