#### 介绍
ICOE 功能移植SDK基于 android hidl2.0 

#### 软件架构
软件架构说明


#### 移值说明

基于MTK android12的移植 例子

1.关闭系统的GNSS功能

	device/mediatek/vendor/xxxxxx/VendorConfig.mk
	device/mediateksample/xxxxxxx/ProjectConfig.mk

	kernel-4.19/arch/arm64/configs/xxxxxx_64_debug_defconfig
	kernel-4.19/arch/arm64/configs/xxxxxx_64_defconfig

	MTK_AGPS_APP=no
	MTK_GPS_SUPPORT=no
	MTK_LOG_SUPPORT_GPS=no


2.添加源码

	vendor/mediatek/proprietary/hardware/bdicc
	 gnss_hidl2.0
	 vproduct


3.增加ICOE模块编译

	device/mediatek/vendor/common/device.mk
	PRODUCT_PACKAGES += android.hardware.gnss@2.0-service-bdicc
	PRODUCT_PACKAGES += bdicc-vproduct

	PRODUCT_COPY_FILES += vendor/mediatek/proprietary/hardware/bdicc/MSLConfig.txt:vendor/icoe/MSLConfig.txt
	PRODUCT_COPY_FILES += vendor/mediatek/proprietary/hardware/bdicc/MSLConfig.txt:$(TARGET_COPY_OUT_VENDOR)/etc/MSLConfig.txt


4.增加selinux权限 

	system/sepolicy/vendor/file_contexts b/android12/system/sepolicy/vendor/file_contexts
	
	/(vendor|system/vendor)/bin/hw/android\.hardware\.gnss@2\.0-service-bdicc           u:object_r:hal_gnss_default_exec:s0
	/(vendor|system/vendor)/bin/hw/android\.hardware\.sensors@2\.0-service-bdicc        u:object_r:hal_gnss_default_exec:s0
	/(vendor|system/vendor)/bin/hw/android\.hardware\.bdxtvchannel@1\.0-service-bdicc   u:object_r:hal_gnss_default_exec:s0


	system/sepolicy/vendor/hal_gnss_default.te
	
	allow hal_gnss_default self:capability2 { block_suspend };
	#allow hal_gnss_default self:capability { dac_override };

	allow hal_gnss_default radio_device:chr_file { getattr ioctl open read write };
	allow hal_gnss_default tty_device:chr_file { ioctl open read write };
	allow hal_gnss_default sysfs_wake_lock:file { open read write };
	allow hal_gnss_default vndbinder_device:chr_file { ioctl open read write map };

	allow hal_gnss_default vendor_data_file:dir { add_name remove_name write };
	allow hal_gnss_default vendor_data_file:fifo_file {write getattr open read setattr relabelfrom };
	allow hal_gnss_default vendor_data_file:sock_file { create unlink };

	allow hal_gnss_default property_socket:sock_file { write };
	allow hal_gnss_default init:unix_stream_socket { connectto };


5.增加starcourse APP

	device/mediatek/system/common/device.mk

	PRODUCT_PACKAGES += starcourse
	PRODUCT_PACKAGES += UtilSystemProperty

6.增加starcourse 源码到相应目录

	vendor/mediatek/proprietary/packages/apps

#### 使用说明

1.修改TTY和电源节点，gnss_hidl2.0/android.hardware.gnss@2.0-service-bdicc.rc

    setprop persist.vendor.bdicc.dev_name /dev/ttyUSB1               ---> 修改为相应的串口TTY节点
    setprop persist.vendor.bdicc.gnss_ctldev_devname /dev/ttyUSB0    ---> 修改电源控制节点（'1':on,'0'：off）

2.提供节点权限

    chmod 0777 /dev/ttyUSB0     -->串口TTY节点
    chmod 0777 /dev/ttyUSB1     -->电源控制节点 


3.升级触发，通过local socket 发送 "upgrade" 到 server 节点
  
    #define server "/data/vendor/bdicc/socket/server"

    int icoe_localsocket_connect(void)
    {
        int ret = -1;
        int sock ;
        struct sockaddr_un addr;
        socklen_t socket_len;
        memset(&addr, 0, sizeof(addr));
        size_t namelen;
    	
        sock = socket(AF_LOCAL, SOCK_STREAM, 0);
        if(sock < 0) {
            printf("socket create error: %s", strerror(errno));
            return -1;
        }
    	
        namelen = strlen(server);
        /* unix_path_max appears to be missing on linux */
        if (namelen >
            sizeof(addr) - offsetof(struct sockaddr_un, sun_path) - 1) {
            printf("socket address error: %s", strerror(errno));
            return -1;
        }
    
        strcpy(addr.sun_path, server);
    
        addr.sun_family = AF_LOCAL;
        socket_len = namelen + offsetof(struct sockaddr_un, sun_path) + 1;
        
        ret = connect(sock, (struct sockaddr*)&addr, socket_len);
        if(ret < 0) {
            printf("connect server failed %s \n", strerror(errno));
            return ret;
        }
    	
        return sock;
    }
    
    
    int icoe_localsocket_send(int socket,char *cmd,int len)
    {
        return send(socket, cmd, len, 0);
    }


    int main(void)
    {
    	int sock ;
    	int ret,t = 0;
    	char cmd[] = "upgrade";
    	
    	int len = 0;
        struct timeval testTime1, testTime2;
        double db_time1, db_time2;
        double max_wait_time = 0.0;
    	char rcvBuf[1024];
    	
    	do{
    		sock = icoe_localsocket_connect();
    		
    		if(sock < 0 ){
    			printf("Error:icoe localsokcet create error %d\r\n",sock);
    		}
    		
    		ret = icoe_localsocket_send(sock,cmd,strlen(cmd));
    		if(ret < 0 ){
    			printf("Error:icoe localsocket send \r\n",ret);
    		}
    		
    		t++;
    		if(t > 3){
    			return -1;
    		}
    	}while(ret < 0);
    	
    	max_wait_time = (double)90*1000;
    	gettimeofday(&testTime1, NULL);
    	db_time1 = testTime1.tv_sec * 1000 + (double)(testTime1.tv_usec) / 1000;
    
    	while(max_wait_time > 1e-1) {
    		memset(rcvBuf, 0, sizeof(rcvBuf));
    		if(recv(sock, rcvBuf, sizeof(rcvBuf) - 1, MSG_DONTWAIT) > 0 ) {
    			printf("recv %s\n", rcvBuf);
    			if(strstr(rcvBuf, "succ")) {
    				printf(" update success\n");
    				close(sock);
    				return 0;
    			}else if (strstr(rcvBuf, "fail")) {
    					printf("fail to update\n");
    					close(sock);
    					return -1;
    			}
    		}
    
    		gettimeofday(&testTime2, NULL);
    		db_time2 = testTime2.tv_sec * 1000 + (double)(testTime2.tv_usec) / 1000;    
    		max_wait_time -= db_time2 - db_time1;
    		db_time1 = db_time2;
    	}
    
    	if(max_wait_time <= 1e-1) { 
    	   printf("fail to recv response from server\n");
    	   close(sock);
    	   return -1;
    	}
        
        return 0;
    	
    }
