The WFM280 is a highly integrated Combo Module IEEE 802.11 b/g/n Wireless LAN
(WEAN), Bluetooth 2.1/3.0/4.0 and FM receiver. It combines a WLAN MAC, a 1T1R
capable WEAN baseband, BT Protocol Stack (LM, LL, and LE), BT Baseband, modem,
and WLAN/BT RF in a single Module. The WFM280 provides a complete solution for a
high performance integrated wireless LAN, Bluetooth device.
The WFM280 Bluetooth controller complies with Bluetooth core specification v4.0,
and supports dual mode (BR/EDR + AMP + Low Energy Controllers). It is compatible
with previous versions, including v2.1 + EDR and v3.0 + HS. For BR/EDR, it supports
scatternet topology and allows four active links in slave mode, and seven active links
in master mode. For Low Energy, it supports multiple states and allows eight active links
in master mode. The links in BR/EDR and LE can be active simultaneously.
