Hi,
We have a Litecell 1.5 unit. It is updated to the latest packages on the nightly build and
configured to an osmo-bsc set up on an another machine.
On mobile phones, the network does not show the short or long name set, instead it shows
just numbers "09070" and calls can not be made.
This has happened to us before when there was problem with the clock calibration on the
BTS.
A GPS device is attached to the BTS, and when running cgps, there is a 3D Fix and a
correct GPS location coordinates show up.
The lc15 bts should be able to calibrate automatically using the lc15bts-mgr package,
however, it seems like it is failing to do so.
When we tried stopping the lc15bts-mgr service and start it manually to log the output by
running:
/usr/bin/lc15bts-mgr -s -c /etc/osmocom/lc15bts-mgr.cfg
We notice the following errors:
```

```
It seems the lc15bts_mgr service can not read the values from the GPS device for some
reason, can someone please advise what might be causing this issue?
Best Regards,
Rayan
