5.1.2.1 Point-to-Point Auto connection operation mode
Besides of the traditional dial-up connection above, a pair of WINC 900A can be operated in
auto connection mode in order to establish a point-to-point permanent wireless linkage.
In the point-to-point auto connection operation, one of the two units will play a roll as Master
unit, the user must issue the following AT commands to specify the address of the slave unit
and to enable the auto connection operation at the Master unit.
AT commands issued at the Master unit to specify the address of the slave unit and to enable the
auto connection function are :
AT~Axxxxxxx
(“xxxxxxx” above stands for the 7 digit address of the slave unit)
AT&!1
(to enable the auto connection function)
After initiating the auto connection operation, the Master unit will issue the connection request
to the specified slave unit, establish connection, and go into connection mode. The Master unit
will automatically recover the established wireless connection after the drop of linkage resulting
from power outage or interference. Before issuing AT commands for configuration change or
terminating the auto-connection function, users must issue the escape sequence, holding the
“Shift” key and pressing “+” key 3 times, to return to the command mode.
