Supervisor App Bluetooth Stops

Hello,

I have been facing this issue that whenever I am trying to send interviews through Bluetooth using Supervisor app, many times the Bluetooth on Supervisor tab turns off as soon as I press the horizontal sync button.

Then I have to unpair, repair and sometimes restart the tablet to make it work.

Can someone explain it to me why does it happen and how can I avoid it?

Thank you,

In short: because Bluetooth is unreliable.

thank you @sergiy,
So you wouldn’t recommend using “Supervisor to interviewer transfer using Bluetooth” for large surveys?
