but when the problem is present (and only on one device and always on the same device) it is present both with the App and with python API. It seems like if this instruction libmetawear.mbl_mw_logging_stop(d.board) was ignored
-
Once again problem has vanished. I just don't know how.

Many thanks for the solution and for the advice. I will work to improve my skill. And I hope at the same time quality of examples will be improved too. Or let me dream beeing tested before they are uploaded. Just one remark 2000.0 is not an int b…

The problem is with Android MetaBase

I run the exact copy of https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/stream_acc_gyro.py command line : python stream_acc_gyro.py 'FC:26:7F:82:0A:B3' Everything runs as expected top part of the screenshoot I uncomment l…

Hi, With MetaBase App I have a group of 2 devices. I configure logging for gyros at 100 Hz 2000 °/s Duration of logging = 17 s I obtain 2 csv files one corresponding to each device one has 2 001 lines (2000 samples) the other 90 666 lines (…

Problem is back For one device the csv file for gyro is 141 kB and for the other 6.6 MB ! So it's normal that downloading times are very different. Here is plot of the time stamp for the two files For the first device (the long time one) and f…

I don't think so or the problem is in the example I made a test with the exact copy of https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/stream_acc_gyro.py for s in states: print("Configuring device") libmetawear.…

I start measurement with libmetawear.mbl_mw_gyro_bmi160_enable_rotation_sampling(d.board) libmetawear.mbl_mw_gyro_bmi160_start(d.board) and get data If I try libmetawear.mbl_mw_gyro_bmi270_enable_rotation_sampling(d.boar…

I face a similar problem, After logging acceleration (100hz, 16g) for 10s with two devices, downloading from device 1 takes about 20s, and downloading from the device 2 about 10 mn. When downloading both devices are at same distance. This tru…

Hello, It seems I have a similar problem using python API I can configure an accellerometer following the exemple https://github.com/mbientlab/MetaWear-SDK-Python/blob/master/examples/stream_acc_gyro.py with libmetawear.mbl_mw_acc_set_odr(s.de…

No it was not 5 mn per device. I made a test with only one device active and logging. And for one of the downloading lasted about 20s and on the other one 10 mn. More surprising, problem has gone ! And now downloading (short) time is similar on bo…

I had to delete the devices also and then connected them again. It works and I can log data on both devices now. Files are created But when logging accelerations on two devices with same parameters (range frequency). Downloading take 20 s from one…

Here is what I get I can configure and obtain a log file from "E6" device when I go to "FC" device I am at the same point Notice this is specific to the app. I could configure and read data on both devices using Python API. At the end of API…
-
Yes I did delete the App prior to install new version. When I first open the App the devices are still in a group I cannot make any logging or streaming. The only proposal I have is "Dowload" and when I press on "Download"
-
No improvement. It still have the "download" tag at the bottom of the screen and when I pressed on it at the first time after upgrading , Metabase I got "no logged data" for the sensor that downloaded at first attempt with previous metabase reale…

It seems I have a similar issue I use a group of two sensors. At first attempt only one downloaded I got one green "V" and an invite to try again. At second attempt the second one downloaded. The I got a second "V" I was asked to give a name…

I understand you need the noise density for accelerometers and gyroscope If so you can find it here https://www.bosch-sensortec.com/products/motion-sensors/imus/bmi270/#technical

You are right, it was just a problem of columns position. Sorry about that

@ericf said: model metamotion R Firmware 1.5.1 Use with Android I can configure the sensors, start and end a session. But I have not data in the csv file (both streaming ad logging mode) I tried with several calibrations and w…
