Hello Alexander Schmidt:

Which version of UHD and OsmoTRX do you have installed on your system?

What is your rx_gain setting?

[Openbts-discuss] B200 transceiver not working, no network
To: "ope...@li..." <

Hello,

I have an USRP B200 with 2 Vert900 antennas here.
I got OpenBTS 5.0 up and running and smqueue, sipauthserve and asterisk as
well.
The OpenBTS transceiver is somehow not working, so I installed
​​
osmo-trx, and software-wise it seems to work, but 2 issues remain:

- red LED at the transceiver, when I start services, blinking from time to
time
- no network visible (scanning for network with Iphone 4S and Motorola C118)

I use these commands to get it running:

sudo stop asterisk
sudo stop sipauthserve
sudo stop smqueue
sudo stop openbts

sudo osmo-trx -f
sudo asterisk -vvvr
sudo sipauthserve
sudo smqueue
sudo start openbts
sudo /OpenBTS/OpenBTSCLI

As soon as I start the openbts service with sudo start openbts, the
transceiver osmo-trx immediatly starts working and gives me that kind of
output:

..
NOTICE 3020118848 17:59:58.8 Transceiver.cpp:404:pushRadioVector: dumping
STALE burst in TRX->USRP interface
..

Where did I go wrong?
Will be very thankful for any advice!

Best regards,
Alex
