RaspberryPi timed out

I installed Python API of Meshtastic (v1.2.95) to my Raspberry Pi 4

I also connected TLoara v2.1.16 ( PaxCounter, Mesh firmware v1.2.65) via GPIO

When I running such command
meshtastic --port /dev/ttyS0 --info
I get the message on the board screen:
Unpowered…
Serial connected

But meshtastic CLI prints the error message:
Exception: Timed out waiting for connection completion

Is there way to establish connectivity in between?
