Hardware

Esp8266/Esp32: esp8266

Hardware: wemos d1 mini

Core Version: 2.4.0, staging

Description

Hello, i'm trying to combine with ubidots. Problem is all dots in serial monitor after ap config.
I need to define the wifi settings, but there is the problem i think.

This is the problem i think (very noobish in scripting):

#define WIFINAME "WiFi.SSID()" // Your SSID
#define WIFIPASS "WiFi.psk()" // Your Wifi Pass

Settings in IDE

Module: Wemos D1

Additional libraries: UbidotsESPMQTT

#include <FS.h>                   //this needs to be first, or it all crashes and burns...

Your wifi is not connecting

But i am getting an ip address ?
When defining the wifi settings manually, no problem. But i want to use the saved settings to connect with ubidots. I think it is a problem with defining the wifi settings for ubidots.
