İ want to connect with MATLAB and i make every thing at chapter 6. but it gives some error and dont connect on MATLAB:

When i restart bluetooth and after kh4server it says "ERROR: can't open serial port /dev/rfcomm0" is it normal? the terminal screen is below.


root@khepera4:~# /etc/init.d/bluetooth "restart"
Stopping Bluetooth subsystem: hidd pand dund rfcomm hid2hci bluetoothd hciattach.
Starting Bluetooth subsystem:
CSR build ID 0x0C-0x5C
Device setup complete
 ttyS1 bluetoothd hid2hci rfcomm.
root@khepera4:~# Waiting for connection on channel 1
root@khepera4:~# /etc/init.d/bluetooth "restart"

root@khepera4:~# ./kh4server
Khepera4 server program (C) K-Team S.A
Init ok...

Version = B, Revision = 5

Error: Serial port /dev/rfcomm0 could not be open!

i make the steps bellow like in chapter 6:

"Then restart the Bluetooth services with the command:
/etc/init.d/bluetooth restart"

but terminal writes:

"Device setup complete                                                           
 ttyS1 bluetoothd hid2hci rfcomm.                                               
root@khepera4:~# Waiting for connection on channel 1"       

and any change doesn't occure. So how can i make the step bellow:

"On the robot, launch the server kh4server (you must run it after having done the Bluetooth connection):
./kh4server"

Has anyone tried connecting multiple kheperaIV robots together to establish communication between the robots? Any guides or tips on how to do this?
