Sending Start Request
You must input the board IP address that was displayed in the serial monitor after the connection. The script connects to the board
and sends a request to the TCP server so that it will set the FICA bit and reset the board into the OTA update mode.
When the board is in the OTA update mode, the transfer starts:

Upon completion, the SLN-LOCAL2-IOT kit restarts itself automatically and switches over to the new application bank, running
the new application that was just flashed.
The OTA update sets the FICA bit and triggers the board by running the fwupdate_client.py script, whereas the OTW update must
set the FICA bit using the updateotw shell command. For the OTW, make sure that the COM_PORT matches the target com
port address.
