Problem description

When I'm trying to sending multiple form instances, I have an issue java.io.IOException: socket closed, I guess that when I finished the first form transmission, the UploadJob.java will close the bluetooth socket so the next form transfer task will have the socket closed issue. I don't know whether this issue are the same using WiFi hotspot, the hotspot method didn't work in my device so it's hard for me to test.

Steps to reproduce the problem

Send multiple form instances and see the log from the sender device.
