RobotDyn D1 R2 ESP8266 - WiFi not working (AP and STA)

Are you 100% sure that your connection details (see your 1st code share in your first post) are correct? I understand that what you posted here is mocked up, but check in your actual code.

I would suggest to try this code (a bit simpler than yours):

var wifi = require("Wifi");
wifi.connect("ssid", {password:"password"}, function(){ console.log("connected"); });

Then wait for "connected" message.

Also, make sure you do a wifi.save() to make sure that wifi settings are saved for after a power cycle.
