unscramble BISS channel problem

[mgelecomnet]

Hello
I had trouble to unscramble the scrambled channel with the BISS code
the channel unscrambled with AutoConfig and everything is OK, but it doesn't work with manual configuration.
could you help me for Channel parameters?
///////////////------------------------------
this is auto config that works
card=0
freq=11881
pol=V
srate=27500
delivery_system=DVBS2
autoconfiguration=full=
autoconf_radios=1
scam_support=1
scam_const_key=117,00:00:00:00:00:00:00:00,11:11:11:33:11:11:11:33
multicast=0
multicast_ipv4=0
multicast_ipv6=0
unicast=1
ip_http=0.0.0.0
port_http=4242

//////////////------------------------------------------
this is manual config that does not work
card=0
sap=0
freq=11880
pol=h
srate=27500
delivery_system=DVBS2
ip_http=0.0.0.0
port_http=4242

scam_const_key=117,00:00:00:00:00:00:00:00,11:11:11:33:11:11:11:33

#FOR_EACH

new_channel=
name=IRIB VARZESH
ip=224.8.0.1
port=2000
service_id=117
pids=117 1170 1171

For manual channel configuration i think you need to provide pmt_pid parameter.

Dear @kslimani
thanks to reply
Iv added this line to config file but no unscrambling
pmt_pid=117
is there parameter for desca? force to use desca!!

I am not sure (i tested softcam only once a long time ago), the software descrambling doc. and scam parameters may give you some hints.

I can clearly tell that BISS decoder has no knowlege about manual or auto configuration, it just decrypts traffic passed to it.
So manual channel may not be properly configured. It's better to write such config for FTA channel and test it, and then just replace pid and add BISS key.
