hi dimas.
Of course, It is possible that you want to feature.
WizFi210 provide 2 modes and we called the Station mode and the Limited AP mode.
[quote]WizFi210 can operate in Limited AP Mode. WizFi210 doesn’t have any other Ethernet or WiFi interface for Uplink, so any device can’t access to Internet via WizFi210 which is operating as Limited AP. The lack of resources in WizFi210 restricts the number of devices able to join WizFi210.
However, Limited AP Mode of WizFi210 is useful when the mobile device, that has WiFi capability, directly connects to WizFi210 and communicate with it without any other Access Point.

After starting Limited AP and TCP Server of WizFi210, Android APP can communicate with WizFi210 as a TCP Client.
