# Precisioin about AT+WCHECK please

## Question

Asked by phil31 on 2015-09-17 in Wireless.

Dear,

in the description, you write :

[quote] Format:
AT+WCHECK=,,

```
Meaning: Check Wi-Fi status using Ping and Re-association with AP
```

It must be set as service mode in order to use Re-association function.
This function only exist later vision of F/W 1.0.3.5. [/quote]

i don’t find any 1.0.3.5 FW version !.. just 1.0.3.3 then 1.0.4.2 …

Hi phil31

As you know, You can just use 1.0.4.2 version for using AT+WCHECK
1.0.3.5 version is a private version because it is too unstable to release.

Thanks.

then when do you plan to switch 1.0.4.2 to “stable” ?

regards

Hi,

A 1.0.4.2 is not official firmware, it is a beta version. but you can only use AT+WCHECK at 1.0.4.2.

Thanks

Hello,

i’m using now 1.0.5.2

i set AT+WCHECK=10,5,3 (if i right understand, do automatically PING to the AP, each 10 seconds and reboot if failed answer)
i right receive the [OK], but i don’t see (wireshark) any PING request from my WIZFI device !

did i miss something please ?
