In IOT SDK, perhaps there are some methods that allow user to update the needed key from an apps(for example esp8266 android related apps).the apps will request the key from server separately, later when the apps already got the key, we can easily write this key to that specific address of the esp device.

It would be very nice to have some sort of "threshold" for generating the SPI (or other UART...) interrupts.
Interrupts are now triggered only on completion of some action - for example int on end transfer.
What I mean is to have some way of configuring the interrupt to trigger before the entire fifo/buffer is processed.
Why? If you need to have a "constant" output stream (on SPI or UART) you should start filling (or reading) the fifo before the end of transmission/reception otherwise there will always be gaps - after the interrupt triggers you need time to re-fill the fifo and start a new transfer.
