Hi, just wanted to let you know that now, after pulling and building latest gr and gr-lte, it worked. Don’t know if from pulling, or if from chosing F6 instead of F5 within grc. Should it work with life reception, or only from a file? Maybe I’ll have a closer look later, now on board the train I do not want to play with a blinkenlight piece of naked SDR electronics J Ralph.

Subject: Re: [Discuss-gnuradio] gr-lte updated to GNU Radio 3.7 API unfortunately there are no screenshots yet. I guess it is a good idea to add some. After the estimator, there should be 2 blocks: Decode PBCH and Decode PCFICH. They take the same stream. and work in parallel. Then after Decode PBCH there is supposed to be a 'Decode BCH' block. These blocks may need some time to generate because they consist of hier blocks. That's kind of the tribute that has to be paid for a clean flowgraph. If you opened a flowgraph with missing blocks, as far as I know, to make the missing blocks appear you have to close and reopen at least this particular flowgraph.

after opening and generating the hier blocks still the top_level.grc has missing blocks, at least LTE estimator outputs and unpack MIB inputs are unconnected, leaving a large white area in between. How should this flowgraph look like, is there a screenshot available somewhere?
Just wanted to put this all together in my lunch break, but seems too big for such a short break anyway :)
