高通modem代码架构 高通modem配置

一.SIM卡开机延时：

NV4205, 数组[57]对应值：以s为单位，可以抓到卡开机log；

二.modem oprt_mode配制

70310 0 => UI Task Exit; 1 => UI Task configures for autoanswer,

mode online： /nv/item_files/Thin_UI/enable_thin_ui_cfg ThinUI

三.LTE cat配制：

modem_proc/lte/api/lte.h

配制方法：EFS file name:lte_category

Location of EFS file:/nv/item_files/modem/lte/common/

Category value：

0x01 for cat-1

0x02 for cat-2

0x03 for cat-3"

以及代码：

/*! @brief UE Category

*/

#ifdef FEATURE_LTE_IOE

  #define LTE_UE_CATEGORY                                      1  

#else

  #define LTE_UE_CATEGORY                                      4

#endif

四.当有另一路PDN发起连接时，检查已有PDN是否有业务，若没有业务则依据如下配制决定是否断开已有连接：/nv/item_files/modem/data/3gpp/ps/remove_unused_pdn

五. 通过QXDM OTA log 查看设备支持的各制式频段:

六.电信4G ONLY卡兼容：

电信 4G ONLY卡（删除了CSIM/CDMA APP)：

sdss.c  10820] =SD=  chen: sdss_get_operator_name ( SYS_MODEM_AS_ID_1 ) =1,2,3//MMGSDI_APP_USIM

sdss.c  10821] =SD=  chen: orig_mode =0,1,1

sdss.c  10822] =SD=  chen: hybr_pref =4,1

普通电信卡：

sdss.c  10820] =SD=  chen: sdss_get_operator_name ( SYS_MODEM_AS_ID_1 ) =1,3//SDSS_SUBSC_1X_GW,3

sdss.c  10821] =SD=   orig_mode =0,0//PRL,1

sdss.c  10822] =SD=   hybr_pref =4,1

联通卡：

sdss.c  10820] =SD=  sdss_get_operator_name ( SYS_MODEM_AS_ID_1 ) =0,2,3

sdss.c  10821] =SD=   orig_mode =0,1,1

sdss.c  10822] =SD=   hybr_pref =1,0//sdss_is_1x_sxlte() FALSE

移动卡：

sdss.c  10821] =SD=   orig_mode =0,1,1
