Moitessier HAT No connection

[Luckbert]

Hello all,
I accidentally removed my connection of the Moitessier HAT hack. Unfortunately it does not come back. How can I get OP to show "ttyAMA0" again.
any suggestions?
Greetings Juergen

I did a little more research.
I can see the HAT under "/dev/ttyAMA0".
Why doesn't it show up in the Seriall app?

I can see the HAT under "/dev/ttyAMA0" << Where do you see this?

In SignalK

Edit:
I can create a new connection to this port in SK. Unfortunately, the error message comes up that the alias is missing.

In the serial app, the port does not appear at all.

Attempts so far:
Reinstall the app
Reboot with and without HAT

Greetings Jürgen

Can you show the error message? Screenshots would be useful including the one where you create the connection in SK.

Thanks

You say "Why doesn't it show up in the Seriall app?" but it does show up in your screenshot doesn't it? (Apologies if I am misunderstanding)

What happens when you try to assign an alias?

[Luckbert]

I can only see it because I added it manually in SK.
I don't see the device in the app, only the connection from SK.

How can I add an alias manually?

Deleted for clarity's sake

This would be the normal way if the device was displayed.

That is exactly the problem.
The device (HAT) is not displayed to me!

Only the connection (created in SK) is displayed.
