Problem while streaming data with 2 MetaMotionR devices
I own two MetaMotionR devices(Hardware 0.3, Firmware 1.4.5, Model Number 5) and i am trying to run the stream_data.py script with both devices simultaneously. I run it on ubuntu linux 16.04 lts with python 3.5. Firstly before a connection is established with each sensor, an error message is printed in the screen stating the following:" error 1570631669.229802: Error on line: 296 (src/blestatemachine.cc): Operation now in progress". The program continues its execution and the sensors begin to stream the data at 25 hz as it is configured in the stream_data.py script. After 30 seconds when the program stops, there is a large difference in the data that each sensor streamed. The first sensor that connects is always streaming at a lower frequency than the second. So the total samples for example are something like 440 samples for the first device and 754 samples for the second. When i configure the frequency to be 100hz the difference is even bigger, having a total of 400 samples for the first device and approximately 3000 samples for the second.
Please advice on how to troubleshoot this,
