Learn how to use MQTT Explorer to publish and subscribe MQTT Messages. I’ll cover step-by-step how to connect, publish, subscribe and disconnect MQTT broker with MQTT client. Also, we’ll test MQTT client-server communication. MQTT Explorer client is capable to connect with any IoT broker or server which support MQTT protocol. Here we’ll use Mosquitto which is a popular MQTT broker used in many IoT projects.

Hi, please check with configurations and setting section of any accidental typo mistake in server ip address or in port. Also, try then with other MQTT server and see if it's an issue with particular server rather than MQTTExplorer. I hope this may help. Good luck and best wishes!

bro can we a send a video by this method

@BINARYUPDATES 10 месяцев назад

Hi Karthik, the standard packet size of MQTT is just few hundreds bytes so it's recommended to avoid for sending big size of data like videos. But yes if you want you can send small size of video. But in order to compress that video size your picture quality may need to downgrade. I hope this answers your question! I will make video on this topic in future to show you how MQTT been used to send images and videos. Good luck and best wishes!
