one direction wireless communication

Hi,
I want to send data for many wifi station to control them and don't need any reply from them.In each station I used this wifi module:
ESP8266-WIFI-sending-and-receiving-wireless
and for controller I want to use this wifi:
TP-LINK-TL-WA7210N-150Mbps-Wireless-Outdoor-Long-Range-CPE-150Mbs-2-4Ghz-WIFI-Signal-Booster
The problem is that "ESP8266" can't connect to "TP-LINK-TL-WA7210N" because them distance!
If I don't use any password for "TP-LINK-TL-WA7210N" and hide SSID can "ESP8266" connect, and get data?
Thanks

You would probably need conventional basic transmitter and receiver setups that don't require any bidirectional communication.
