# TCP Client example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
The application creates a TCP socket and tries to connect to the server with predefined IP address and port number. When a connection is successfully established, the application sends message and waits for the answer. After the server's reply, application prints received reply as ASCII text, waits for 2 seconds and sends another message.
|
||||
|
||||
## How to use example
|
||||
|
||||
In order to create TCP server that communicates with TCP Client example, choose one of the following options.
|
||||
|
||||
There are many host-side tools which can be used to interact with the UDP/TCP server/client.
|
||||
One command line tool is [netcat](http://netcat.sourceforge.net) which can send and receive many kinds of packets.
|
||||
Note: please replace `192.168.0.167 3333` with desired IPV4/IPV6 address (displayed in monitor console) and port number in the following command.
|
||||
|
||||
In addition to those tools, simple Python scripts can be found under sockets/scripts directory. Every script is designed to interact with one of the examples.
|
||||
|
||||
### TCP server using netcat
|
||||
```
|
||||
nc -l 192.168.0.167 3333
|
||||
```
|
||||
|
||||
### Python scripts
|
||||
Script example_test.py could be used as a counter part to the tcp-client project, ip protocol name (IPv4 or IPv6) shall be stated as argument. Example:
|
||||
|
||||
```
|
||||
python example_test.py IPv4
|
||||
```
|
||||
Note that this script is used in automated tests, as well, so the IDF test framework packages need to be imported;
|
||||
please add `$IDF_PATH/tools/ci/python_packages` to `PYTHONPATH`.
