[SOLVED] FireBeetle 2 ESP-32E won’t connect to Arduino IoT Cloud

[v205]

Hi,

I figured out what was wrong: I accidentally copied a space at the end of the secret key

This is the solved issue.
I have just gotten a FireBeetle 2 ESP-32E.

I have tried to connect it to Arduino IoT Cloud. But I keep getting these errors:

ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to mqtts-up.iot.arduino.cc:8884

ArduinoIoTCloudTCP::handle_ConnectMqttBroker 1 connection attempt at tick time 14357

I can confirm that the wifi on the FireBeetle is working: I uploaded the example “SimpleTime” with my timezone and WiFi Credentials. And I got the current time.

I uploaded this with the Arduino IDE 2.1.0(Mac OSX Monterey 12.6.2). DFrobot’s board package did not work so I used this one.
[Espressif’s Official Arduino Core.](https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json 17)

I have selected Firebeetle ESP -32 as the board because using the FireBeetle 2 ESP-32E doesn’t work.

This is the sketch I uploaded when I got the errors. Note that I did not include the arduino_secrets.h and thingProperties.h in this post.

Thanks in advance.

  The following variables are automatically generated and updated when changes are made to the Thing

  int fanSpeedLevel;
  int VOCIndex;
  CloudRelativeHumidity relativeHumidity;
  CloudTemperature temperature;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.
