@Force, It is not possible to lower the ODR of the mag in sensor fusion as it is automatically set by the Bosch library.

We had another user say it worked on RaspberryPi4 but as I have not been able to acquire a PI4 for myself yet, I have not been able to test it. Our image just might not work on the Pi4. We will have a new image coming out at the end of the year a…

Do you have any issues with other Android devices?

I mean conn parameters on the metawear side: libmetawear.mbl_mw_settings_set_connection_parameters(self.device.board, 7.5, 7.5, 0, 6000)

You may want to try to play with the Bluetooth connection settings.

Find a library that does the conversion for you.

Quaternions are used to combat gimbal lock.

Hey brutalitops, Currently we don't display the name in the cloud dashboard. I will happily send this feature request to our engineers when we update the dashboard.

You need to log using the timer module: https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/log_temp.py This is a dev board, please try to debug and develop: https://github.com/mbientlab/MetaWear-SDK-Cpp/blob/master/test/test_lo…
-
Yes, you can log gpio data. See our logging tutorials.
-
First start here: https://mbientlab.com/tutorials/Apple.html Since swift relies on the cpp, just use the python gpio example and translate it to swift. https://github.com/mbientlab/MetaWear-SDK-Cpp/blob/master/test/test_gpio.py Add this bit t…

I am afraid you might need to look into this. Some OSs and phones require pairing...it's obnoxious....see if you can find this info on the Pixel docs.
-
Can you try the same code on another Android device, maybe a year or two old (older hardware and OS)?
-
Again the timestamp is created by the device used to download the data, for example, if you use an iPhone and our MetaBase App, the timestamp is created by the iPhone clock. Please think about that when you are working on your App; the sensor has no…

Don't bond, don't pair. Only connect. We don't support bonding or pairing.

@rabee05, follow @nakos suggestion and also you can use our battery reading API to do a bit of research on how fast the battery is spent during your sessions. You will need to experiment here.
-
Timestamped are synched to the bluetooth device used to download the data from the sensor. If you use two different devices and they have different clocks, you could see disparities between final timestamps. Also, try to get more data samples and…

You should follow the steps at www.mbientlab.com/troubleshooting to figure out what the issue actually is. If you think it's a defect and your item is under warranty, you can file a claim here: https://mbientlab.com/support -> file a ticket Yo…

@jhans, follow @nekos's suggestion.

You are streaming too fast and beyond the capabilities of Bluetooth Low Energy. BLE is 100Hz TOTAL. 100Hz device to device. 100Hz per antenna, per dongle, per bluetooth smart device, per ipod, per iphone... BLE = 100Hz, that's the max speed of t…
-
Does it have to be paired? MetaWear sensors do not require to be paired and Apps should be able to reconnect in the background. What you are describing seems to be the way Bluetooth behaved years ago, are you using an old OS or system?
-
@wang111, thanks. Since Matlab doesn't support BluetoothLowEnergy entirely yet, it has been too much of an unreliable hack to get streaming to work and we don't want to give our users a "hack". Once Matlab fully supports BLE, it will make a lot of …
-
Great news @JMoody. Perhaps the sensor was doing other things internally that were eating up bandwidth? Glad it worked out
-
Not sure this falls within metawear territory. Might have to refer to stackoverflow for this one.
-
Yes it can be done on the board. You could use an averager to downsample for example: https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/acc_threshold_detector.py Another great example of this is how we use the timer module bu…
-
It is 100Hz if you have nothing else streaming at the same time. Can you confirm this? Also the default = 100Hz for Sensor fusion, so you should be naturally getting this. Can you check your BLE? Are you using a dongle? Can you please run o…
-
Hey wang111, we only support importing data as a CSV format into Matlab. We no longer support streaming into Matlab.

You didn't follow the tutorial or warble would be installed. Try again from the beginning. FOLLOW THE STEPS EXACTLY AND DO NOT SKIP A SINGLE ITEM (Go through the Python 2 installation before Python 3): https://mbientlab.com/tutorials/Windows.html

As per my last message. Use iOS.
