域格模块调试

1.id添加

2.有时候网卡usb0会注册成eth1，优化方式如下：

                    ((dev->driver_info->flags & FLAG_POINTTOPOINT) == 0 ||

                /* WLAN devices should always be named "wlan%d" */
                if ((dev->driver_info->flags & FLAG_WLAN) != 0)

3.替换域格提供的库：

　　diff --git a/4g_modem/lib64/librk-ril.so b/4g_modem/lib64/librk-ril.so

 

4.模组厂建议用RNDIS

 用rndis，需要设置属性：

persist.ril.data.prefer=rndis

 

5.完成以上步骤，可以有图标出来，但没有信号

 需要设置属性

persist.ril.sig.poll=true

 如果支持sim卡座需要支持热插拔的功能，还需要更新so库和属性

PRODUCT_PROPERTY_OVERRIDES += persist.ril.hotplug=2

 

支持模块休眠功能：

PRODUCT_PROPERTY_OVERRIDES += persist.ril.csclk=1

出海外系统apn可能失效，这个用于修复：

PRODUCT_PROPERTY_OVERRIDES += persist.ril.ena.initapn=1
