Re: [Discuss-gnuradio] Transmission issue in USRP N210

[Marcus Müller]

The other Marcus here, I was the one that said something about the LEDs:

If your N210's transmit LED is not on, then openBTS simply did not instruct the USRP to send samples.
Thus, you will have to fix the problem on openBTS side. I'm pretty sure we went through all the diagnostics that made sense, and your USRP and UHD are working fine.

Greetings,
Marcus

Hi Marcus,

Can you ping the N210?

Yes. "ping 192.168.10.2" works fine.

If you use: uhd_usrp_probe --args addr=192.168.10.2, What happens?

"uhd_usrp_probe" also works fine. Couldn't check with --args. I am away
from the board now for few hours. Until then...

Is your ethernet interface configured for 192.168.10.1 ?

Yes. Configured statically in "/etc/network/interfaces" file.

Thanks,

 Hi all,

 I have recently installed openbts-2.8 on a banana-pi (Processor: armv7)
board to work with USRP N210. Had all the pre-requisite installations and
procedures been done, I noticed that, the transmitter is not working.

 Though this issue seems to be related with openbts but since they are
not responding, I would like to have some suggestions from you to resolve
this issue.

 In a previous thread 'Marcus' has stated that LED A is not working because
openbts is not talking to USRP. i.e. USRP is not configured to receive
samples.

 Is he pointing to a receiving issue (probably I was looking for a
transmission issue) or am I the one who is confused?

 Can anyone please shed some light on this.

 Thank you.

 Best,
Zamrath Nizam
