I like ESP8266 and ESP8285 and ESP32

- Sat Feb 21, 2015 9:26 am #10334 Well, I played with this a bit.

I only have an 01 module to test with, so I can only try one pin (4=GPIO2) at the moment. No success I'm afraid.

Example:

Code: Select allgpio.mode(4, gpio.INPUT, gpio.PULLUP)
node.enablewakeup(4, "both")
node.dsleep(2000)


Pulled the pin low but no luck in waking up. If somebody with more pins wants to try on a few others and report their results, I'd be interested.

Here is the diff for node.c that adds the enablewakeup command to lua.

- Sat Feb 21, 2015 9:55 am #10336 Can you please try it with gpio 2 ,
interrupt high
gpio2 connected to RST
deepsleep time = 0 ?
