DESCRIPTION
The TiWi-R2 module is a high performance 2.4 GHz
IEEE 802.11 b/g/n and Bluetooth 2.1+EDR radio in a
cost effective, pre-certified footprint.
The module realizes the necessary PHY/MAC layers
to support WLAN applications in conjunction with a
host processor over a SDIO interface.
The module also provides a Bluetooth platform
through the HCI transport layer. Both WLAN and
Bluetooth share the same antenna port.
Need to get to market quickly? Not an expert in
802.11 or Bluetooth? Need a custom antenna?
Would you like to own the design? Would you like
a custom design? Not quite sure what you need?
Do you need help with your host board? LSR Design
Services will be happy to develop custom hardware
or software, integrate the design, or license the
design so you can manufacture yourself. Contact us
at [email protected] or call us at 262-375-4400.

INI FILE RADIO PARAMETERS AND BLUETOOTH PATCH FILES
There are ini files that contains WLAN radio parameters which are critical to both the RF performance and EMC
compliance of the module in various antenna configurations.
The ini files available on the LSR wiki website are only intended to be used with the LSR WLAN Eval Tool. Note
that the ini file will not work when using the TiWi-R2 module in normal operation which typically involves an
operating system. To use the TiWi-R2 module in normal operation, refer to specifics contained in the TiWi
Family INI File Radio Parameter User Guide which is also available for download on the LSR wiki website,
http://wiki.lsr.com/ .
The settings specified in the appropriate ini file must be used to operate the module in compliance with the
modular certification for FCC or ETSI. There are two ini files for operating the module in compliance with FCC
regulations that corresponds to different antenna configuration, and a different ini file for operating the module
in compliance with the ETSI regulations.
The Bluetooth patch files are available on the LSR wiki website. The appropriate patch file must be selected to
operate the module in compliance with the modular certification for FCC or ETSI.
