gpio_pin_wakeup_enable(uint32 i, GPIO_INT_TYPE intr_state);
Posted: Sat Feb 21, 2015 5:34 amAnyone has any success with it ? That comes with the 0.9.5 and lets you to wake the module via pin interrupt.

Re: gpio_pin_wakeup_enable(uint32 i, GPIO_INT_TYPE intr_stat
Posted: Sat Feb 21, 2015 9:26 amWell, 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:
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.

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

Posted: Sat Feb 21, 2015 9:55 amCan you please try it with gpio 2 ,
interrupt high
gpio2 connected to RST
deepsleep time = 0 ?
