Hello,
I would like to add two (fake) mobiles by using the osmocomBB platform.
a single process of mobile app can serve several MS instances, see an example: https://git.osmocom.org/osmocom-bb/tree/doc/examples/mobile/multi_ms.cfg but you will still need to run two instances of trxcon: $ ./trxcon -s /tmp/osmocom_l2.one and $ ./trxcon -s /tmp/osmocom_l2.two --trx-port 6703 and finally, fake_trx.py needs to know about the second transceiver: $ ./fake_trx.py --trx MS@127.0.0.1:6000 After that you can manage both virtual mobile phones using the VTY interface: $ telnet localhost 4247 OsmocomBB> en OsmocomBB# sim testcard one OsmocomBB# sim testcard two NOTE: in the mentioned config file, change 'sim reader' to 'sim none' in order to use the virtual SIM cards. Good luck! With best regards, Vadim Yanitskiy.
