Android 8 4G调试

  1. 参考其他文档驱动配置。  确保插入  /dev/ttyUSB* 节点出现。

通过AT 指令查看设备

通过AT指令打电话

echo -e "ATD110;\r\n" >/dev/ttyUSB2

echo -e "ATD10086;\r\n" >/dev/ttyUSB2

echo -e "ATD15112673367;\r\n" >/dev/ttyUSB2

 

查看模块型号

echo -e "AT+CGMM\r\n" >/dev/ttyUSB2

 

获得GSM模块的IMEI(国际移动设备标识)序列

echo -e "AT+CGSN\r\n" >/dev/ttyUSB2

 

这命令用来读取或者识别SIM卡的IMSI(国际移动签署者标识)

echo -e " AT+CCID \r\n" >/dev/ttyUSB2

 

 

 

AT+CCID

 

 

+CCID: 89860000191807884521

 

AT指令:

echo -e "AT+CSMINS?\r\n" >/dev/ttyUSB2

echo -e "AT+COPS\r\n" >/dev/ttyUSB2

\r\n" >/dev/ttyUSB2

echo -e "AT+CSMINS\r\n" >/dev/ttyUSB2

echo -e "AT+COPS=?\r\n" >/dev/ttyUSB2

 

 

 

 

 

二 RIL 层代码移植。

  1. 从代理商可以ril层库文件及ppp拨号可执行文件。

# ls  libquectel-ril/armeabi

chat  ip-down  ip-up  libreference-ril.so

 

修改mk文件将上面拷贝对应目录。

 

PRODUCT_COPY_FILES += \

    device/softwinner/venus-a3/ec20/ip-up:system/etc/ppp/ip-up \

    device/softwinner/venus-a3/ec20/ip-down:system/etc/ppp/ip-down \

    device/softwinner/venus-a3/ec20/chat:system/bin/chat \

    device/softwinner/venus-a3/ec20/libreference-ril.so:$(TARGET_COPY_OUT_VENDOR)/lib/libreference-ril.so \

 

 

  1. 配置init.rc。 android8 init.rc再对应模块里面rc配置就好。 由于我们系统默认selinux开启得,这里按照文档提示 服务ril-daemon用户是 radio

service ril-daemon /vendor/bin/hw/rild -l /vendor/lib/libreference-ril.so

    class main

    user radio

    group radio cache inet misc audio sdcard_rw log

    capabilities BLOCK_SUSPEND NET_ADMIN NET_RAW

 

 

3.Android8及以上版本Framework通过HIDL和ril daemon服务通信。

 配置HIDL文件

android/device/softwinner/venus-a3/configs/ manifest.xml

 

 

  

   

        android.hardware.broadcastradio

        hwbinder

        1.0

       

            IBroadcastRadioFactory

            default

       

   

   

        android.hardware.radio.deprecated

        hwbinder

        1.0

       

            IOemHook

            slot1

       

   

   

        android.hardware.radio

        hwbinder

        1.0

       

            IRadio

            slot1

       

   

 

 

5.

 

/dev/ttyUSB0 0660 radio radio

/dev/ttyUSB1 0660 radio radio

/dev/ttyUSB2 0660 radio radio

/dev/ttyUSB3 0660 radio radio

 

 

 

/dev/cdc-wdm* 0660 radio radio

/dev/qcqmi* 0660 radio radio

/dev/cdc-acm* 0660 radio radio

 

6.

最后发现开机时候 4G网络不通,插拔一下就可以上网, 发现是selinux的原因

可以修改system/core/init/init.cpp   is_enforcing值赋值为false

          is_enforcing = false;

            if (security_setenforce(is_enforcing)) {

                PLOG(ERROR) << "security_setenforce(%s) failed" << (is_enforcing ? "true" : "false");

                security_failure();

            }

 

 

logcat –b radio & //ril log
logcat –s pppd & //ppp 拨号 log
logcat –c –b radio & //清除以前 raido log
