The idea is:
Add the ability to send binary files to MQTT topics.
My use case:
OpenWeatherMap icons for weather conditions are available via a simple link. It would be useful to serve the icon along with weather data over MQTT.
I think it would be beneficial to add this because:
IoT devices / apps can fetch the icons without needing access to the internet and by using the same protocol (ie not switching to URL, FTP, etc). It’s a little thing that adds simplicity and security.
Any resources to support this?
Binary data is part of the specification. The mosquitto_pub man page describes how to do this with the CLI app.
Are you willing to work on this?
I wish I was a better programmer! I will be poking at this, but I fear it’s more than I am (currently) capable of.
