I got the same error, after 10+ refreshes.
sorry, some examples need more tests, before it's writen in the doc.
the code below disconnect with client when payload is sent. may be it's better, still little tests made.

The TELNET example does not work and results in the module resetting every time..
The Web page example looks exciting at first.. but I noticed the browser returned the result "Hello NodeMCU but was constantly busy... and as browsers do, it retries the page.. and after 5 retries, the ESP-01 resets. Here's the output I monitored on the serial.
So here is the power up sequence and my init file getting an address from the router - all of that works..

So a quick test suggests it works - but in fact after a few refreshes - the unprotected error occurs and the board resets.
I got the same error, after 10+ refreshes.

the code below disconnect with client when payload is sent. may be it's better, still little tests made.
Code: Select all
srv=net.createServer(net.TCP)
srv:listen(80,function(conn)
conn:on("receive",function(conn,payload)
print(payload) print(node.heap())
conn:send("<h1> Hello, NodeMcu.</h1>")
end)
conn:on("sent",function(conn) conn:close() end)
end)
