I run “awconsole.exe -c 172.31.0.224” , this command can add the device in the connection list, but can’t connect to the device.

How can I connect to the device via awconsole.exe ?

A. Run "AwConsole.exe –s” to discover AnywhereUSBs.
B. Make note of the IP addresses of the discovered AnywhereUSB(s).
C. Run “AwConsole.exe –c x.x.x.x” where x.x.x.x is the IP adddress of the AnywhereUSB you wish to connect to.
D. You should see a confirmation that the AnywhereUSB (its IP address) has been added to the Connection List. The host computer will then immediately attempt to connect to the AnywhereUSB/2.

Note: If the IP address of the AnywhereUSB is already known, it’s not necessary to first discover it (using the “S” or “V” command).
