+LWIP SOCKET TCP TX/RX EXAMPLE
+
+Description:
+Example of TCP bidirectional transmission with use two threads for TCP tx/rx on one socket.
+Example 1 uses non-blocking recv and semaphore for TCP send/recv mutex
+Example 2 does not use any synchronization mechanism, but can only run correctly on lwip with TCPIP thread msg api patch
+
+Configuration:
+Modify SERVER_PORT in example_socket_tcp_trx.c for listen port
+
+[platform_opts.h]
+Run example 1 in example_socket_tcp_trx_1.c
+	#define CONFIG_EXAMPLE_SOCKET_TCP_TRX    1
+
+Run example 2 in example_socket_tcp_trx_2.c
+	#define CONFIG_EXAMPLE_SOCKET_TCP_TRX    2
+
+Execution:
+Can make automatical Wi-Fi connection when booting by using wlan fast connect example.
+A socket TCP trx example thread will be started automatically when booting.
+A TCP server will be started to wait for connection.
+Can use a TCP client connecting to this server to start a TCP bidirectional transmission
