MDL-Error in case of OsmocomBB+OpenBTS

[Pavel Baturko]

Hi,

I tried to use OpenBTS 2.6 and OsmocomBB phone works fine with it! Seems
that something wrong with OpenBTS 2.8.. But "usual" phones works with it.

Holger, thanks for your answer, I'll try find problem source.

All, does anyone use OpenBTS 2.8 with OsmocomBB?

Thanks,
Pavel
