using OTA messages.<\/li>\n<li>Mobile management profile in the RDK-B, there is a number of options from the cellular modem that must be exposed in the DM.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><u>In order to allow proper consistency in the design for different platforms, we have decided to work using standard kernel drivers, starting the analysis for QMI.<\/u><\/p>\n<p>QMI is easily accessible in recent enough Linux kernels (&gt;= 3.4) through the <strong>cdc-wdm<\/strong> and <strong>qmi_wwan<\/strong> drivers.<\/p>\n<p>Once these drivers are in place and the modem gets powered on and recognized, the kernel will expose a new <code>\/dev\/cdc-wdm<\/code> device that can talk QMI with the CPE,<\/p>\n<p>along with a <code>wwan<\/code> interface associated with each QMI port to transmit and receive traffic through a PDN connection.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n<div class=\"columnLayout single\" data-layout=\"single\">\n<div class=\"cell normal\"
