DWSEdit
DWS is a Dave Wireless Module, more details at the DWS page.
DescriptionEdit
The DWS interface is available on the Evaluation Kit at the connector J8.
J8 is a 30-pins 0.50mm Pitch SlimStack™ Receptacle. This connector is dedicated to the DWS (optional) add-on module.
The module is built around a Telit WE866C6-P Dual Band (2.4GHz and 5GHz) 802.11 ac WiFi and Bluetooth 5 module.
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.

Device mappingEdit
The WiFi peripheral is mapped to the corresponding wlan0 device in Linux. The network peripheral is visible under the ifconfig network configuration utility.
The BT peripheral is mapped to /dev/ttySTM3 device in Linux.
The control signals are managed by rfkill in Linux.
Device usageEdit
The WiFi peripheral uses the standard kernel interface and network protocol stack.
The BT peripheral uses the standard kernel hci interface.
