3.2.2 Operation examples

3.2.2.3 Auto Connect

In the example below, the GS1500M module is configured to connect to an access point, the auto connect feature is 
enabled, and the settings are stored in a profile.  When re-started, the unit will connect to the access point whereupon 
serial data can be transferred to and from a remote IP address.

AT+NDHCP=1

   

 

 

 

DHCP enable

AT+WAUTO=0,<SSID>

   

 

 

Set auto wireless parameters (0=infrastructure).

AT+NAUTO=1,1,<Destination IP>,<Port>

  Set auto network parameters (TCP server).

ATC1

   

 

 

 

 

Set the auto connect mode

AT&W0

  

 

 

 

 

Save the configuration in profile 0

AT&Y0

  

 

 

 

 

Set to load profile 0 at start-up

At this point the GS1500M module should be restarted, either by pulling the RESET pin (WiFi1500CF pin 47) 
low or by removing and re-establishing power to the unit. The GS1500M will respond with its network settings 
upon successfully associating with the wireless network. Serial data can now be sent to and from the GS1500 
via the serial port. A telnet session or a simple TCP terminal can be opened at the client (destination IP) to 
demonstrate the sending and receiving of serial data. 
In order to terminate the Auto Connect session, enter a sequence of three ‘+’ (plus) symbols followed by one 
second of no data being entered. Following this the command mode will be available.

3.3 WiFi Module Firmware

The GS1500M WiFi module can be loaded with several versions of the S2W (Serial-to-WiFi) application firmware.  
Because of limited memory, certain features are only exclusively available in specific firmware loads.  By default, 
the module is loaded with the Web Provisioning firmware.  The table below illustrates the features available on the 
available firmware loads:
