binding failed (trying next interface): Network error 98: Address already in use
main: bind error - no available interface

I have connected arduino uno to raspberry pi via usb port

and i run command

rotctld -m 204 -r /dev/ttyACM0 -s 9600 -T 127.0.0.1 -t 4533 -C timeout=500 -C retry=0 -vvvvvvvv

Something is already using the tcp port (4533) that rotctld tries to bind to, which probably means another rotctld is already running.
Run ps ax|grep rotctld or pgrep -a rotctld to find out.

Also, try copying the log and pasting it here as text instead of image, it is searchable and quotable.
Put logs etc in preformatted text using that button in this editor, or Ctrl-e.

thank you @SA2KNG,
I have run the commands and got following results

$ ps ax|grep rotctld

436 ?        Ss     0:00 /usr/bin/rotctld rotctld -m 202 -r /dev/ttyACM0 -s 9600 -T 127.0.0.1 -t 4533 -C retry=0 -vvvvvvvv > pause
 6111 pts/0    S+     0:00 grep --color=auto rotctld

and

pi@raspberrypi:~ $ pgrep -a rotctld


436 /usr/bin/rotctld rotctld -m 202 -r /dev/ttyACM0 -s 9600 -T 127.0.0.1 -t 4533 -C retry=0 -vvvvvvvv > pause

And what does that prove ?
Where is it started from ?
How did you install and configure it ?

I will provide you all the information and configuration I had made and What i am trying to do…

Hi Sir @SA2KNG,
I am currently on the project of my college to establish a ground station. For the mission, our ground station has to track the NOAA satellite automatically and also receive APT signal and decode it to the image.

For this, Hardware setup:

1. Raspberry Pi 4 Model B Rev 1.2, 4GB RAM:  can be access via ssh or desktop GUI login or real VNC. We are using desktop GUI login

2. Generic RTL2832U Rafael Micro R828D tuner

3. SatNOGS Rotor (only mechanical parts): rotor controller is self designed PCB including Arduino Uno, A4988, stepper motor and optical endstop sensor).

4. centre frequency 137 MHz V-dipole antenna with LNA-SPF5189Z 50-4000 MHz

Arduino Uno is diretly connected to the Raspberry Pi.

I don’t know what I missed. But I am still trying…

2. Manual tracking and decoding

After not getting good results, we tried to track using g-predict and GQRX installed on same Raspberry Pi to record the audio signal but not good results. And one more, we use NOAA APT decoder to decode the open source audio signal to image. And also tried GNU radio companion for visualisation of APT Signal Spectrum.

Upto this our ground staion is configured.!!

Thank you for your patience!

From what I gather, you are running rigctld from satnogs-setup configuration and that one is configured for type 202 and you want to change that to 204 ?
You cannot run rigctld manually when a service is configured to run it. The serial port will be busy and the tcp port will be in use already.
Also make sure the ttyACM0 or ttyACM1 is the correct one, it could also be ttyAMA0 or ttyS0. look in /dev for these.
