Done
```
## Example1: TCP/UDP server and client
### Step 1 Configure the project
```bash
idf.py menuconfig
```
Enable the operation: Example Configuration -> Enable custom command in ot-cli -> Enable openthread tcp/udp socket
### Step 2 Build, Flash, and Run
You need to prepare two ESP devices each connected to a 15.4 RCP and flashed with this example.
```
idf.py -p PORT flash monitor
```
### Step 3 Set up network
On the first device, run:
```bash
> extaddr 166e0a0000000001
Done
> dataset channel 17
Done
> dataset panid 0xface
Done
> dataset extpanid 000db80000000000
Done
> dataset networkname GRL
Done
> dataset masterkey 00112233445566778899aabbccddeeff
Done
> dataset meshlocalprefix FD00:0DB8:0000:0000::
Done
> dataset pskc 00000000000000000000000000000000
Done
> dataset activetimestamp 1
Done
> dataset commit active
Done
> ifconfig up
Done
> thread start
Done
# After some seconds
> state
leader
Done
```
Now the first device has formed a Thread network, on the second device run:
```bash
> extaddr 166e0a0000000002
Done
> dataset channel 17
Done
> dataset panid 0xface
Done
> dataset extpanid 000db80000000000
Done
> dataset networkname GRL
Done
> dataset masterkey 00112233445566778899aabbccddeeff
Done
> dataset meshlocalprefix FD00:0DB8:0000:0000::
Done
> dataset pskc 00000000000000000000000000000000
Done
> dataset activetimestamp 1
Done
> dataset commit active
Done
> ifconfig up
Done
> thread start
Done
# After some seconds
> state
router # child is also a valid state
Done
```
Now the second device has joined the Thread network and acting as a router (or a child).
### Step 4 Set up tcp/udp socket server and client
In leader device, run this command in command line shell.
```bash
# for setup a tcp server
> tcpsockserver
# for setup an udp server
> udpsockserver
```
Then run this command to get the leader IPv6 address.
```bash
> ipaddr
fd00:db8:0:0:0:ff:fe00:fc00
fd00:db8:0:0:0:ff:fe00:ac00
fd00:db8:0:0:284a:cb4a:cb3b:2a42
fe80:0:0:0:146e:a00:0:1
```
In router device, run this command to set up a socket client in command line shell.
```bash
# for setup a tcp client
> tcpsockclient fd00:db8:0:0:284a:cb4a:cb3b:2a42
# for setup an udp client
> udpsockclient fd00:db8:0:0:284a:cb4a:cb3b:2a42
```
You will get
```bash
# in leader device
> tcpsockserver
