Sensors disconnection

Good Afternoon,

I have been developing a script in python in order to acquire data from 10 MetaMotionC sensors at the same time, using accelerometer and gyroscope . I was trying to acquire and save data from them during 12 hours, but somehow the sensors start disconnecting one at the time after some hours. I am trying to solve it, but I don´t know if it is a problem of memory, a problem of having several sensors working at the same time or a problem of Bluetooth low energy connection ?

Best regards,

Luís Silva


  • Are you using multiple dongles? Most BLE dongles won't connect to more than 1-4 sensors at the same time.

  • Yes, I am using 2 dongles.

  • That might not be enough. Some dongles won't do more than 3 at a time. You need to experiment with less MMCs at the same time.
