• UART NOECHO mode. The command set uart mode 1 is now used to disable echoing of RX
chars while in command mode. This is usefulwhen 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 baudrateTheset uart instant <rate> commandimmediately changes the baudrate.
This is useful when testing baudrate settings, or switching baudrate “on the fly” remotely while
connected over TCP.
• Analog interfacecommandsThe “show q” command will now enable and show the digital value of
the analog interface pins. See section 16
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
$$$ within a 250ms period with no additional characters following for 250 ms.Do not send \cr or
\lfafter the $$$.
• Fixed problem with UART dropping data. In cases with large data transfers (>100KB) the UART
would become over whelmed and drop data.
