Description

The TiWi-R2 is Not Recommended for New Designs (NRND).  The TiWi-BLE is the footprint and electrically compatible module that should be used in place of the TiWi-R2.  The TiWi-BLE adds Bluetooth Low Energy (BLE) functionality in addition to WiFi and Bluetooth.  You can access the TiWi-BLE module here.

The TiWi-R2 Bluetooth and WiFi module is a high performance 2.4 GHz IEEE 802.11 b/g/n 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.
