net.createConnection() crashes ESP8266
Posted: Mon May 11, 2015 3:59 amHi,
I am new to using these boards this weekend. I coded up the below which works when in small separate parts, but fails when I put it together causing the board to hard reset. Can anyone see what I am doing wrong, or is it a bug?
I tried updating to 0.9.6 from 0.9.5, but it didn't help. I also tried rearranging the code as much I could, but it still seems to crash. Is it because I am creating a connection from within another connection? I'm not sure how I can get round that as I can't make the 2nd connection until the first has been done.
This is the result:
