- Wed Feb 11, 2015 4:56 am #9446 Using this code,

node.dsleep(3600000000)

makes my esp8266 wake up too early, 35 minutes instead of an hour.

I’m guessing this might have something to do with timer overflow as discussed at

viewtopic.php?t=624&p=4217

Is there a workaround?

LUA works with signed 32 bit numbers from -2,147,483,648 to 2,147,483,647.
2,147,483,647 (the biggest positive number) results in ~ 35.79 minutes.

Workaround: 2 x 1,800,000,0000?

node.dsleep(2*1800000000)

still only 35 minutes sleep.....

Code: Select allnode.dsleep(1800000000)


one after another? But that will `unsleep` the device anyway.
