It would be really handy to have optional retain flag options in UIFlow to choose when you want a published message to be retained by the MQTT broker. This is useful in that any retained messages are always accessible in the broker (different from the QOS delivery options).

Thanks!

Hi,

I picked up a RCA Module 13.2 and attached it to my Core2. I was able to generate tones (programming in arduino) using the internal Core2 speaker, but when I configure it to use an external speaker I'm not getting any signal out of the RCA Left or Right Audio outputs.

It could easily be a programming issue, but wanted to ask if anyone knows if this module can be used to generate tones?

Thanks!
