Good idea! I'll write a brief description, how to run on SDR
and the road map of the project.

Well, there are many. Some points from my TODO list:

  - Restructurize the project to have a common include directory
    for both 'host' and 'target' parts. I don't like the current
    problem with 'l1ctl_proto.h': we have several symlinks because
    the '$(top_srcdir)/include' is out of include path.

  - Extend the L1CTL protocol to have a capability to request
    some information about L1 platform, e.g. TX_SUPPORT,
    FHSS_SUPPORT, SIM_SUPPORT, PHY_TYPE, etc.
    See http://osmocom.org/issues/1461 for details.

  - Finish Harald's work, related to getting rid of outdated copy
    of libosmocore inside OsmocomBB. Some things are still require
    careful testing after migration to newer code.

  - Since we have some good updates in Osmcoom gapk, it would be
    cool to have audio playback and recording implemented in mobile
    application. This way, it will be possible to speak exactly
    from PC running the GSM L2 and L3 stack.

  - Write a simple (the most things already implemented) tool,
    aimed to provide TDMA clock indications from existing BTS.

I'll be happy to see any opinions and additions ;)

With best regards,
Vadim Yanitskiy.
