Hi All,
I am a beginner at nodeMCU and am trying to execute a simple GET request. Take a look at my code:



(You can ignore the timers if you like, they were just part of some attempted debugging.)

This code, when run using dofile, does not print out the contents of google.com. However, when I copy/paste the last line after running the dofile, and run it directly in the console, correctly prints out the webpage. What could be going on to cause this line to run in the console but not in lua files?

Thanks.

Hi,
I spent also a lot of time with same problem.
Running from CLI it worked , not as a program.
It was really strange, when I dofile("..lua) - file which consist from :
conn=net.createConnection;
conn:on("receive"..);
conn:connect(..))
it reports (with DEBUG functionality)

socket_connect is called.
....
net_socket_connected is called.

and later I dofile("..lua") which consist from
conn:send("GET...) and it works as expected

if all 4 function calls were in one lua file it didn't work.

it reports
socket_connect is called
only



BUT !
conn:send() encapsulated with conn:on("connection",function(conn,blabla) conn:send(..) end)
WORKS

If i understand the FW changes that have occured---
You can use consecutive sends with FW 0.9.6 and prior
Later Firm Ware issue 1 send

wait for call back then issue next send
repeat until last send

wait for call back then issue close

FYI limit sends to >= 1459
