The module is built around an LS Research TiWi-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 HCI transport layer. Both WLAN and Bluetooth share the same antenna port.

===Calibration process===
 
−
The radio interface of the DWM module is configured by several parameters. These parameters are set through a calibration process, that is described in detail [http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Calibration_Process here].
 
−
 
 
−
The calibration process—that produces an NVS file—is not trivial. Apart from the chip itself (Texas Instruments WL1271L in this case), it depends on:
 
−
*the antenna - a list of [https://www.lairdconnect.com/wireless-modules/wifi-modules-bluetooth/tiwi-ble#certified-antennas certified antennas] and cables can be found in the TiWi Module device datasheet. Use of these antennas does not require additional FCC/IC/ETSI certifications.
 
−
*the firmware version downloaded to the chip: please refer to the proper firmware available on your Linux distribution for matching the kernel driver and run properly the calibration process
 
−
*the initialization data, typically stored in an INI file: please refer to the [https://www.lairdconnect.com/wireless-modules/wifi-modules-bluetooth/tiwi-ble#documentation Laird Connectivity TiWi documentation] for checking the proper INI file configuration
 
−
*the Calibrator source code [https://github.com/TI-OpenLink/ti-utils/tree/ol_R5.SP8.01 here]
 
−
More information about kernel driver and calibration on the [https://www.lairdconnect.com/forum/tiwi-ble/online-documentation/support-and-tools Laird Support and Tools] web page.
 
−
 
 
−
==== MAC address ====
 
−
The MAC address is set at calibration time for WLAN. To use the built in MAC address for WLAN be sure to pass a MAC address of <code>00:00:00:00:00:00</code> as a parameter to the auto-calibrate function. To set a custom MAC address for WLAN just pass the desired value into the auto-calibrate function.
 
−
 
 
−
==== NVS ready-to-use calibration files ====
 
−
The following links refer to specific use cases, where the resulting NVS file is provided along with DAVE Embedded Systems products integrating DWM module.
