i'm using sodaq explorer and having the same issue.
Using serialUSB for debbuging, and after disconect and reconect, the cable, i close and re-open the serial port in the device administrator in windows, but data exchanges stop working between sodaq and terminal application on windows.
Can someone help me with this issue.
There are some work around to correct the issue? May be some software trick?
Only powering off and on the board again, the connection is restored.
Thanks in advance.
