<section end="History" /><section begin="Body" /> ==DWM ==DWM is a Dave Wireless Module, more detail at the [[Wireless Module (DWM)|DWM page]]. === Description ===The DWM 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 interface ==(''optional'') add-on module.
''TBD: sostituire le sezioni con le informazioni sull'uso della periferica e del suo connettore''''Nell'esempio di seguito c'è la descrizione dell'interfaccia UARTThe module is built around an LS Research TiWi-BLE Integrated Transceiver Modules for WLAN 802.11 b/console''g/n and Bluetooth.
=== Description ===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.
The DWM interface available on the Evaluation Kit at the connector ''TBD:Jxxx''.
''Jxx'' is a ''TBD[[File:ETRA-EVK-DWM-connector.png|thumb|left|300px|DWM connector]] [[File:ETRA-EVK-DWS-type'' header connector for the RS232 twowifi-wires UART3 port, used for debug purposes (bootloader and operating system serial console)module.png|thumb|center|300px|DWM wifi module mounted on board]]

=== Device mapping ===
UART3 {| style="color:#000000; border:solid 2px #73B2C7; background-color:#ededed;font-size:95%; vertical-align:middle;"| [[File:TBD.png|30px]]| '''Section not completed yet'''|} The WiFi peripheral is mapped to the corresponding <code>wlan<X></code> device in Linux. The network peripheral is visible under the <code>ifconfig</code> network configuration utility. The BT peripheral is mapped to <code>/dev/ttymxc2ttyxxx</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernelcontrol signals are managed by <code>rfkill</code> in Linux.
=== Device usage ===
To connect to The WiFi peripheral use the debug serial port:standard kernel interface and network protocol stack.
# connect The BT peripheral use the DB9 adapter bracket to the J22 connector on the SBCX board# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1standard kernel hci interface.
