still could not find the cell. when sim remove 1, it start to search the
network,but can't find cell 1. After type 'sim testcard 1' in telnet,it
did nothing. I entered "configure terminal>ms 1>network-selection-mode
manual" to trigger plmn search, still can't find the cell.
what is the right way to get the phone doing plmn search with sim card in
cfg file. what I done above is ok?
I compared the 2 trxcon log between mobile and cell_log, mobile just
could not find the cell. Any more suggestion about this? cell 1 already
locked. Is the default cfg(osmocom-bb/doc/examples/mobile/default.cfg) ok?
or do you need more logs ?
Thanks again!

I used osmocom-bb and grgsm with usrp b210 to

failed. The command is "./mobile -c

,"grgsm_trx -p 5075" .
When i used “./cell_log -A 1 ”, it could find
plmn 1-1 with arfcn 1
which is same with openBTS.
FYI, grgsm_trx does not implement any kind of power measurement. The
reported RSSI values are just random values between -120 and -100.
Because of that, cell_log may or may not detect cells.
But when test with sim testcard 1, it failed to
find the 1-1 cell. Could
anyone give any suggestion about this? Thanks a lot!
It's a good question why cell_log does find your cell, but mobile does
not. As a workaround, I would recommend using the 'stick' parameter in
mobile.cfg. Just add it like this:
ms 1
stick 1
...
This will force the mobile app to use ARFCN 1 and nothing else. This is
exactly what I am doing when running a virtual setup, for instance.
