- Sat Dec 31, 2016 1:19 am #60188 Hey guys,

my nodelua coded with arduino code sorry beginner here. keeps crashing i think when i have multiple requests like if i request the page from web browser then from my phone but it doesnt always happen.

it just stops doing anything and doesn't show anything in serial or respond to request through the webpage.

maybe adding in a disable interrupt would work ?

Any thoughts / ideas would be appreciated

My code is as follows:

/////////////////////////////////////////////

/*
* This sketch demonstrates how to set up a simple HTTP-like server.
* The server will set a GPIO pin depending on the request
* http://server_ip/gpio/0 will set the GPIO2 low,
* http://server_ip/gpio/1 will set the GPIO2 high
* server_ip is the IP address of the ESP8266 module, will be
* printed to Serial when the module is connected.
*/
