Uart plugin, no data out

Hello,

Unfortunately, nothing goes out of the GPIO14 (TxD0); the pin stay high; checked with oscilloscope.

How to troubleshoot ?

Thanks

Did you enable UART on the Pi?

enable_uart=1

Depending on your Pi model that might not be sufficient…

With Pi 4.

Tried: to disable hciuart. But nothing.

But sending text from the command line is ok !

Checking the port I got:
speed 9600 baud; line = 0;
-brkint -imaxbel

@9600 nothing but the it should be 115200.

Into my directory volumio-uart-metadata, it has the file vol-print.sh

What is wrong ?

Any idea ?
