I have checked the USB configuration tool separately on the Core RTU device, and it is working. It needs to be verified again after the code merge.

While using the USB Device Configuration Software, when the protocol is changed from RTU to TCP in the Modbus Config section and the Update button is clicked, the system displays a "No response received from the device" error message, and the configuration change is not applied.

  1. No response popup in the USB tool occurs when the ack is not sent or even if ack didn't reach to the tool as per the time intervals maintained in the tool so some time time period has been increased in the USB tool application. Even if that message is popping up the packet will be updated.

  2. I'm handing over this for testing to chetan.
