<section end="History" /><section begin="Body" /> ==DWM interface ==
''TBD: sostituire le sezioni con le informazioni sull'uso della periferica e del suo connettore''==DWM ==''Nell'esempio di seguito c'è la descrizione dell'interfaccia UART/console''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.''
The J8 is a 30-pins 0.50mm Pitch SlimStack™ Receptacle. This connector is dedicated to the DWM interface available on the Evaluation Kit at the connector ''TBD:Jxxxoptional''add-on module.
''Jxx'' The module is a ''TBD:connectorbuilt around an LS Research TiWi-type'' header connector 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 RS232 two-wires UART3 HCI transport layer. Both WLAN and Bluetooth share the same antenna port, used for debug purposes (bootloader and operating system serial console).
The following table describes the interface signals:

=== Device mapping ===
UART3 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.
