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 |
