I managed to get in touch.
I took an example: TCPClient_MultiThread
In it I changed the IP to “127.0.0.2”

local socket = 0
local err = 0
local ip = "127.0.0.2"

local tcpData = nil

while true do
	::create_server::
	err, socket = TCPCreate(false, ip, 8000)
	if err ~= 0 then
		print("Failed to create socket, re-connecting")
		Sleep(1000)
		goto create_server
	end
	err = TCPStart(socket, 0)
	if err ~= 0 then
		print("Failed to start server, re-connecting")
		TCPDestroy(socket)
		Sleep(1000)
		goto create_server
	end
	TCPWrite(socket,"start")
	while true do
		err, tcpData = TCPRead(socket,0)
		if err ~= 0 then
			print("Failed to read data, re-connecting")
				TCPDestroy(socket)
				Sleep(1000)
			break
		end
		positionCmd =tcpData.buf
	end
end
