Configuring Non-Volatile-Item  The latest LS-Images (v6023 and onwards) supports NV-Item from application only and is accessible from Application Shell prompt. NV-item in U-Boot is not supported anymore.  To configure all the NV-Item values at one shot as per customer choice, customers can use the envitem.xml file. This xml file is used to generate a final Golden-Image for production. Non-Volatile (NV) item in LibreSync can be configured through command line or by editing the env-item.xml file, shared by Libre. To configure the NV-Item, type the below command in the command line and Reboot the LS-Module to apply the changes. Command Syntax #setenv <NV_item_name> <<value>> #reboot There should be space between setenv and <NV_item_name> and between the <NV_item_name> and <<value>> . To know the value of the NV-Item set, type the below command in the command line. Command Syntax #getenv <NV_item_name> To reset all the NV-Items to factory default values, type the below command in the command line. Command Syntax #SetFacDefault
LS6 User Guide Libre Wireless Technologies User Guide: LS6, Ver. 6.0 Page 27 of 81 Libre Confidential To know all the NV-items values, type the below command in the command line.

Libre APP for Android LUCI enables user to remotely, control the LibreSync LS6 enabled product using the Libre Application for android. The application can be used to browse DLNA-DMS in the network, SD Card connected to device and other online radio stations such as vTuner and TuneIn , and stream music using the DMP feature supported by LS6. For more information on using Libre APP refer LibreWireless-Usability_Guide_Dynamic_Direct_Multi-Node_Streaming 7.2. DDMS A Wireless Dynamic Direct Multi-Node Streaming (DDMS) Zone is a group of nodes, (DDMS enabled speakers) chosen dynamically by an end user to synchronously play audio from a given content source. This group of speakers can play music from any Audio Source synchronously without any delay between the nodes. Each group can consists of two or more nodes. DDMS Group is created in two mode  Home-Network Mode – A state in which DDMS-Nodes creates a Sound-Scene, by connecting to the Access-Point (AP) in the Home-Network. The Audio Source (smartphone) streaming the audio should be connected to the same AP.  Stand-Alone Mode - A state in which DDMS-Nodes creates a Sound-Scene, by connecting to the Master using the SSID of Sound-Scene in SA-Mode. In this state there is no Access-Point (AP) or home infrastructure present. The Audio Source (smartphone) streaming the audio should be connected to the same SSID of the Sound-Scene in SA-Mode.

Multiple SSID LibreSync allows LS-Enabled devices to store Eight different network’s information in Home Network mode. If the device lose network, it would scan for earlier connected networks and then connects to the network with highest signal strength. The details of each network’s SSID and Passphrase are stored in HN_SSID_x and HN_PASSPHRASE_x respectively. The device starts storing the information from HN_SSID_7 till HN_SSID_0 and then erases the oldest i.e., HN_SSID_7 to write the new network details. 7.21. Zone Volume. Zone Volume uses scaling ratios to provide a good user experience and intuitive system response based on controlling volume levels for dynamic groups of speakers - called "Sound Scenes”. Zone volume manages an overall Sound Scene’s Volume. Once speakers are adjusted, the Sound Scene Volume will raise and lower each speaker’s volume in a relative way keeping the relationship of volume level between speakers. However as you lower the Sound Scene’s Volume level to zero, every speaker in the Scene will converge to zero at the same time. For more details see LUCI Tech Note. 7.22.
