==DWM DWS ==DWM DWS is a Dave Wireless Module, more detail details at the [[Wireless Module (DWM)DWS_ADD-ON|DWM DWS page]].
=== Description ===
The DWM 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 DWM DWS (''optional'') add-on module.
The module is built around an LS Research TiWia Telit WE866C6-BLE Integrated Transceiver Modules for WLAN P Dual Band (2.4GHz and 5GHz) 802.11 b/g/n ac WiFi and Bluetooth5 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 mapping ===
The BT peripheral is mapped to <code>/dev/ttyxxxttySTM3</code> device in Linux.
The control signals are managed by <code>rfkill</code> in Linux.
=== Device usage ===
The WiFi peripheral use uses the standard kernel interface and network protocol stack.
The BT peripheral use uses the standard kernel <code>hci </code> interface.
