Fixes
Improved performance of the UART receiver. UART is now reliable at up to 460Kpbs with RTS
•
flow control.
Features
Created UART data trigger mode, which will automatically make a TCP/HTTP connection based
•
on received UART data.
Added timestamping option to both UDP and TCP packets. 8 byte RTC counter is appended.
•
DHCP client now inserts the DEVICEID string into the HOST name when requesting a DHCP
•
lease. This string is displayed by most routers and DHCP servers in their lease tables.
show n n command returns the MAC Address of the Access Point currently associated.
•
get i a command returns only the IP address of the WiSnap.
•
show network added a response "Boot=<time in ms>" which displays the total time in
•
milliseconds that was required to be ready on the network (associate and get IP address).
This time is also added to the UDP broadcast packet at byte location 92.
Added a number of HTTP commands for posting data to a web server see Section 12.

As of Version 2.15 10/15/2009
Fixed a problem whereby the first UART RX character received on power up is received but
•
does not sent until receipt of 2nd character.
Fixed a problem with some APs that violate Wi-Fi specifications by not responding to WPA
•
authentication within 250ms.

When connected over TCP and the AP disappears or WiSnap loses association the WiSnap will
•
now closes the connection. The *CLOS* response will now appear when the connection is
terminated by the WiSnap. NOTE: This may require the use of the set comm idle xx setting
to monitor the TCP connection, and force a TCP disconnect when no data is flowing due to lost
association.
Features
Link monitor The command set wlan linkmon x is now used to monitor the state of the
•
association to the AP.
WiSnap declares "AP is lost" sets the interface to down state, and enters the association
process. Previously the WiSnap would not detect that the AP association was lost until the
AP became available again, or the WiSnap was power cycled or rebooted.
AD-HOC mode The command set ad-hoc probe x is now used to set a threshold for the
•
number of consecutive missed probe responses allowed before declaring "AD-HOC is Lost"
and setting the network interface to be down.
set ad-hoc probe 0 will disable this function. Some Ad-hoc stations do not reliably respond
to probes and so this value higher avoids intermittent loss of connectivity.
