efficient way of sending binary JPEG data over MQTT

[Tarkan DOGU]

Hi Folks,

How can I send efficently burst of JPEG binary image data over MQTT protocol? I don't want to use base64 encoding. I am publishing JSON data over MQTT.

thanks for advance...

Kind Regards, Tarkan

MQTT is “payload agnostic” - just send the binary jpeg data in the payload. No need to encode it.

Although if what you meant is that you want to embed JPEG image data as a field in a JSON payload, 

1) don’t, 

2) if you must, you will have to base64 encode it to a JSON string.

Maybe send the binary JPEG data on a different topic to the JSON ?
