Figure 3 Connecting to WiFi168
Connect the mobile phone or tablet to ‘WiFi168’ with ‘88888888’ as the default password. The
red LED will remain lit up once the connection is made. Should ‘WiFi168’ not be found on the
tablet or the mobile phone, please go to ‘Reset QK-W017’ (section 1.5 below) and follow the
steps to reset the module.
1.3 Ad hoc mode
The IEEE 802.11b/g wireless standard has two basic modes of operation, namely Ad hoc mode
and infrastructure mode (also called station mode). In Ad hoc mode, mobile terminals (phones,
tablets etc.) transmit directly to the controller (peer to peer). In infrastructure mode, mobile
terminals communicate through an access point (AP) such as a router, that serves as a bridge
to other networks (such as the Internet or LAN). The QK-W017 WiFi controller can support both
ad hoc and station modes.
Setting QK-W017 to operate in Ad hoc mode is quite straightforward.
Power off QK-W017.
Press and hold the ‘Reset’ button, then power up QK-W017. After the red LED has
been on for at least 3 seconds (display bars will flash), release the ‘Reset ’ button.
Wait about 15 seconds, the red LED will turn off while display keeps flashing with
bars.
Wait another 40 seconds, the red LED will turn on again and the display will show
the time (or 12:00 if the in-built rechargeable battery is flat).
