libertas libertas_spi When the driver detects the WLAN chip, first the firmware must be uploaded. The current version of firmware is fw 9.70.3p37. The corresponding files (spi8686.bin and spi8686_helper.bin) must be situated in the filesystem in /lib/firmware/libertas. When set up, linux will bring up an eth-device. Now the standard-linux items can be used for communications. 4.2 Linux driver Bluetooth The Bluetooth-Chip of the AGO WLAN / Bluetooth Module, Bluemod B20, ist controlled by the following linux-drivers:
- standard USB driver
- NXP-ISP1760 driver (USB hub)
- Generic Bluetooth USB driver ver 0.4 The device is enumerated by the standard- and ISP1760-USB drivers. All following accesses to this chip are done with standard-linux-tools for USB (e.g. hcitool) via the Generic Bluetooth USB driver ver 0.4. 5 Housing Guidelines The individual case must be checked to decide whether a specific housing is suitable for the use of the dedicated antenna. A plastic housing must at least fulfill the following requirements:
Non-conductive material, non-RF-blocking plastics No metallic coating ABS is suggested Date Autor MGOE 21.01.2011 Filename Page 8 / 10 Power supply UM0358_WLAN_BTH 6 The module requires a power supply with following characteristics:
3,3V 0,1V low noise (10mV) Due to the technological requirements and the pulsed radio transmission the supply needs to be fed by an ultra fast (response time 20s) linear regulator. NOTE: You must ensure that during operation the supply voltage never drops below 3.0 V. Otherwise the flash contents (firmware and/or configuration data) can get lost. 6 Attachment Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1 through 11. Date Autor MGOE 21.01.2011 Filename Page 9 / 10 UM0358_WLAN_BTH This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna (except Bluetooth module B2029 FCC ID: YM6-B2029), 3) For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labelled in a visible area with the following:
- Contains TX FCC ID: YM6-AWGH321 and FCC ID: YM6-B2029 or
- Contains TX FCC ID: YM6-AWGH321 Contains TX FCC ID: YM6-B2029 Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. Filename Date Autor MGOE 21.01.2011 Page 10 /
