chaeplin / ESP8266 Code (RX node)
Created December 18, 2015 00:27 — forked from crcastle/ESP8266 Code (RX node)
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…

*** Sample using esp-01, D16 is connected to RST
*** If DHT22 is powered by a gpio( VCC of DHT22 is connected to a gpio) and OUTPUT of DHT22 is connected to D2, boot will fail.
*** Power off ----> D2 is in LOW( == DHT22 is in LOW) ==> SDIO boot mode.
Temperature and humidity values are each read out the results of the last measurement.
For real-time data that need continuous read twice, we recommend repeatedly to read sensors,
and each read sensor interval is greater than 2 seconds to obtain accuratethe data.
