Hi,  
Has anyone tried to connect the new Arduino Uno R4 WiFi with HiveMQ? Is there a solution for certificates? On the ESP32, you can use WiFiClientSecure.h. Is there something similar for the Arduino Uno R4? Has anyone tested this? Thanks in advance.

Hi @bogdy, it’s fantastic to hear that you’re interested in MQTT and the HiveMQ broker. Welcome to the HiveMQ Community! We’re thrilled to have you join us.

> Hello @Sarunas I wanted to share with you a basic sample for the ESP32 that I’ve personally used on my device. This sample is designed to provide you with a clear understanding of how to effectively connect and publish a message to HiveMQ Cloud, so you can adapt the code to your needs. #include \<WiFi.h\> #include \<PubSubClient.h\> #include \<WiFiClientSecure.h\> //---- WiFi settings const char\* ssid = "TYPE\_WiFi\_SSID"; const char\* password = "TYPE\_WiFi\_PASSWORD"; //---- HiveMQ Cloud Broker set…

I hope this solves your issue

Best,
