|

## 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
|
||||
