How to Check ROS for Messages Published in Spresense-Arduino

You are trying to edit the GNSS information receiving sketch in the Presense-Arduino sample, publish the received GNSS information as a custom message, and subscribe to another node.
However,

$rosrun rosserial_arduino serial_node.py

[INFO][1570687026.937388]: ROS Serial Python Node
INFO 1570687026.948129—Connecting to/dev/ttyUSB0 at 115200 baud

INFO [1570687044.061219]—Requesting topics...

I get this error.
Could you tell me how to solve this?
Thank you for your cooperation.

Why don't you lower the baud rate?
