Re: MS cannot connect; Location Update Request not received by BTS - OpenBSC

6 Feb 2017

I installed master branch now(4/feb/2017 at 18:30) and retry, but I can not
release channel and receive error in nitb.
I do not access to a external timing source like octoClock, do you use
external timing source? do you have a easy solution to check that?
My NITB log is like your log by 20170203014240662 and repeat. I retried
connecting about 10 min but nothing happened.

NITB log that repeat is:

  Dear Hossein,

 the mailing list is indeed the proper place to ask. If no-one replied to
 your
 question, it either means that no-one knows the answer, or that no-one has
 found the time to look into it. Don't be discouraged by that. Indeed I
 would
 prefer if you ask again on the mailing list instead of asking single mail
 addresses. I actually saw your mail on the list and did not know what to
 answer.

 If you ask your question on-list again (possibly once a week), it might be
 that
 someone will come up with either an answer or with more questions that may
 lead
 you to a solution...

 I sincerely hope that you will find a solution. It seems to me that it's
 merely
 a minor detail.
