[srslte-users] Commercial eNodeB

[Andre Puschmann]

Mark,

we haven't tested the Lime Mini ourselves but have heard good stories
from other users. We've tested with the normal Lime and this works fine.
In general, the Lime works better in the sub GHz frequencies. Using the
default LTE rates is a good idea. Lime calibration is done automatically
in the newer LimeSuite versions.

You are likely having gain issues. Try to play with the Rx gain settings
in your case and send a log and/or console trace if it still doesn't
pick up the cell.

Cheers
Andre
