I'm hoping someone can help. I have searched and found this topic mentioned several times and I have tried the solutions offered but still no luck. I have done both a firmware update and updated to the latest version of ARC. When trying to connect I get the following message: This device is not an EZ-B. Please follow the online tutorials on the EZ-Robot website. I have tried re-installing/repairing ARC. I currently connect my developer kit through the router. I have reset back to factory settings and connect directly to the ez-b v4 but still get the same issue. I have tried using EZ-B firmware update V4 where I get the following: attempting connection on 192.168.0.53:23 connected to 192.168.0.53:23 Reports 69 and then in a separate window I get the This device is not an EZ-B error. When I click on the Scan for EZ-B v4 it finds two options: EZ-B v4.x/2(192.168.0.53:23)(Type: EZ-B v4.x/2) EZ-B v4.x/2(192.168.0.53:24)(Type: Camera)

If I select the top option and select connect I get the This device is not an EZ-B error and this dialog in green and black at the bottom of the screen:

EZB 0: EZB 1: EZB 2: EZB 3: EZB 4: Windows version: Microsoft Windows NT 10.0.15063.0 Screen Resolution: 1366x768 (96x96 dpi) Version: 2018.05.01.00 Attempting connection on 192.168.0.53:23 Comm Err: System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at EZ_B.EZB.FwDTDUYvh5(Int32 , Byte[] cmdData) BbytesToExpect: 1 U Received: 0 Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.pvK1h1uI5L() at EZ_B.EZB.Connect(String hostname, Int32 baudRate) Disconnected

If I select the camera option it says connect to EZ-B, not a camera. Batteries are fully charged but don't understand why it is no longer communicating with the PC?
