Release Notes
20.1
Known problems
•
The UART does not support odd or even parity, only no parity is supported.
•
Flow control: RTS may fail to de-assert quickly enough for some high speed CPUs to
correctly stop sending data bytes. For high speed transfers at baudrates > 460800,
it is best to limit RX data to the maximum Ethernet frame (1460 bytes) and have a
protocol to acknowledge data is received by the remote host.
20.2
Current Firmware features and fixes
As of 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.
As of Version 2.20 06/14/2010
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
".
Features:
•
Disabled the auto-join feature when in command mode. Auto-join causes WiFly 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.
