Can't run LimeSDR + OpenBTS

Hello, I tried to run OpenBTS 5.0 with my LimeSDR, on Ubuntu 16.04. I compiled osmo-trx from osmocom git (master branch) and built OpenBTS with “ B210”. How ever if i’m trying to run osmo-trx (I’m using sudo osmo-trx -s 4 -b 4) + OpenBTS, I got this errors:

LimeSDR support in OsmoTRX only supports use with EDGE (-e option).
