softap.captive_portal_enabled

Abbreviation

so v

Access

get/set

Description

Captive portal is optional during websetup and for the softap.

During web setup if if softap.captive_portal_enabled is true, when the HTTP server receives a request for one of the following:

/generate_204 - Android
/hotspot-detect.html - iOS
/ncsi.txt - Windows

then Gecko OS automatically returns the HTTP response:

HTTP/1.1 302 Redirect\r\n
Location: http://<server domain>/\r\n\r\n

This notification redirects the user to the root HTTP server webpage.

The DNS server AND HTTP server must be configured to run on the softap interface for this feature to work.

Note: if captive portal is NOT enabled for the softap, then when a request for one of the above resources is received, the HTTP server automatically returns:

HTTP/1.1 204 Ok\r\n\r\n

This makes it appear as if the softap has internet access. This allows for a better user experience as:

A mobile will automatically reconnect to the softap
No 'no internet' notification is displayed to the user

The DNS server automatically resolves the following domains to enable captive portal:

captive.apple.com
www.msftconnecttest.com
www.msftncsi.com
connectivitycheck.gstatic.com
clients3.google.com

softap.channel

Abbreviation

so c

Access

get/set

Description

The SoftAP channel.

If a WLAN interface is already active, the value of softap.channel is ignored, since the WLAN interface has channel set priority.

If WLAN interface is not active, and softap.channel is 0, SoftAP starts on the least busy of channels 1, 6 and 11.

See Wi-Fi Interface, SoftAP Interface.

softap.max_clients

Abbreviation

so m

Access

get/set

Description

Limit the number of clients that may connect to the SoftAP interface.

Note: A maximum of 4 clients can send packets to the device.

Note: Due to a hardware limitation, more than softap.max_clients are able to associate to the soft AP, however the client's packets are dropped. Thus clients are able to monitor soft AP network traffic, but are not able to send packets to the device.

Arguments

<clients>

where <clients> is an integer ranging from 1 to 4.

Default

4.

A maximum of 4 clients can send packets to the device.

Platforms

softap.static.gateway

Abbreviation

so s g

Access

get/set

Description

Determines the SoftAP interface's gateway advertised during a DHCP response. This allows the SoftAP gateway to be set independently of the softap.static.ip. If softap.static.gateway is set to 0.0.0.0, then use the softap.static.ip setting as the gateway.

This setting is only used if softap.dhcp_server.enabled = true. This setting is used in the DHCP response Router option (and optionally in the DNS Server option).

Use Cases

softap.static.gateway	softap.dns_server.enabled	Router DHCP response option	DNS Server DHCP response option
`0.0.0.0`	`true`	`softap.static.ip`	`softap.static.ip`
valid and not `0.0.0.0`	`true`	`softap.static.gateway`	`softap.static.gateway`, `softap.static.ip`
valid and not `0.0.0.0`	`false`	`softap.static.gateway`	`softap.static.gateway`
`255.255.255.255`	`true` or `false`	Not advertised	Not advertised

softap.static.ip

Abbreviation

so s i

Access

get/set

Description

The IP address used for the softap network interface. The netmask is 255.255.255.0.

The softAP gateway depends on the softap.static.gateway setting. If softap.static.gateway is 0.0.0.0, the gateway is set to softap.static.ip.

Note: The softap.static.ip settings are also used for web setup.

See Wi-Fi Interface, SoftAP Interface.

Arguments

<IP address>

Default

10.10.10.1

Platforms

AMW007

Get example

> get so s i
R000013
10.10.10.1

Set example

> set so s i 192.168.10.1
R000008
Set OK

softap.static.netmask

Abbreviation

so s m

Access

get/set

Description

Determines the range of IP addresses offered by the Soft AP.

For example, a netmask of 255.255.255.0 gives a range of 254 IP addresses.

Some platforms, such as Windows 8, send ARP (Address Resolution Protocol) packets to all available IP addresses, which can overload the module WL chip.

The work-around is to set a default network mask pf 255.255.255.240, so valid IPs are limited to the range x.x.x.1-7. Consequently only 8 ARP packets are sent.

Arguments

<netmask address>

Default

255.255.255.240

Platforms

AMW007

Get example

> get so s m
R000017
255.255.255.240

Set example

> set so s m 255.255.255.0
R000008
Set OK
