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 commands to the module. NOTE: For consistency, the command prompt response
<2.xx>
now also contains
\r\n
appended string when in this mode.
As of Version 2.12 9/17/2009
•
Fixed problem with some newer 802.11n - association attempts cause module to
crash/reboot. (Such as Linksys WRT160NL)
•
Fixed problem with send on match character, i.e. set comm match char. Match char is now
operational.
•
During an open TCP session, a second incoming connection would be accepted. Second
connection is now accepted but then immediately closed.
•
Hardware flow control is now supported. To enable, use the
“set uart flow 1”
command.
•
DHCP renew and rebind is fully supported. Previously, DHCP renew/rebind would update IP
settings, and if a TCP session was active it would enter a hung state. TCP connections now
survive a DHCP renew/rebind.
Features
•
TCP connection password
. This optional pass word is enabled with the command “set opt
pass <string>”, incoming connections will be challenged and the stored password must be
matched or the connection will be closed.
•
UART instant baudrate
The
set uart instant <rate>
command
immediately changes the
baudrate. This is useful when testing baudrate settings, or switching baudrate “on the fly”
remotely while connected over TCP.
•
Analog interface
commands
The “show q” command will now enable and show the digital
value of the analog interface pins. See section 14
As of Version 2.11 9/8/2009 – Limited release (please update to 2.12)
As of Version 2.10 8/14/2009
•
Added a 250ms guard band in parsing of $$$. The module now looks for three $$$, and only
three $$$ within a 250ms period with no additional characters following for 250 ms.
Do not
send \cr or \lf
after the $$$.
•
Fixed problem with UART dropping data. In cases with large data transfers (>100KB) the
UART would become over whelmed and drop data.
•
We no longer pass serial data received into the UART back over telnet when in remote
command mode
