什么是可升级的字段？

嗨，大家能通过UART来解释什么是可升级的字段吗？我只限于ISSC蓝牙闪存工具和使用GUI更新模块吗？是否有任何ISSC闪存工具是命令行驱动来自动化固件升级过程？我认为它也没有OTA选项的模块，如RN4020？谢谢

    Hi all,

Can someone explain what field upgradable via UART actually means?

Am I limited only to the ISSC Bluetooth Flash Tool and updating the module using the GUI?

Are there not any ISSC flash tools that are command line driven to automate the firmware upgrade process?

I take it also there is no OTA option for the module like the RN4020?

Thanks
