Release Notes PN 93000530_F3 Digi Connect Wi-ME 82000977_F3 EOS June 6, 2005 INTRODUCTION This is a production release of firmware for the Digi Connect Wi-ME. The Digi Connect Wi-ME embedded device server web and network enables products easily without the complexities of extensive hardware and software integration. The Digi Connect Wi-ME provides powerful "plug-and-play", customizable and future-safe features, and performance in one of the smallest solutions available. SUPPORTED PRODUCTS Digi Connect Wi-ME ENHANCEMENTS Added user configurable option to set the wireless transmit power. Added Poland and the Czech Republic to the list of supported wireless country codes. BUG FIXES Fixed authentication issues with default web interface files. Fixed HTTP 400 Bad Request status seen when the password field was cleared on wireless client certificate uploads. The stored client and trusted certificates were not getting deleted in all cases. Prevent transmit gaps on small amounts of data. Limit 802.11 transmit rate to 1 and 2 mbps on Channel 14 because the hardware is not certified for higher rates. Limit the wireless transmit power to 12 when Japan is the configured country code. Certificate files are now uploaded to a hidden directory - this means any certificates that were used with the F1 binary will need to be uploaded again. KNOWN ISSUES The current hardware doesn't allow user to set less than 6 dBm wireless transmit power. With encryption set to AES, serial throughput will be lower than usual It is not currently possible to configure the escape characters used by client applications (connect, telnet, and rlogin). If the standard web service (HTTP) is disabled, the encrypted web service (HTTPS) stops operating. They will be made independently selectable in a future release. In order to clear the persistent storage from the CLI one can execute the "boot action=factory" command. The only web accessible method for clearing the storage is available via the reset functionality in the administrative pages at "admin/factory_defaults.htm". When attempting to replace files in the file system, simply overwrite the existing version of the file rather than deleting the file first. Attempting to delete the file first defeats the internal file versioning maintained by the firmware, and can confuse your browser's cache. Microsoft Internet Explorer 6 Service Pack 1 (SP1) has a known problem where it displays the error message "Internet Explorer Cannot Open" when you use an HTTPS URL to access this Digi product. The following Microsoft article explains the problem: http://support.microsoft.com/default.aspx?kbid=812935 Due to certain browsers and their settings, the web interface may not appear proper after after a firmware upgrade. If this occurs, please clear your browser's cache or delete your browser's temporary files. When attempting to upload certificate files using Firefox, seeing an intermittent error: "Unable to upload file: invalid path (Code: -40)" CONNECTING TO THE WIRELESS DEVICE The device can only be configured over the wireless link with an access point. In order to establish a wireless link the access point must have authentication and encryption disabled. Furthermore to ensure that the Connect Wi-ME establishes a link with the correct access point the access point should use the SSID of "Connect". By factory default our device scans through each wireless channel and generates a list of access points. It then associates with the access point with the strongest signal strength. However it will choose to associate with an access point with SSID of "Connect" over another access point that has a different SSID regardless of which access point has the stronger signal strength. When the device successfully associates with an access point its link LED will go solid. CONFIGURING THE WIRELESS DEVICE Once link has been established the device can be discovered using the "Digi Device Discovery" tool. Using this tool you can find the device and if necessary assign it an IP address. Once the IP address has been determined or established you can configure it using a web browser or telnet. If at any point the device is configured in a state that it can no longer be connected to, a factory reset can be done as described below in the "RESETTING THE UNIT" section. IP ASSIGNMENT NOTES The Digi Connect Wi-ME supports three IP assignment methods: * Static IP address * DHCP * Auto-IP If a static address is enabled, it will be used. If a static address is not enabled, and DHCP is enabled, the unit will use an address supplied by a DHCP server regardless of the state of Auto-IP configuration. If a static address is not enabled, and Auto-IP is enabled, it will be used to generate an address ONLY if DHCP is disabled, or if DHCP is enabled and a DHCP server has not responded to the DHCP query. If both are enabled, Auto-IP has assigned an address, and then a DHCP server responds, the Auto-IP address will be discarded and the DHCP address will be used. RESETTING THE UNIT The Digi Connect Wi-ME firmware has the ability for an embedded host system to both soft reset the unit as well as reset the unit to its factory defaults. Both functions may be invoked via manipulation of pin 20 on the Wi-ME module's header: * If the module is running (i.e. more than a few seconds after power on), holding pin 20 low for a second and then raising it will soft reset the unit * If pin 20 is held low for more than 10 seconds from the power on or release from hard reset of the unit, and then raised, it will reset the unit to its factory default state In either case, the action takes effect when the pin is raised (reset released). On the development board placing a jumper across pins 2 and 3 of jumper block P12 will cause pin 20 to be low. ADDITIONAL INFORMATION The new "set wireless transmit power" feature is not currently documented in the CLI and RCI manuals. In the CLI, it is added as a parameter on the set/show wlan command. In the "show wlan" command, it is displayed as: txpower : 6dbm and in the "set wlan" it has the following syntax: set wlan [txpower={16dbm | 14dbm | 12dbm | 10dbm | 8dbm | 6dbm}] In the RCI, it is part of the data group and its field is . The following values are valid for the txpower field: 16dbm, 14dbm, 12dbm, 10dbm, 8dbm, and 6dbm. The configuration save and restore tools will save every configurable parameter (including IP configuration) except for some related to password authentication. ENABLING THE WEB USER INTERFACE The embedded web user interface is ALWAYS available at the following URL: http://ip-address-of-device/home.htm It is also available as the default configuration interface at the following URL: http://ip-address-of-device If your device contains the Java configuration applet it can be executed by connecting to the embedded web user interface and clicking the "Launch" button on the "Home" page under the "User Interfaces". It can be made to be the default configuration interface by clicking the "Set as Default" button on the same page. The Java Configuration Applet may remain in the unit's file system without affecting the embedded web user interface. If you would like to use the Java Configuration Applet as an alternative, simply upload the index.htm file as a file with an alternate name (e.g. applet.htm). You would then be able to use the Java Configuration Applet by accessing the following URL: http://ip-address-of-device/applet.htm HISTORY 82000977_F1 Added support for multiple users and permissions Added support for TCP Keepalive Added support for remote management using the Connectware server Added support for DHCP Option 12 Added support for ADDP V2 Added support for OEM Customization WPA enhancements: - TLS, TTLS, and PEAP authentication methods - CHAP, GTC, MD5, MSCHAP, MSCHAPv2, OTP, and PAP authentication methods for use with TTLS and PEAP - Client certificates for use with TLS - Verification of server certificates - CCMP (AES) encryption Wireless networking enhancements: - Separate authentication and encryption settings - WEP with 802.1x authentication - Cisco LEAP - Settings for short preamble and antenna diversity (Wi-EM only) - Display current authentication, encryption, and network statistics Added support for exposing wireless statistics via RCI Restructured the Web UI into HTML 4.01 compliance Enabled the CLI PING command on this device Added the option of enabling the CLI on a serial port Fixed several issues with alarms including one problem where snmptraps were continuely being sent out Fixed several problems with backup/restore Fixed bug with reporting incorrect ICMP stats Added wireless country support and approval for many European countries and Japan WEP keys are now checked for length Fixed a problem where network links would not come up when connecting to a Leadership Network Hub Fixed several RCI memory leaks Added support for RTS toggle predelay and postdelay On receiving an RCI reboot command, the unit would give an incorrect response Fixed a problem where using raw sockets resulted in lost serial data when sending a NULL character Fixed a problem where RCI over serial would stop accepting data Fixed a problem where the agent IP field in an SNMP trap was incorrect if the unit received its IP address via DHCP Fixed a problem where changing the destination IP address for SNMP traps required a reboot to become effective 82000977_E1 Fixed issue with wireless failing to work properly at cold temperatures.
