Hi,
I'm also in favor for BTSAP. I personally find the protocol
fairly sane and like Kevin mentioned there is also already
the SAP server implementation in the osmocom repositories.

nice work. i like the idea that BTSAP is used by
layer23. this was my
intention when i added the sap_interface.c. not only that layer23 can
use softsim as reader, but also other btsap clients could use osmocombb
as reader.
I didn't even think of this option so far, but it's a good
idea and shouldn't be too difficult to add to the current
code!
to make this possible, the next step would be adding
the
btsap server socket to osmocon. (currently it only provides a socket for
L1CTL.) also layer1 sim reader would require to get a btsap compatible
interface.
there is only one thing i disagree: you implemented function in the VTY
to set the socket. this is already done in the configurations of each
mobile instance. i would suggest that you open the socket
(osmosap_init(ms)) at app_mobile.c when the instance is started (no
shutdown), in case the socket is given. then, if the mobile instance
starts working, the socket will be connected and the sim client will
read the sim as soon as the socket is connected.
I totally agree. I think the reason I did it this way was
for simplicity because when the reader and the SAP interface
are activated manually subsequently, the ATR command will already
have it's reply. If it's not done this way the mobile
application would have to wait for it to complete because
the process is fairly slow. But the cleaner way would be
app_mobile.c. I can work on that but will likely need some
time due to various other commitments at the moment.
Kind regards
Nico
