In some cases flow control can get “stuck,” e.g., during a tcp_close or de-authentication in which the UART cannot transmit a TCP
packet and is holding it. Added a fix to attempt to clear the buffer.
In previous firmware, the associated status is always set even if no clients are joined. In version 2.45, the red LED correctly shows
the status if there are no devices joined. If you use ALTERNATE IO for associated, it is high if there are 1 or more clients, and low if
there are no clients.
In AP mode, the module supports 7 connections (DHCP and AP).
Fixed an issue with the ping command.
As of version 2.30 10/26/2011
Added support for incorrect WPA modes, namely WAPv1 with AES encryption and WPAv2 with TKIP encryption.
Added support for WEP shared mode.
Increased FTP filename size to 64 bytes.
Added a new reboot register in ad hoc parameters. This register is reserved for future development and should not be used.
Please leave it to default values.
Added a new debug register in the system parameters. This register is reserved for future development and should not be used.
Please leave it to default values.
As of version 2.27 09/08/2011
Added support for Wi-Fi Protected Setup (WPS) push button mode.
Added support for WEP64 encryption.
Added support for backup IP address.
Added a new TCPMODE register to control TCP connect timers, force DNS and remote configuration.
Added new bit in UART mode register (bit 5) in which replaces the <2.23>\r\n in console with the replace character.
Fixed the FTP file “put” mode so it over rides HTTP mode. In version 2.23 if HTTP protocol is set and/or option format is set, extra
data would be added to FTP put file data. This has been fixed in version 2.28.
Fixed a bug where if the TCP_CLIENT mode is set, the module would randomly attempt outgoing connections.
Fixed a bug in FTP data write mode whereby sometimes the *OPEN* status string came back over the UART before the file
transfer was actually ready. This fix also improves the speed of FTP open in write mode, such that the *OPEN* will be faster.
As of version 2.23 04/03/2011
Created new set of sensor commands:
set q sensor
<mask>
and
set q sensor
<value>
. Also, sensor power can now be configured
and applied either only when sampling of sensor inputs occur or at power up and removed upon power down and sleep.
Added a new FTP client mode to get and put files to a FTP server. Files retrieved from the server are sent over the UART and files
created from the UART are stored on the FTP server.
A new scan output format is implemented in addition to the default output format. This new microprocessor friendly format
makes string processing of the scan output very easy.
A new UART heartbeat feature is implemented to notify the embedded microprocessor of the state of the WiSnap module. The
heartbeat message is sent over the UART when the WiSnap module is in data mode and not connected to any remote host.
Fixed a bug in the
set uart instant
<value>
command where the WiSnap module would not return an AOK over telnet. Now when
this command is issued, it returns an AOK over telnet and does not exit command mode.
Enabled scanning for wireless networks remotely when in ad hoc mode. When the
scan
command is issued, ad hoc is temporarily
disabled and results of the scan are sent over telnet.
The behavior of the auto connect timer has changed.
Added the ability to set RTC from console.
Added a feature wherein the module can be put to sleep using GPIO8.
