4.4 Load Balance
The B4 tag supports access point load balance from firmware 1.2.0 onwards. Should the nearest
(strongest) access point reject tag association attempt because of the limit of simultaneous client
associations is reached, tag automatically searches the second strongest access point in the
network and associates to it. In case the second strongest access point is also unavailable (because
of the maximum number of simultaneous clients is reached there too), tag will continue searching
the third strongest for connection.
4.5 Smart Roaming
Normally tag stays associated to the same access point until the connection is almost lost. The
EkahauB4 tag (from firmware 1.2.0 onwards) keeps track of the signal strengths of the access
points. In case an access point with signal strenght stronger than 10 dBm or more than the one
tag is currently associated is found (from the same network), tag automatically switches to that
access point.
4.6 Resetting to Factory Settings
The tag can be reset to factory setting with the following button sequence . Note that you need to
connect the tag to the charger first to enable the reset sequence. Tag can be removed from the
charger, but the reset sequence must be initiated within 5 seconds after removal. During this time
tag will show continuos green light on the right LED.
