the sync of multiple ccch_scan in burst_ind branch

bob
Hello List
   I am studying to start multiple ccch_scan simultaneously,but I meet some problem.
I do as following:
1.I have two C118, caonnect them to the same computer
2.dump the sniffer rom
        ./osmocon -p /dev/ttyUSB0 -s /tmp/osmocom_l2_0 -m c123xor ./sniffer.bin
        ./osmocon -p /dev/ttyUSB1 -s /tmp/osmocom_l2_1 -m c123xor ./sniffer.bin
3.start the ccch_scan of burst_ind
./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1
./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1

but there is always one ccch_scan
give the following output after some time.
        <0001> app_ccch_scan.c:296 GSM48 IMM ASS (ra=0x99, chan_nr=0x40, HSN=47, MAIO=4, TS=0, SS=0, TSC=2)

I think it is an syn problem, maybe caused by the usb bus. does anyone have the idea?

thanks!

Why are they using the same socket?

I am sorry.it is a a slip of the pen.

./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1
./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1


I actually use
./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1
./ccch_scan -s /tmp/osmocom_l2_1 -a *** -i 127.0.0.1

but still get the above problem!
