@Akash, A few things to note in our experience with Bluetooth and multiple devices: * You will have to build in code to automatically handle reconnects and disconnects * Our boards advertise slowly but BLE on Linux is FAST, so again, don't …

@thorssonmax, Sounds like a dead battery. Is it puffy or weird looking in any way? Can you fill out an RMA?
-
@yogame, Fill it out, it is on a per case basis sometimes.

Please follow my tutorial step by step for how to install metawear properly in Linux: https://mbientlab.com/tutorials/Linux.html
-
@cpn, No we do not because you will have to do the math portion yourself. I suggest starting with our Python projects and then using good old google for some help: * http://www.chrobotics.com/library/accel-position-velocity * http://www.div…

Please follow the install steps on our tutorials: www.mbientlab.com/tutorials Seems you are missing files or something is wrong in your install.

@denisb, Great, keep us updated. It seems your metatracker is stuck in log mode but works fine if you can just update or reset it with an iPhone and a fresh MetaBase install. I had this happen to someone else and the iOS firmware update fixed ev…

@mvela1, I went ahead and was able to reproduce your error but Eric's suggested fix worked for me. Here were my steps: * I downloaded your files and put them in the right folder. First I first got this error: I fixed this by removing t…

@dammage11, Yes it looks like it's an issue with the bluetooth adapter, can you make sure it's ble4.2 or above compliant? You should follow the steps in our tutorial here: https://mbientlab.com/tutorials/Windows.html Then I suggest trying with…

Hi All, Updating this thread. I did a fresh ubuntu install and tried Python examples using Python2 and Python3 and everything worked like a charm. I updated the tutorials as such: www.mbientlab.com/tutorials. It might help a few folks here.
-
Hi all, A few updates. First I updated the tutorials to include a Ubuntu based setup, please see here: https://mbientlab.com/tutorials/Linux.html. Second, I ran a few examples and did notice that a few times you may get an error because the BL…

Pictures? More info? More details? Reproducible steps please...

@Tobias, No worries, we are happy you posted on the forum. We did update our tutorials a little while ago but maybe your stuff was cached so you didn't see the changes until now. We are going to keep updating tutorials so keep checking back. …

@GaryG, Too much coding for you?
-
@c625v12, Nice job. You can use built in functions like our timers and accumulator to down-sample any sensor reading.
-
You can try to add this to the I2C line of the metamotionR: https://www.sparkfun.com/products/13763 However, nothing will be easier than just use the metatracker instead with the built in humidity and pressure sensor.
-
Can you use Python2.7?
-
Hi Sahil, Yes the MetaMotionR has a small vibration motor attached to it, much like the ones you get in your smartphones that make the device vibrate when someone rings. Please see details here: https://mbientlab.com/store/coin-vibration-motor…

@Hiro Thank you for the information!

Bluetooth is around 100ft - 30m but it highly varies with your surroundings, smart devices, and antenna gain settings. There is a nice overview here: https://blog.nordicsemi.com/getconnected/things-you-should-know-about-bluetooth-range
-
@fbytr, You just need a 4.0 or higher dongle (supports BLE)
-
Our MetaHub or Windows based MetaBase app both graph in real time. See www.mbientlab.com/tutorials (this is a forum rule btw)

Resolved

@TheDude The # of connections depend on OS, hardware, ble libraries, which metasensor is used, and which api/sdk is used. THERE ARE MANY VARIABLES AND FACTORS! As Eric said, you need to try out what works for you. I have had the most succes…
-
Works fine with Python2.7
-
why not just use the button on the device? Then the epoch time would be tied to the metasensor already (same time reference).
-
Check out tools like btmon, learn to use it.
-
Please post screenshots and more details.
-
All you need to do is look up the datasheet for each sensor and see how much current they draw in different modes. Keep in mind the sensors are not on for much time but will probably draw around 2.5mA when active and then a couple of uA while sleep…

You need to install this: https://pypi.python.org/pypi/six to install run: >>> pip install six If you don't know what pip is, then please google for pip install
