# SSL example with certificate

## Question

Asked by ssekim on 2014-04-17 in Wireless.

I like to show how to connect ssl server with certificate using WizFi210.

Generally, to connect , you don’t need , and demand .
As a example, to connect , you need  which Apple issued to you.

Anyway, here is a example about using WizFi210.

Step1) Add Certificate File

> AT+TCERTDEL=rootca
> AT+TCERTDEL=usercert
> AT+TCERTDEL=userkey
> AT+TCERTADD=rootca,0,1273,0
> [OK]
> OK
> AT+TCERTADD=usercert,0,1413,0
> [OK]
> OK
> AT+TCERTADD=userkey,0,1191,0
> [OK]
> OK

Step2) AP Association and Set Time

[quote]AT+WD
[OK]
AT+NDHCP=1
[OK]
AT+WWPA=12345678
[OK]
AT+WA=WizFiDemoAP
IP SubNet Gateway
192.168.3.101: 255.255.255.0: 192.168.3.1
[OK]
AT+SETTIME=04/09/2013,13:11:11
[OK]

Step3) SSL Connect

[quote]AT+NCLOSEALL
[OK]
AT+NCTCP=17.172.xxx.xx,2195
[CONNECT 0]

[OK]
AT+SSLOPEN=0,rootca,usercert,userkey
[OK]
[/quote]

About <AT+TCERTDEL>, <AT+TCERTADD> and <AT+SSLOPEN> refer to the WizFi210 Programmer’s Guide.

About certificate file type and conversion, refer to the below site.
