1.There is a limited number of loggers that can be initiated by mbl_mw_datasignal_log() True 2. Many raw sensors outputs can be logged at once by mbl_mw_datasignal_log() due to each having a small size (ex,raw Acc & raw Gyro & raw Mag &am…

Ok, your setup looks good. I don't see anything wrong with it.
-
Make sure this is. actually working: libmetawear.mbl_mw_acc_set_odr(self.device.board, 50.0) libmetawear.mbl_mw_acc_set_range(self.device.board, 16.0)

@Eric said: Metabase doesn't filter the sensor data. We checked the code for WIndows and Android and there are no filters. The data you get is the raw data straight from the sensors.
-
Are you using the Windows, iOS or Android version? I checked the code in iOS and the data is coming in raw, it is NOT filtered at all.
-
Yes. Again, you need to go through our tutorials: www.mbientlab.com/tutorials and our example code: https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/stream_acc_gyro.py
-
Yes, you would use the timestamps for that. EDIT Here is some of my gyroscope data: You can see I used the elapsed time to reverse the frequency (I computed the Hz column, everything else is data in the CSV file as it comes in from the sens…

Please see the datasheet: www.mbientlab.com/documentation.

Read our tutorials please.

Nice.

Please see our tutorials for this information.

Hey @yulum I recommend using the 'any motion' function of the MMR so you record motion only when motion occurs. Then using a smartphone or hub to do midnight downloads so that you don't lose the data or fill up the memory. The Metahub can help b…

Output of the BOSCH Sensor fusion: * Absolute Orientation (Euler Vector, 100Hz) * Three axis orientation data based on a 360° sphere * Absolute Orientation (Quaterion, 100Hz) * Four point quaternion output for more accurate data m…

On our side we've used a bit of the internal python tools but we don't have any sample code or tips: https://github.com/aws/aws-iot-device-sdk-python
-
You need to use the macro system.
-
@monitoriota, You are welcome to bother us but you need to make sure you post appropriate question with code or other supportive material.
-
Make sure to use the correct disconnect calls when using our APIs. It is likely that you are not using the right calls and disconnecting properly so you have to force a disconnect at the hardware level. To ensure a disconnect at the software leve…

You will need to do a deep down dive of the bluetooth level communications to see what the delay is. It could just be that your antenna is being used for other things (remember your ble antenna is shared with all your wifi and other ble communica…

I don't have this problem when I run it. Try to clear your sensor memory (use full_reset) and provide more information if you expect any support. My guess is you are running back to back examples of logging sensor data without clearing and/or …
-
Yes but you will need to use our APIs to downsample. For example, you can use the accumulator/averager processor to add 10 sensor fusion data points together effectively reducing the sample rate to 10Hz. Please see our tutorials and API doc for m…

I have provided example in swift, python and java for now. C# and Java will come next month. Please check our github for this example code.
-
Great. Just in case, here is in example in Python of getting components of a signal: https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/stream_acc_x.py

If you bought this dongle from us, let me know and I can send you a new one (just email or file a ticket). I am glad everything is working. Thanks for the update.
-
This is odd. It seems everything is working just fine independently. Can you do one more thing for me: 1. Plug in the Dongle 2. Run these commands >>> sudo apt-get update >>> sudo apt install bluetooth pi-bluetooth …
-
Can you remove the dongle from your system and run two two commands again, lsusb and hcitool dev (again no dongle). I think I know the problem but this will confirm my theory.
-
Are you sure the device is advertising and not connected? Can you verify this with a phone? Can you take a screenshot and prove to me the MetaSensor is advertising and NOT connected to anything? What does >>> lsusb AND >>> hcito…
-
Both devices we purchased can connect to my Android phone via Bluetooth, allowing me to collect a stream of quaternion data on my phone using the MetaBase app. This doesn't look like a metawear issue at all. It looks to me like an issue with…

Hey @mgeorgi, I'll upload it here for now. I don't believe the pins changed.

Did you run it with sudo?

1) How long the battery is going to last when used at sample rate = 100 Hz, with both accelerometer and gyroscope recording? Probably 4 to 8 hours. 2) Can I use the device "offline", and retrieve data later? Yes
