now I'm trying to connect my Arduino Nano 33 IoT with my MICOM(Intel NUC).

First I checked the connection between MICOM and Arduino, it was fine.

Then I make rfcomm0.

$ sudo rfcomm bind 0 24:62:AB:B2:22:96[mac addr of Arduino] 1
$ sudo sdptool add --channel=1 SP
$ sudo chmod 777 /dev/rfcomm0

after I run rosserial

rosrun rosserial_python _port:=/dev/rfcomm0 _baud:=115200

it only shows this repeatly

[INFO] [1589269328.939973]: Connecting to /dev/rfcomm0 at 115200 baud

I have tried various ways but nothing works. Please help me..
