[srslte-users] ENB: Invalid Cell Parameters and Error Parsing Cell Info

[devifr]

Andre,

Here's the ENB & EPC config files, as they were the only ones that I had
modified.  With regards to the default config, I had not tried that.  I'll
look up the default parameters, load them back in and see what comes of it.

first found), "UHD" or "bladeRF"
# device_args:        Arguments for the device driver. Options are "auto"
or any string.
