Introduction[edit | edit source]
The module is built around an LS Research TiWi-BLE Integrated Transceiver Modules for WLAN 802.11 b/g/n and Bluetooth. The module implements 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.
Features[edit | edit source]
- Based on Texas Instruments WL1271L Transceiver
- IEEE 802.11 b,g,n,d,e,i, compliant
- Bluetooth 2.1+EDR, Power Class 1.5
- Full support for BT4.0 BLE and ANT
- Reduced footprint: 25 mm x 38 mm
- Low height profile
- U.FL connector for external antenna
- Integrated band-pass filter
- Industrial operating temperature range: -40 / +85 °C
Interface timings[edit | edit source]
