Trying to use NRF24L01+ on ESP8266, using the ESP8266 as MCU (i.e. not an Arduino or ATmega328). See https://github.com/esp8266/Arduino for details on initial setup of ESP8266 as Arduino-compatible MCU. The serial output below does not show expected messages: a) the full output shows up all at once then stops dead and b) the values for _salt, vo…

	/*
	system_rtc_mem_write
	Function:
	During deep sleep, only RTC still working, so maybe we need to save some user data in RTC memory.
	Only user data area can be used by user.
	\|<--------system data--------->\|<-----------------user data--------------->\|
	\| 256 bytes \| 512 bytes \|

	Note:
	RTC memory is 4 bytes aligned for read and write operations. Parameter des_addr means block number(4 bytes per block).
