- Fri Apr 26, 2019 8:58 am #82044 Hi,
I have used a number of generic programmes to try to let me see my NodeMCU ESP8266 as a web server.

However although the code compiles uploads & runs and outputs its IP address - when I try to connect to it using a PC or phone using that IP address it cannot connect.

I have enabled debugging and when I try to connect I get multiple :
wifi evt: 7
printed out - so something is getting through to the NodeMCU but it is not responding.

Any ideas??

Regards
Melissa

- Wed May 22, 2019 1:16 am #82421 have a look to the wifi events

Code: Select allfrom "user_interface.h" ...
enum {
    EVENT_STAMODE_CONNECTED = 0,
    EVENT_STAMODE_DISCONNECTED,
    EVENT_STAMODE_AUTHMODE_CHANGE,
    EVENT_STAMODE_GOT_IP,
    EVENT_STAMODE_DHCP_TIMEOUT,
    EVENT_SOFTAPMODE_STACONNECTED,
    EVENT_SOFTAPMODE_STADISCONNECTED,
    EVENT_SOFTAPMODE_PROBEREQRECVED,
    EVENT_OPMODE_CHANGED,
    EVENT_SOFTAPMODE_DISTRIBUTE_STA_IP,
    EVENT_MAX
};


wifi event 7 just says your nodemcu wifi AP is being probed by some station around (likely the PC or the phone)
but you also say the nodemcu connects to your network
does that mean your nodemcu is configured as station + softap ?
two different interfaces with two different IPs and obviously two separate networks ?
which one is the web server listening on ?

sometimes, you're better off keeping things simple
and choose if you want your nodemcu to work as an independent AP or connected to your network
