Known Issues
WiSnap Module has trouble associating with some 802.11.n access points. The module will crash and reboot repeatedly. We
have seen this behavior with Linksys and Dlink router/access points. If you disable the .n capability on the router the module will
associated correctly.
Flow control is not functional.
Current Firmware Version 2.09 7/10/2009
Sleep mode was drawing 70uA instead of the expected 4uA due to an oscillator that was not disabled before going to sleep. Refer
to the WISNAP datasheet for the proper low-power hardware configuration.
Fixed closing of TCP port on TCP RESET. Previously the module was not handling remote TCP reset correctly and would disconnect
which resulted in a printout of ERR= -5, TCP port was not closed properly.
Fixed clearing and setting of strings in several
set
commands. In these cases the strings could be erased, but not reset.
-
set comm remote
-
set comm open
-
set comm close
-
set dns name
-
set dns backup
Removed extra character in UART output. Previously the module would insert an extra "\r" character when '\n' appears in data
stream.
Added the
get everything
(
get e
) command to display all configuration settings.
Fixed the alternate I/O functions to allow connection based on PIO5. The manual has been updated to include a much better
description of this functionality. See section 10.5.
As of firmware version 2.08 6/08/2009
Connecting out an IP address does not use the DNS and backup DNS if the connection to the primary IP address fails. Connecting
using DNS if the IP address if 0.
UART hardware flow control not yet functional.
TCP_NODELAY added as default. This improves performance as the stack no longer waits for each TCP packet to be ACK’ed, (since
many Microsoft systems only ACK every OTHER packet).
Set ip proto is now a bitmask. It is possible to have both UDP and TCP bits set. If TCP enabled, UART RX data will be forwarded via
TCP if a connection exists. Otherwise, data will forward over UDP (if UDP bit is set ).
As of firmware version 2.07 6/04/2009
set wlan antenna
< 0 or 1 >
command has been changed to
set wlan extant
<0 or 1 >
.
set wlan auth
<value>
command has been added.
set wlan hide
will hide the WEP key or WPA passkey. To unhide, you set key or passphrase again.
set ip proto 8
- TCP client mode, (no listen server) only outbound connections can be made.
Ad-hoc mode client associates properly.
You can now enter the WPA passkey after setting the SSID. Previously the pass key had to be entered first for the security hash to
be correctly created.
Auto join now stops after 3 retries.
show net
now displays the Wi-Fi TX rate, and correctly displays authenticated state and shows authentication mode that was
used.
ping h
will ping the stored host address. If no host address stored, will attempt to use the DNS hostname.
