CC2640通过OAD把协议栈4.2升级5.1疑问

Other Parts Discussed in Thread: CC2640, BLE-STACK, CC2650

公司已有产品使用芯片 CC2640

协议栈是2_01_01_44627.应用程序相关库函数等用法也是基于此协议栈。

看2020年3月CC2640支持蓝牙5.1(https://www.ti.com.cn/tool/cn/BLE-STACK)。

那请问:现在可否通过OAD,只升级协议栈部分,升级到蓝牙5.1(BLE-STACK v2.2.4 )?


若是可以,只升级协议栈,那应用代码无需修改吧?

若是可以,那硬件不需要改动啥吧?
