SMU is the safest way to set it.

# smu_cli set tx-max-bg 6

# smu_cli get tx-max-bg

    Reg Domain:  WW

    BG Antenna Adj: 3 dB

    A  Antenna Adj: 0 dB

Remember the  value is in ½ db increments so you need to use 6 to get 3 dBm. 


Also fw_setenv is able to set it as well.

Where can I find the SDK for the Enterprise Wi-Fi Radios? If there is no SDK available for download in the product's Software Downloads section then the SDK will be in the release .zip folder.  

 

 

1) The SD host controller driver (their driver, not ours) detects that a device is on the SDIO bus and signals the SD bus driver (a Microsoft driver) 2) The SD bus driver enumerates the card to determine what device it is and what client driver needs to be loaded.  The bus driver does this at a low clock frequency because it doesn?t yet know what bus speed the client device can support.  Note that the host controller driver is the one that actually performs all accesses to the card as it is the one that manages the actual SDIO controller hardware on the host platform.  The bus driver is accessing the card via the host controller driver. 3) The SD bus driver determines that our driver is the ?client driver? registered for the card by reading the vendor/product IDs from the card and looking up that information in the registry.  Our driver is registered for that combination of VID/PID. 4) The bus driver loads the client driver, which in this case is our driver. 5) The client driver continues initialization, which includes accessing the card itself by making calls to the SD bus driver which passes those calls on to the host controller driver which implements the actual card access via the host controller itself in the host CPU.  It?s important to note that the client driver (us) only requests that a card access be made; it is the host controller driver that implements the access via the host controller on the host CPU.   6) Very early in the initialization sequence the client driver (us) makes a call to the bus driver to configure the bus speed, bus width etc.  The speed is the lower of what the card supports and what the host controller supports on that slot.  From that point on, all accesses are occurring at a much higher bus speed. 7) The card continues initialization, which includes downloading the firmware and then enabling interrupts.  From this point on, interrupts have to be working for the card to function properly.

 

 

By default, it will show annoSUMMIT as outer ID to protect the ID not showing in public. If really need to show the real ID in outer ID, then need to add semicolon (;) at the end of ID configuration to make it happen.

 

 

No, Laird Linux package doesn't support uClibc in 45 and 50 series.

 

 

Auto profile is to roam among multiple profiles you add into the auto profile list. You can add this by LCM or by registry as below. Auto Profile Registry Setting You can enable Auto Profile from the registry. Key autoProfile Path HKLM\Comm\SDCCF10G1\Parms\Configs\GlobalConfig   Note: The HKLM\Comm\SDCCF10G1\Parms\Configs\... path is the same for all radios. Type DWORD Config01 is (by default) the default profile and cannot be used for auto profile. It must be set to 0. For example, if you want to automatically connect to Config02, Config05, and Config10, that would equal 10000100101 Convert that number to decimal which is 1061. The number 1061 would be entered as the value for the autoProfile key. 

 

 

Roaming cannot be disabled. You may set the roam trigger to the lowest RSSI value in the list which will cause the client to remain connected without scanning to roam until this very low RSSI is measured. However, beacon lost and some other situations may also trigger roam scan.  On loss of association the client disregards the roam trigger, delta, and period and immediately begins scanning to re-associate as quickly as is possible. Roam Trigger The signal strength (RSSI) (in dBm) at which the radio scans for an access point with a better signal strength. When scanning for a different access point, the radio looks for one with a RSSI at the indicated roam delta dBm level or stronger. Key Roam Trigger Path HKLM\Comm\SDCCF10G1\Parms\Configs\GlobalConfig\RoamTrigger   Note: The HKLM\Comm\SDCCF10G1\Parms\Configs\... path is the same for all radios. Value -50 (0x32) -55 (0x37) -60 (0x3c) -65 (0x41) -70 (0x46) -75 (0x4b) -80 (0x50) -85 (0x55) or Custom Default -70 Type DWORD

 

 

WMM APSD stands for Wi-Fi Multimedia (WMM) Automatic Power Save Delivery. It is basically a feature mode that allows your mobile devices to save more battery while connected to your wifi network. So to use APSD, WMEenabled must be set. WMM Use of Wi-Fi Multimedia Extensions, also known as WMM. Key WMM Path HKLM\Comm\SDCCF10G1\Parms\Configs\GlobalConfig\WME   Note: The HKLM\Comm\SDCCF10G1\Parms\Configs\... path is the same for all radios. Value (0) On (1) Off  

 

 

Yes, we support certificate valid date checking, but need to enable bit 2 in suppInfo. unsignedlongsuppInfo -  Meaning: Turn on or off other protocols. -  Value: bit 0 is Summit FIPS on/off; bit 1 is reserved; bit 2 is CA cert date-check enable; bit 3  is pre 2014 WPA1 operation 

 

 

We will check if the CA cert is out of date. If yes, have error code during the authentication process.

 

 

The value that is in the CF10G_STATUS driverVersion field from SDK is not the complete, full driver version.  It contains the A value in the upper 16 bits, the B value in the next 8 bits and the C value in the lowest 8 bits. In addition, there are some flags that are OR?ed in to the lower 16 bits.  Overall, it is nearly useless as a driver version field but due to backwards combability issues so can?t be changed at this point. The driver writes its full version to the registry at boot as below.  This is where the LCM gets the driver version,. [HKLM\Comm\SDCCF10G1\Parms]     ?DriverFullVersion?  

 

 

The responsibility for providing the QDID for a host system is with the provider of the stack that is used on that system. If for instance the host system uses a module that requires the Bluetooth stack to run on that system (e.g. Lairds Sterling-LWB in a Linux platform) the QDID must be provided by the stack vendor who's stack is running on that Linux platform. Challenges might occur when an open-source, community based stack is used. If a module with integrated stack us used (e.g. Lairds BL652) the QDID is provided by the module vendor.  

 

 

The ECCN for the radios listed, which comprise the "Summit" line of Wi-Fi radios, is 5A002.

All this can be controlled through standard Linux commands/programs like ?iw?, ?hostapd?, ?wpa_supplicant?, ?wpa_cli?, etc.

Ezurio provides 3D files (STEP) files for most but not all of it's modules.  Based on the nature of the information in the files, in most cases Laird requires a login to access these files as well as layout files and software/firmware downloads.  As such, for most modules, the 3D files are found under the Software Downloads tab of the product page.  The page offers a credentials request link for customers who need credentials.  In most cases, the credentials are provided via return email within about 10 minutes. Please contact support if you have any additional questions or have any issues accessing our downloads.

We only recommend reflowing our modules once as it can damage the module and void the warranty.

We highly do not recommend conformal coating the radio module. If you plan on encapsulating the radio module in a potting compound or conformal coating, you must assure that the compound in liquid or solid form does not enter under the shield where there are sensitive RF components. Some of the capacitive and inductance values are as low (pF and nH) and could be sensitive to contacting materials such as potting compounds. There are potting compounds and conformal coatings which have very good dielectric constants and are suitable for 2.4 GHz potting applications, however, when you apply any of these, they were not accounted for in the circuit design and might reduce performance of the device (or all together cause it not to function).  You should run tests on their particular potting compound and evaluate radio's performance and range.  Also, it's worth mentioning that applying any compound, conformal coating or potting directly to the module WILL void the warranty. If your application requires 100% sealing of the radio module, there is a way to do this very successfully without impacting the module performance. Simply place the module on your PCB. Place a plastic cover over the module (like a hat), make the cover large enough to cover the whole module. Apply glue around the bottom perimeter of the cover where it sits on the PCB. This allows the module to function in free air-space while there is a complete seal around it. This information is only for reference and we recommend you should conduct your own testing with your prototype of your end application to find the best suitable fit for your design.  

Ezurio provides layout files PADS and PADS ASCII formats. The ASCII files will import to Altium (and Protel varients) as well as Cadence (Orcad and Allegro) CAD packages. As far as we know, there is no way to import to Eagle CAD. Please be sure to use the .asc file for PCB and the .txt file for the schematic when importing to Altium. Ezurio uses ORCAD for schematics (Gerbers). 

The recommended cleanser is "hydrocarbon cleaning oil", which can be used to clean the RF shield and PCB. We do not recommend the use of alcohol as it doesn't work as well and could leave residue on the boards.  

Setting the following registry to 0 can achieve this: HKLM\Comm\SDCCF10G1\Parms\Configs\GlobalConfig DWORD: trayIcon - 0 = Hide Icon - Non-0 = Show Icon

For the 30AG, we recommend the 3.5.0.9 cab build or later for both test cases. For the 40NBT, use 3.4.13.36 cab build or later. As for the 45N, cab build from 3.5.1.6 can support both test cases.

You can modify this feature by creating a new registry called ?NotifyAttempts? under ?hklm/software/Laird/ScuTray?, this allows you to disable / enable the pop-up message for WPA / WPA2 authentication and even set the number of attempts before notification. -DWORD: NotifyAttempts -Values: 0 (disabled); NOT 0 (the number of attempts before notification)

Yes, here is an example. 1. The auto profile list contains SSID_1 and SSID_2 2. Device is connected to SSID_1 3. RSSI drops below roam trigger, the radio scans for other APs and finds SSID_2 is a better candidate 4. The radio disconnects from SSID_1 and connects to SSID_2

For the 10, 15, 30, and 40 series, the status of the LCM / SCU can be in one of two states, "non-associated? and ?associated". Once the radio has associated with an AP, it will move from "non-associated? to ?associated". If WPA / WPA2 authenticates failure, the status will switch between "non-associated? and ?associated". If authentication occurs without an IP the radio cannot be identified from the status field -- you will need to check in the IP field. For the 45 and 50 series, the status in LCM / SCU can be in one of three states, "Not Associated", "Associated", and "Connected?. Associated with no IP is a valid state for our radios to attempt to reconnect with an invalid PSK. Once the radio has associated with an AP, it will move from "not associated? to ?associated". Only after the radio authenticates and has an IP will it move to the "Connnected" state. In the case of WPA or WPA2 authenticated failure or authentication without an IP the radios will remain  in an "associated" state.

You can use the following command to make adhoc mode work: sdc_cli profile adhoc add sdc_cli profile adhoc set ssid adhoc sdc_cli profile adhoc set mode adhoc sdc_cli profile adhoc activate sdc_cli status

The radio chipset value is written by the driver when it loads, and indicates which radio is actually installed. LCM uses this value to determine some parameters that vary between radio types. If you want to hard code the Wi-Fi radio before the driver loads, you can do so with this registry: [HKEY_LOCAL_MACHINE/Comm/SDCCF10G1/Parms/Configs/GlobalConfig] "RadioChipSet"=dword:00000006 The values for that registry key are in the sdc_sdk.h as follows: typedef enum _RADIOCHIPSET { RADIOCHIPSET_NONE = 0, RADIOCHIPSET_SDC10 = 1, //BCM4318 RADIOCHIPSET_SDC15 = 2, //BCM4322, RADIOCHIPSET_SDC30 = 3, //AR6002, RADIOCHIPSET_SDC40L = 4, //BCM4319, RADIOCHIPSET_SDC40NBT = 5, //BCM4329, RADIOCHIPSET_SDC45 = 6, //AR6003, RADIOCHIPSET_SDC50 = 7, //AR6004, } RADIOCHIPSET;

Either C or C sharp can be used.

NDIS5 runs Laird's WEC7 release.

You can use this command in sdc_cli: "sdc_cli iface set hostapd wl on"

No, the patch that supports SHA-2 is in the Windows Embedded Compact 7 Monthly Update (April 2016). Prior to that, the OS itself doesn't support it.

With EAP-MS-CHAPv2, the data sent in tunnel will be encapsulated as EAP-MESSAGE AVP (attribute-value pair). In the case of MS-CHAPv2, there is no such extra encapsulation it is just the MS-CHAPv2 message.

 

WEP ON is for legacy Wi-Fi WEP with no WPA/WPA2 authentication. WEP AUTO is configured for a profile where you want to use 802.1x authentication with WEP encryption. Rather than setting WEP with a static key, WEP AUTO allows the WEP keys to be set dynamically following a successful EAP authentication.

CCKM is supported with all EAP types Laird supports?LEAP, EAP-FAST, PEAP-MSCHAPv2, PEAP-GTC, PEAP-TLS, EAP-TLS and EAP-TTLS. ACS supports all of the EAP types except EAP-TTLS. However, supporting CCKM is not dependent on using ACS as the RADIUS server. Laird can do CCKM with any RADIUS server since CCKM support is in the wireless infrastructure.

The auth type of Network EAP is an 802.11 auth type that Cisco defined that basically indicates that open 802.11 authentication and association will be followed by EAP authentication. The possible 802.11 auth types Laird support are open (0x0), shared (0x1) or Network EAP (0x80). With Cisco autonomous access points, it is possible to configure an SSID where only an 802.11 auth type of Network EAP is allowed, but this configuration is discouraged by Cisco and they indicate that if Network EAP is configured on the infrastructure, Open authentication with EAP should also be configured on that same network. Network EAP is rarely used by anyone at this point, and Cisco always recommends that it never be the only 802.11 auth type configured on the infrastructure. Either Open or Network EAP can be used with LEAP or any enterprise EAP authentication type. The only time Network EAP must be used is if that is the only 802.11 auth type that is configured on the infrastructure, but it would be rare that anyone would configure the network in that way.

The WB45 supports the following EAP types: LEAP EAP-FAST PEAP-MSCHAPv1 PEAP-MSCHAPv2 PEAP-GTC EAP-TLS EAP-TTLS PEAP-TLS

In Config page, Status page, and Diags pages, by default both BT and WiFi configuration/information are shown in LCM. Either WiFi or BT configuration/information can be removed by the editing the following registries. [HKEY_LOCAL_MACHINE\SOFTWARE\Summit\SCU] "Config"=dword:00000003 "Status"=dword:00000003 "Diags"=dword:00000003 1 = Show Wi-Fi only 2 = Show Bluetooth only 3 = Show Wi-Fi and Bluetooth.

For the WB45N, the server certificate should be located under path ?/etc/ssl?. Use a USB storage drive or wget to upload the file to WB45N and copy this file to ?/etc/ssl? folder. You will need to reboot the system to take effect. For the MSD45N, this certificate can be changed by customers during their integration. By default, it?s located in ?/etc/ssl?.

Standard: indicates PMK Caching: This means that the 802.1x authentication can be skipped on an access point that a client has already authenticated to once before. Only the 4-way handshake needs to happen. This is useful for a client that needs to reconnect to an access point that it roamed away from previously, due to signal loss etc. However, if a client has not roamed to a particular access point during its current working session, it must then authenticate to that specific access point using 802.1x. PMK Caching is the method defined in the 802.11x (WPA/WPA2) specification. Opportunistic Key Caching: With this method, a client device can skip the 802.1x authentication with an access point after a full authentication,and only needs to perform the 4 way handshake when roaming to access points that are centrally managed by the same WLC in an LWAPP or other controller-based infrastructure. This means that the client doesn't need to authenticate with access points that it wants to roam to, as long as the client has authenticated successfully to at least one of the access points in the same zone as the access point that handled the previous successful authentication. In this case, the PMK identifier has been cached at a central location, like the WLC (or wireless switch.) With OKC, the client must support this method for it to be used, even if the infrastructure has been configured with OKC enabled.

The default mode, REG_WW, will enable 802.11d. The following specific regulatory domains are supported: REG_FCC, REG_ETSI REG_TELEC REG_KCC, REG_CA, REG_FR, REG_GB, REG_AU, REG_NZ, REG_CN. The following regulatory domains are planned to be available in the near future. REG_BR (Brazil) REG_RU (Russia)

The attached document is the list current channels for the KCC domain as of 2015. In document, red means DFS required.

Current consumption for Wi-Fi radios at low power state(D3) 40NBT : 7.7 mA 45N : 200 uA note : this should be included in HIG (not only this but we should fill in all the TBD in HIG)

 

A list of our radios and supported connector types can be found here: WiFi + Bluetooth Modules

The following channels require DFS in Korea KCC/KC domain. Channel Frequency MHz 52 5260 56 5280 60 5300 64 5320 100 5500 104 5520 108 5540 112 5560 116 5580 120 5600 124 5620

 

The following three registry keys should be set to show Wi-Fi or BT interface only. [HKLM\SOFTWARE\Summit\SCU] DWORD: Status (= 3 by default) [HKLM\SOFTWARE\Summit\SCU] DWORD: Config (= 3 by default) [HKLM\SOFTWARE\Summit\SCU] DWORD: Diag (= 3 by default) value: 1 - Show Wi-Fi Only 2 - Show Bluetooth Only 3 - Show Both If you want to show Bluetooth only in LCM, you should set all the above three registry keys to 1.

 

sdcgina.exe vs sdc_gina.exe : sdcgina.exe spawns all of the components we need (e.g. supplicant, scutray). sdc_gina.exe is a UI application that, for example, pops up when the credentials must be input.

Method 1: Radio driver is asked by power manager to go to low power state Suspend/resume without cutting power to radio Method 2: Radio driver is asked by power manager to go to low power state Cut power to radio Suspend/ Resume Reapply power to radio Eject/insert radio Note 1: Method 1 is the simplest way to deal with suspend/resume, but the OEM needs to consider the current consumption of the radio at a low power state. For example, current consumption for the 40NBT is 7.7mA and for the 45N it is 200uA. Note 2 : In general, method 1 is more recommended because method 2 may cause a delay to make the radio reconnect after resume.

 

There are two reasons to send out null packets with p bit enabled. 1. Its RSSI has crossed over the Roam Trigger and the client radio is supposed to start scanning for a new AP. 2. The client radio is running one of our power-save modes (Fast or Max) and is going to sleep for a brief (e.g. 20 ms) period and is telling the AP so it will buffer traffic for it while it sleeps. After a radio has slept for some period of time (defined as the interval between DTIM periods) it is supposed to wake up and indicate to the AP that it is awake by sending a null packet with the P-bit turned off. The radio should only wake if it has traffic to send or it sees from the DTIM in the AP?s beacons that the AP has traffic to send to it.

 

For user certs, we support PKCS#12 (.pfx/.p12) or PEM (.pem). In both cases, the cert needs to contain both the user certificate and the user encryption key. For CA certs we support both the PEM (.pem) and DER (.der) format.

 

EAP-TLS is a tunnel authentication. outer identity: this is the User-Name in the RADIUS packet and visible to all intermediate parties inner identity: this is the actual user identification. It is only visible to the user himself and the Identity Provider The user cert is issued to a user identified by the username, so the username has to be configured so we know which user cert we should be using for the authentication. By default, the username is also used during authentication as the outer identity which gets sent in the identity response packet.

 

mandatory/optional input for EAP type   EAP credentials Mandatory input Optional input LEAP User name, user password   EAP FAST User name, user password PAC file, FAC password PEAP MSCHAP User name, user password CA cert PEAP GTC User name, user password CA cert EAP TLS User name, user cert CA cert EAP TTLS User name, user password CA cert PEAP TLS User name, user cert CA cert   Note 1: this settings should be read in user perspective but not for actual implementation. For example, when a user does not input PAC file, it will use auto PAC provisioning. If a user inputs it, it will do a manual PAC provisioning. Note 2: user password is not used for TLS but only user cert is used instead.
