I was able to subscribe via Wi-Fi using the AWS block.
However, when I turned off Wi-Fi with LAN Base connected, I could not communicate.

Thank you.
LAN Base's MQTT init block does not have an entry to register a keyFile or certFile like the AWS block.

... Maybe I have misunderstood the programming process itself.
How can I use LAN Base to connect to AWS via wired LAN?

Connecting to AWS using LAN Base

I am a product designer and have recently been learning programming.
I'm trying to use M5 Stack and UI FLOW for a simple IoT device prototype.

I want to connect AWS IoT Core and M5 Stack via MQTT and subscribe with M5 Stack.
However, I cannot use wireless LAN in that environment, so I want to use LAN Base for wired connection.
Recently an MQTT block for LAN Base was added to UI FLOW.
However, I can't set up a private key or certificate like the AWS block.
How can I program it?

For example, can I just connect the AWS block following the Init block for LAN Base?
In that case, I don't know what to set for the remoteIP.
