I'm trying to connect to an AP using:
SSID: this should be
password: 12345678

It fails to connect, but when I try with:
SSID: this should
password: 12345678

Code: Select all

#include <AntaresESP8266HTTP.h >

#define WIFISSID "this should be"                     
#define PASSWORD "12345678" 

antares.wifiConnection(WIFISSID, PASSWORD);

it works. Does NodeMCU V3 have a char limit to its SSID?

Max character limit is 32.

Avoid using spaces in SSID. Early Arduino ESP core had problems connecting to SSIDs with spaces. But it was resolved.
