How do I send data between two Wi-Fi modules configured in ad hoc mode (point to point connection)

Latest Update: January 19, 2012 11:37pm

In order to send data between two Roving Networks' devices configured in ad hoc mode, the following configuration is recommended:

Module #1:

set wlan join 4                             // Creates a software adhoc network
set wlan channel 1                     // Specify the channel on which ad hoc networks is created
set wlan ssid cable                    // Specify the network name (SSID)
set ip dhcp 0                               // Disable DHCP server to enable static IP
set ip address 169.254.1.1      // Assign a static IP to the module
set ip netmask 255.255.0.0     // Set the subnet mask
save                                             // Save configuration in the config file
reboot                                          // Reboots the module so that the stored parameters take effect

Module #2:

set wlan join 4                           
set wlan channel 1
set wlan ssid cable
set ip dhcp 0
set ip address 169.254.1.2
set ip netmask 255.255.0.0
set ip host 169.254.1.1             // Specifys the IP address of the other module to connect 

set ip remote 2000                    // Sets the port number of the other module to connect to

set sys auto 2                             // Enables automatic opening of TCP connection to Module #1

save                                             // Saves the configuration in config file

reboot                                          //Reboots the module so that the stored parameters take effect

 

At this point in time, Module #2 should be able to automatically open a TCP connection to Module #1. You should see a *OPEN* on the UART indicating that TCP connection has been established.
