wlan.bssid

Abbreviation

wl b

Access

get/set

Description

Specify the BSSID for the WLAN.

When wlan.bssid is set, Gecko OS attempts to associate with the network via the access point with the specified BSSID, regardless of the wlan.ssid setting. This allows connecting to hidden networks.

The wlan.passkey must be provided.

The wlan.ssid cannot be empty. Setting wlan.ssid clears wlan.bssid , so set wlan.ssid first, then set wlan.bssid . For example:

Gecko OS Commands Description 
set wlan.ssid my_network
set wlan.bssid 11:22:33:44:55:66
set wlan.passkey my_password
network_up

first set the SSID
next set the BSSID
set the network's password (if required)
connect to the network

Note : On joining a WLAN, if the WLAN SSID is advertised, it replaces the value of wlan.ssid .

To disable wlan.bssid , set the value to 00:00:00:00:00:00 or set wlan.ssid to clear it.

wlan.dhcp.cache_enabled

Abbreviation

wl d c

Access

get/set

Description

When DHCP caching is enabled, the received DHCP IP address and corresponding lease time is cached to RAM. When the device is rebooted via the reboot command, the RAM cache and corresponding timestamp is saved to NVM.

Upon rebooting the saved DHCP IP is restored and the lease time is updated with the amount of time that has elapsed since it was last stored. DHCP IP caching can save a considerable amount of time when re-connecting to the network as the full DHCP sequence is skipped (assuming there is enough time left on the DHCP lease).

wlan.join.retries

Abbreviation

wl j r

Access

get/set

Description

Specifies the maximum number of attempts to join a WLAN network after issuing the network_up command (or any other command requiring network access when the network is down).

See Procedure for Joining a WLAN Network .

If the network_down command is issued while attempting to join a network, the subsequent attempts are canceled.

Note :

The wlan.join.retries variable is separate from the wlan.auto_join.retries variable.

If wlan.auto_join.retries > 0 , then the total number of retries is calculated by the multiplication of wlan.join.retries with wlan.auto_join.retries .

Note : If wlan.join.retries is set to 1 , the device attempts to connect only once. If the device has cached network details, and these details are no longer true due to network changes, the device fails to connect and does not attempt to connect again. Set wlan.join.retries to 2 or more to avoid this problem. See The Network Up Sequence .
