RN-WIFLYCR-UG
www.rovingnetworks.com Version 1.2r 4/30/13 page 114
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.
F.7 VERSION 2.21 07/11/2010
• The firmware checksum the image (and compare to the stored values in the file)
now before committing it to flash and updating the boot record after download. If
the checksum fails firmware prints “UPDATE FAILED” and deletes the image.
F.8 VERSION 2.20 06/14/2010
F.8.1 Fixes
• Passphrase is now accepts up to 64 chars. A bug introduced in 2.19 causes the
wlan passphrase to be truncated to 32 characters (making it impossible to enter a
32 byte HEX literal PSK).
• Fixed DHCP status when link to Access Point (AP) is lost. It was still reporting
DHCP OK. It is now cleared and new DHCP session will start once AP link is
reestablished).
• Fixed a bug whereby UDP receive becomes disabled (no packets are received) if
AP-LOST and then re-established.
• Improved handling of AP disconnect, and AP link lost due to linkmon timeout or
other disconnect.
• If TCP connection was active, connection could be in hung/incorrect state, and
once AP is regained in some cases this would not recover. This has been fixed in
this version. Refer section set ip flags <value> for more information.
• Added new setting to the UART mode set uart mode 0x10.
F.8.2 Features
• Disabled the auto-join feature when in command mode. Auto-join causes the
WiFly module to become unresponsive to $$$ or commands during the period
when auto-joining, when auto-joining is failing do to non-existent AP, making it
hard to process or interpret commands. Once command mode is exited, auto join
will re-enable.
• There are new levels of print out diagnostics that can be enabled/disable with the
sys print variable.
• Ability to add prefix to HTML client post, specifically the ability to append &id= and
&rtc= in the HTML message.
