[Bluez-users] rfcomm gives "no route to host"

[Marcus Mikolaiczyk <marcus.mikolaiczyk@carmedialab.de>]

Dear group users,

I got an embedded system using the Infineon Singlestone Bluemoon Module 
connected over UART. I can successfully start the device and scan for 
remote devices. I want to start rfcomm to provide a basic serial service 
  but probably I'm missing something to be successfull.
Kernel 2.4.19 (cannot be changed, cause it's a special port for the 
tricore 1130 microcontroller)
BLueZ Patch patch-2.4.19-mh18
Bluetooth support compiled in the kernel(no modules)
<*> Bluetooth subsystem support
<*> L2CAP protocol support
< > SCO links support
<*> RFCOMM protocol support
[*]   RFCOMM TTY support
<*> BNEP protocol support
[ ]   Multicast filter support
[ ]   Protocol filter support
Bluetooth device drivers  --->
	<*> HCI UART driver
	[*]   UART (H4) protocol support
	[ ]   BCSP protocol support
	< > HCI VHCI (Virtual HCI device) driver
