timeout in ms for a join now also applies to the WPA timeout. The default is now 1000ms or 1
second. Note: some APs require up to 1500ms to respond.
•
When connected over TCP and the AP disappears or WiFly loses association the WiFly will now
closes the connection. The *CLOS* response will now appear when the connection is terminated by
the WIFly. NOTE: This may require the use of the
set comm idle xx
setting to monitor the TCP
connection, and force a TCP disconnect when no data is flowing due to lost association.
Features
•
Link monitor
The command
set wlan linkmon x
is now used to monitor the state of the association
to the AP. The AP is scanned once per second, and if x consecutive scans fail, the WiFly declares
“AP is lost” sets the interface to down state, and enters the association process. Previously the
WiFly would not detect that the AP association was lost until the AP became available again, or the
WiFly was power cycled or rebooted.
•
ADHOC mode
The command
set adhoc probe x
is now used to set a threshold for the number of
consecutive missed probe responses allowed before declaring “ADHOC is Lost” and setting the
network interface to be down. Default is 5 probes. A setting of
set adhoc probe 0
will disable this function. Some Adhoc stations do not reliably respond to
probes and so this value higher avoids intermittent loss of connectivity.
•
DHCP cache
The
set ip dhcp 3
command is now used to enable DHCP address caching. Once
caching is turned on, the initial DHCP settings are stored in NVRAM. This is most useful in battery
systems, when using the sleep mode. Upon waking from sleep, as long as the DHCP lease time is
still valid and the WiFly is associated to the same AP, DHCP caching does not survive a power
cycle or usage of the hardware reset pin.
•
ARP table cache
The
set ip flags 0x20
command is now used to enable ARP table caching. Once
caching is turned on, any ARP table settings are backed up to NVRAM before sleep. Upon waking
from sleep, the ARP cache is loaded. ARP table caching does not survive a power cycle or usage of
the hardware reset pin.
•
DNS host address cache.
The
set ip flags 0x10
command enables DHCP address caching. Once
caching is turned on, the initial DHCP settings are stored in NVRAM. This is most useful in battery
systems, when using the sleep mode. Upon waking from sleep, as long as the DHCP lease time is
valid and the WiFly is associated to the same AP, DNS caching does not survive a power cycle or
usage of the hardware reset pin.
•
UART break detect enables sleep.
The command
set uart mode 8
enables break detection on the
UART RX pin. Once Break is detected (a consistent low value on RX pin) ,WiFly waits for the
UART RX pin to return to a high value before going to sleep.
•
UART NOECHO mode.
The command
set uart mode 1
is now used to disable echoing of RX
chars while in command mode. This is useful
when embedded controllers are used to send
