mqtt authentication

[Hubseba]

Hi,

is it possible to use mqtt authentication? I want to send the MQTT messages to a protected (User & PW) Mosquitto Broker

Greetings Sebastian

Maybe you can.

I don't have a protected (User & PW) Mosquitto Broker so I can't test it.

Can you show how to install the protected (User & PW) Mosquitto Broker?

Try latest.

Hi, a quick question about the broker, is it in deaufult on the sae ESP, or whitch I want on a seperate device? And second, my flashing attempts failed several times, even with different boards (esp32/esp32s2). Error.txt As a newbie in ESP-IDF I can't get ahead of this error Thanks

What is sae ESP?

And second, my flashing attempts failed several times, even with different boards (esp32/esp32s2).

I think this is the cause. Path too deep.
