haven't test this with IOS app yet.
Note: put ap in 11b/g mode only, will not work in 11n or 11ac mode.

Code: Select allwifi.startsmart(6, callback())

should be

Code: Select allwifi.startsmart(6, callback)

Thanks. I'll try tonight, but the API documentation may need to be corrected as it requires the "()":

Code: Select allSyntax

wifi.startsmart(channel, function succeed_callback())

Parameters

channel: 1~13, startup channel for searching, if nil, default to 6. 20 seconds for each channel.
succeed_callback: callback function called after configuration, which is called when got password and connected to AP.

Returns

nil

Example

    wifi.startsmart(6, cb())

Thank you, it will be fixed soon.

print(tmr.now()) realy uint32?
i see negative value - i't a bug or it's a feature? or i can't understand?

It's a uint32 in C, but when put it into Lua, it becomes a Lua Number type.
negative means bigger than 0x80000000.
don't know how to convert to unsigned in lua yet

- Fri Nov 21, 2014 3:05 am #3043 So I did some more tests this morning.

Examples from here: https://github.com/nodemcu/nodemcu-firmware

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..

and then here is where I add in the web page example


> srv=net.createServer(net.TCP)
> srv:listen(80,function(conn)
>> conn:on("receive",function(conn,payload)
>> print(payload)
>> conn:send("<h1> Hello, NodeMcu.</h1>")
>> end)
>> end)

and then here is the result...

but then wait... the browser of course gets the page again... and again. and....

So a quick test suggests it works - but in fact after a few refreshes - the unprotected error occurs and the board resets.
