Thx Laura. Then I have another question: since there are so much data in the memory, what if I only want to download some part of it? My experience with MMR: it takes me 40 minutes to download data from 2 MMR at the same time. Since MMS memory is m…

In the email, it says "Now you can gather data for 46.5 hours non-stop when logging sensor fusion data at 100Hz (that's 67,108,864 data entries, over 67million data points!)". Consider this case: first I started logging; one hour later, I stopped i…

I got notification from mbientlab that MMS has been released. I assume all the Smartphone apps like MetaBase provided by mbientlab would work with MMS as well. I wonder if all my current code (most Python), which works with MMR, will work with MMS.

After I did data logging with 2 MMR for 2 hours with data rate at 100, 200, and 400Hz, the battery level of both MMR are still 100%. Is it strange?

The names of functions to config Acc and Gyro are a little bit confusing: for Acc, it is called libmetawear.mbl_mw_acc_set_odr; while for Gyro it is libmetawear.mbl_mw_gyro_bmi160_set_odr. For Acc ODR, the input parameter is a direct float value;…

@Laura, I read from another thread saying JavaScript is better and more reliable that Python for working with MetaWear. What is your opinion? I have just started working with MMR. Most likely I will be working in Ubuntu. I have downloaded and b…

* In the memory capacity calculator page, the sensor is able to support 800Hz data rate max. It is not true? * You said total < 100Hz; does it mean if I enable both acc and gyro, their total data rate must be < 100Hz. So 50 Hz each is the max…

Laura, I believe the original code does subscribe to both signals and turn on the BMI. acc = libmetawear.mbl_mw_acc_get_acceleration_data_signal(s.device.board) libmetawear.mbl_mw_datasignal_subscribe(acc, None, s.callback) gyro = libmetawear…

In the Python SDK, there is example code like stream_acc_gyro.py, which is supposed to stream acc and gyro data from sensors in real time. @rotemg2 In the original code, the following lines are commented out. They are there to set range and sampl…

Hi @Laura, I am OK with smartphone, however we want to combine MetaWear with other sensors in our application; so the data point synchronization is crucial. If we want to use smartphone, we have to move all my other sensors data collection to the…

I have another question: My Windows computer cannot find MMR either in Bluetooth setting when I try to add new Bluetooth device or in MetaBase when I try to add Device. I have tried Ble 4 and 5 dongles. Both not successful. What could be the proble…

Laura, thank you for the answer. Can help me confirm the following: the starting time point t of data logging is the time when the phone issues command to start a new session. Why I am asking is because we want to combine MetaWear with other senso…

Thank you Eric, This system does not email me the update, does it? Looks like I need to come back to manually check, isn't it?

where can I find that sensor fusion tutorial app?
