Re: [paho-dev] Can MQTT publsih file example pdf or txt instead ofmesssa

Hi Peiyuan,

 

Quoted from: http://www.hivemq.com/blog/mqtt-essentials-part-4-mqtt-publish-subscribe-unsubscribe

 

"MQTT is totally data-agnostic, it’s possible to send images, texts in any encoding, encrypted data and virtually every data in binary."

 

All you need to do is get a byte array of the data you want to send, publish it and then convert that byte array back into the correct format in your subscriber.
