Hi everyone,

I recently purchased a SCC for my RPi and i still havent managed to get it working. After following absolutely every instruction on the net still no success. Ive reached to the point where i suspect the SCC module i purchased from Busware is defect. Could anyone kindly assist me in crosschecking if the Hardware is defect?

So far i have done as follows:

followed the instructions here step by step: http://blog.krannich.de/2014/08/busware-scc-in-fhem-einrichten/ that is:

Freeing up the serial interface:
in /etc/inittab and in /boot/cmdline.txt

Modified  /etc/init.d/fhem
in the switch start in included:


echo "resetting 868MHz extension..."
if test ! -d /sys/class/gpio/gpio17; then echo 17 > /sys/class/gpio/export; fi
if test ! -d /sys/class/gpio/gpio18; then echo 18 > /sys/class/gpio/export; fi
echo out > /sys/class/gpio/gpio17/direction
echo out > /sys/class/gpio/gpio18/direction
echo 1 > /sys/class/gpio/gpio18/value
echo 0 > /sys/class/gpio/gpio17/value
sleep 1
echo 1 > /sys/class/gpio/gpio17/value
sleep 1


After rebooting the led was blinking approximately every second.

I logged on to myip:8083/fhem/

added define SCC CUL /dev/ttyAMA0@38400 1234
attr SCC group CUL
attr SCC model CUL
attr SCC rfmode SlowRF
attr SCC room System
#EOF


But my SCC is stuck at the status opened and will not initialise

so i tried to manually connect to scc via the command screen /dev/ttyAMA0 but i can connect but if i try for instance "V+return" there is no response. i have tried changing permission of the port etc. nothing i even added user fhem to group dialout but nothing. How can i verify if SCC Hardware is working or not?

Any assistance will be will be highly appreciated.

Thanks inadvance

It looks like that the instruction you are referencing is taken from original busware.de-page: http://busware.de/tiki-index.php?page=SCC_Installation

first of all, is there a need to do "reset of 868MHz extension" also for Port 18? as the original installation manual says: "For normal operation leave it untouched or pull HIGH!" with an exclamation mark at the end  ;) what ever this means.

maybe it's worth to directly contact busware.de: http://busware.de/tiki-index.php?page=Impressum

I'm using the "stapelbarer CC1101" and did installation according to busware.de instruction "step-by-step", installation was done on a fresh installed Debian Wheezy without setting any further rights, for rfmode HomeMatic it worked directly.
