No, xz streaming is not supported. You can use the accounter together with accelerometer data as is.
-
That video is 2.5 years old, and as stated in the description, for an older API release. Follow the tutorials outlined on the website: http://mbientlab.com/tutorials/SDKs.html#java
-
Ok, so as mentioned in this section of the tutorial, there is a README file on the desktop (linked to the file in the MetaBase folder) that explains advanced configuration features for the MetaBase app. Did you look at that README file?
-
I recommend writing the MetaWear part of your project with the JavaScript SDK instead. The Noble ble library is way better than any of the available Python BLE libraries.
-
As I stated in my previous post: @Eric said: It's not possible with scan response. iBeacon could work but it would the API would need to support splitting the data across both major and minor values.
-
I have not been able to reproduce either issue with our Android devices. For the stack trace issue regarding the onCharacteristicRead callback function, I forced the API into throwing that exception by never reading any characteristics. connectA…

Can you also post the code for the light and accelerometer? Also, what Android devices / OS are you testing with?

Assuming you have a vibration motor attached to the board, then yes, it should be possible. Check out the tutorials we have on the website to first get an example app running. https://mbientlab.com/tutorials/SDKs.html#java

@Eric said: Are you writing your own scripts or using the MetaBase app? Please answer my previous question.
-
Refer to the code from the sample app: https://github.com/mbientlab/MetaWear-SampleApp-Android/blob/master/app/src/main/java/com/mbientlab/metawear/app/TemperatureFragment.java#L228 Documentation is back up on the site.

No, that is not what I said. What I said is that the Obj-C SDK only supports a limited set of sensors, up to what is necessary for the MetaBase app to work. Based on the code snippets you posted, you are using data filters, which is not supporte…
-
You can't directly retrieve the resistance. You can instead read the voltage at GPIO 0 and use that to calculate the thermistor's resistance: https://mbientlab.com/androiddocs/latest/gpio.html#analog-data Is there a reason why you are using you…
-
Right, so as previously stated, anonymous events are still experimental in the iOS SDK. I believe it is only supported for raw sensor data so you can't use it with data processing events or even the detection algorithms on the BMI160. Basically it…
-
And to confirm, the TimeoutException you posted above is still occurring with the API variant posted in this thread? The read characteristic error is a good starting point; I will try to reproduce it on my side. Hrm, this issue with connectAsy…
-
I've setup a test to read temp and humidity every 30 min. A few questions for you: * Can this issue be reliably reproduced? * How long were you sampling the data in your tests? * Do you have the same issues if you collect temperature data wi…

I simply pointed out the the likely root cause of this infinite wait you are seeing on the Huawei device, not that there is anything wrong with the code. Furthermore, the tutorials are to help you get started; it is up to you if you want to continu…

1) Possible but resetUid does not change unless the board reboots 2) It doesn't matter if time references change; everything is relative offsets from a fixed point in time. However, the reference points probably should not change while the boar…

I asked for the code that sets up sensor logging, not creating anonymous events.
-
What code are you running to setup the sensor logging? Anonymous events are still an experimental feature with the Objective-C SDK so it could be that you are using it in an unsupported manner.
-
Post your code and we can try it out on our end.
-
Number of log entries is not the same as number of data points. Log entry count is only relevant for having an accurate download progress.
-
Based on the above code, it seems like the reconnect attempts continuously fail, not that connectAsync never terminates. Regarding the Huawei device, try to connect to devices with another BLE app, like the nRF Connect app, and also post the erro…
-
My guess is that the label was incorrectly cut or printed given that its string is shifted byte 1 byte. You can check this by doing a BLE scan with an Android device to see which MAC address is being advertised.
-
Offhand, the IMU and fused data should be unaffected however, you will want to confirm this with with your own testing. No, 50Hz is not supported. Alternatively, you could attach a reed switch to the GPIO pins and simply detect when the digital …
-
Isn't that type of information detailed in your sensors' spec sheets (which you have yet to link to)? Furthermore, you haven't mentioned how the sensors are connected to the board so I have no idea how you are using the external sensors. Please …

Post the code you are testing with and provide instructions on how to get the API to hang on connectAsync.
