Message-ID: <CA+x5dP-1UcRBNwfz2580rqmd_gYatPK0Kz4a4QV+0PfmTxT1cQ@mail.gmail.com>

Hi,

I try to use the gmr1_rach_scan flowgraph, but did not succeed.

I am always getting this error:

Traceback (most recent call last):
  File
"/home/peter/Radio/Thuraya/sylvain-gr/osmo-gmr/gr-gmr1/apps/gmr1_rach_scan.py",
line 22, in <module>
    from gnuradio import gmr1
ImportError: cannot import name gmr1

Anyone can help me how to compile and install correctly the needed blocks
for the flowgraph?

Thank you.

The block is in the gr-gmr1 repo .. you build it with cmake like any
other GR OOT.

Although I don't think I ever ported it to gnuradio 3.8 so it might
need adaptation for that.
Also it doesn't support mixed prefix install so you need to install it
in the same prefix as your gnuradio.

Cheers,

   Sylvain

I am using gnuradio 3.7, the build process stops with the following error,
and i really don't know why,
would be nice, if you, or anyone else can help me.
Thank you!

Someone can tell me what the base frequency for s-band is, to calculate the
arfcn.

I  found this info, but i am not sure  what is ul/dl, and if the
frequencies are correct.



2.170.000.000 - 2.200.000.000

GmPRS != GMR-1-3G
GMR-1-3G introduced new FACCH3 which is non-existent in GmPRS.

What satellite system are you looking at ?
I don't actually know any using GmPRS AFAIR.

1980 is Uplink
2170 is Downlink

Look at http://git.osmocom.org/osmo-gmr/tree/utils/gmr1_rx_sdr.py?id=f5bdb26c9499424518eaebf79d9c92399a1c6c9a#n71
This is  a python class that can comput ecenter frequency of any
channel. (any width, any band, any ARFCN).

Dear list , i am still trying to compile the gnuradio blocks for the rach.

But the building stops after 52%.

Could it be that there is something wrong in the source code?

Anyone else already succeeded to build the blocks?

I am using Ubuntu 18.04.5 LTS, with gnu-radio 3.7, the compiler give me the
following error:

PDU_PORT_ID is supposed to be provided by gnuradio. Either your
version is too old and doesn't have it yet ... or maybe it's too new
and that symbol has been removed. Or maybe an include is missing ...
At least in 3.7.9 it's there : http://aws.pabut.org/gnuradio/pdu_8h.html#Macros

Yeah, there might have been some changes not propagated everywhere ...
just look at the function being called and how it's meant to be
called, fix should be obvious.

The content of that branch will definitly require you to dig into
stuff, it's _far_ from being a turn-key solution ... more like a kit.
And I haven't run it in a while ... (don't even have gnuradio
installed ATM, especially not GR 3.7 ...)

Cheers,

    Sylvain
