BH 在Android下升级N725-CA模块的升级流程：
1、确保模块处于正常开机状态，判断方法：发送lsusb 返回PID:VID：2949:7252
2、确保模块正常枚举ttyACM0端口，可通过ls /dev/ttyACM查看
3、往/dev/ttyACM0口发送进入下载模式指令AT M Y D O W N L O A D = 1 让模式进入下载模式，使用 e c h o 方式发送是： e c h o − e ′ A T MYDOWNLOAD=1让模式进入下载模式，使用echo方式发送是：echo -e 'AT MYDOWNLOAD=1让模式进入下载模式，使用echo方式发送是：echo−e′ATMYDOWNLOAD=1\r\n' > /dev/ttyACM0 ，也可以使用串口工具发送。
4、检查模块是否成功进入下载模式，可使用lsusb指令查询，返回PID VID:2ecc 3001 表示模块正常进入下载模式。如果没有进入下载模式，需要返回第三步重新尝试。
5、运行fbfdownloader_cross升级工具进行升级，指令格式为：./fbfdownloader_cross -b BinFile.bin，升级过程中不能断电，等待升级完成，一般为30-40S，完成后会打印Burn Successfully 等关键字。
6、升级完成后模块会自动重启，lsusb查询返回PID:VID：2949:7252 ， ls /dev/ttyACM 返回ttyACM0端口。
7、发送AT+CGMR指令查询模块软件版本，使用echo方式命令为：echo -e "AT+CGMR\r\n" > /dev/ttyACM0 ，需要正常查询到软件版本，如果一次没有返回，需要重试。
8、给模块发送echo -e "ATPROD=0\r\n" > /dev/ttyACM0 指令让模块退出产线模式。需要返回OK，没有返回需要重试。
9、重启模块，因为ATPROD=0命令 重启生效。
1、BH Android下面发N725进入升级的指令格式：
echo -e 'AT$MYDOWNLOAD=1\r\n' > /dev/ttyACM0 （客户目前使用这个）
echo -e "AT$MYDOWNLOAD=1\r\n" > /dev/ttyACM0
2、BH 客户Android下运行./fbfdownloader_cross升级工具打印如下：
