YateBTS / Re: Problems with libusb!!
« on: March 24, 2016, 04:02:26 AM »
Ok, thank you for the reply anyway.
I was guessing if I'm wrong though because I'm trying to connect my phone but my sim's not unlocked.
Could this be the problem?
And if so, is there a way to see my phone's Location Update routine anyway?
(I mean, is there a way to find my phone's IMSI even if I cannot accept it/the phone cannot register to the network?)

Thanks marian for the reply.
Here's the output of the command with bladerf/1 as device.

I think raw data can be seen. What now?

I tried to reconfigure ybts.conf in the proper way and I've managed to gsmtap packets to wireshark.
Actually this does work but I'm not able to understand what happens with GSMTAP packets on localhost.
Should I give you a sample of it?

I've set snr_threshold to 4, 10, 100, 400 but nothing changes.
Anyway what do you specifically mean by 'bursts' and why they're 'not ok'?
Why does this antenna seem to drop them all?
The last try I made I got this:
Code: [Select]
2016-02-18_16:45:28.829099 <gsmtrx:NOTE> ARFCN[0]: Radio power off. RX: bursts=16754 passed=0 (0.00%) dropped=16754 (100.00%) (LowSNR=16754) ellapsed=9sec avg=1861.56 bursts/sec [0xb670ad08]

I don't know if this matters, but I've followed this page:

and I've noticed that my board (with the mbts rxgain command) cannot go above 30 dB.
I mean, if I run:
Code: [Select]
mbts rxgain 45I get:
Code: [Select]
current rxgain is 0 dB
new RX gain is 30 dB

I've also tried to follow this link:
with an error when I try
Code: [Select]
cal lmsonce loaded FPGA and I get
Code: [Select]
[WARNING @ lms.c:2997] DC Calibration (module=3) failed to converge.
I've also noticed that if I try to set
Code: [Select]
set rxvga2 8it doesn't allow me to set values higher than 6 dB.

Can this help with my problem?

Thanks in advance.

Some more hints:
- Try connecting the board using USB 3 if possible. You should get rid of timestamp jumps)
- Try using another phone (it doesn't matter if location update succeeds: all you want to see if some message arriving from phone)
- Try to put some distance between phone and board (let's say about 5m)
- Make sure the angle between TX and RX antennas is about 90 degrees

- No USB 3.0 ports at the moment, so it's not possible
- Using another phone doesn't appear to grant anything
- Distance seems not to matter in this case
- Put TX and RX antennas in the right position

Nothing happens, as usual.
I'm starting to guess if the rx module of the antenna isn't broken, 'cause it seems like the only problem.
In second place I've already tried using bladeRF-cli and receiving samples and it actually does work with this configuration.
Really weird.... :/

Still stuck here....
I don't know what to do more than this.

Tried with all GSM bands and much C0s..
I think anyway that I'm tied to GSM900 or, atmost, 1800.
Still gettin' nothing :(

Yes, the phone is seeing the network but I when i try to connect nothing happens and I have 'no network' on the phone.
How do I set a different frequency?

If you mean
I setted this param on ybts.conf but same result.

Ok so now that I got my nuand board back I tried yet again to get my phone connected to the network but it still doesn't work.
I tried to do the GSM tapping with wireshark but no messages seem to arrive on port 4729 neither tcp nor udp.
In addition I've got  a lot of timestamps jumps and adjustments.
A log can help maybe:

I broke my nuand board!!  :( :( :(
As soon as I get a bladerf back I will try to do some capture with wireshark..
Anyway I knew there was a command for openbts that was like 'tmsi' or something for doing that instead of using wireshark ('cause I don't want to do illegal stuff by mistake)
I was guessing if there is an equivalent in yatebts..

I guess for now it's better not to use the wireshark solution...
I have both print_msg enabled and debug at level 9 (for mbts, ybts and transceiver modules) but no gsm messages seem to arrive neither on the console nor the log.

I can see my network from my phone but when I try to register to the network nothing happens..
I cannot see any messages from yate (connecting to localhost via telnet) about gsm connections (registration tries or something..).

Should I post something to you (configs or logs)?

Hi marian, thanks for your fast reply.
Ok, I cannot register atm even if regexp is set to .* but that's not my problem for now...
I only have a lot of timestamp jumps... is it normal?
I have followed the guide on nuand wiki to set yatebts minimal configuration.
I'm connected on usb 2.0 and I changed the radio_read_priority to highest and radio_send_priority to high in the transceiver section on ybts.conf and increased priority on limits.conf to my actual user by setting
@admin hard nice -20
@admin hard rtprio 99

Anyway I have a phone that doesn't show me my IMSI so I'm not able to register it. Can I see my phone IMSI's without registering it?

First, I have to thank you for all your help you're giving to my project; i really appriciate it.

I managed to compile the file that was missing. Now yate runs well but I still get the same LIBUSB_TRANSFER_ERROR yet again.
Now. I tried the card on a linux notebook and it works all well.
Leds are flashing and I can see my network on the phone. I have now an issue: I cannot register my phone. I setted regexp=^* but my phone fails to register.

Before trying to solve the last problem I need to know the answer to this question that is, for me, the most important over all.
According to these informations, could it be an ARM (raspberry) related issue?
I.e. : will I ever be able to run yatebts on raspberry or not?

In addition, I have to solve this issue also, though.

Thanks in advance.

No, it's not compiled.
In radio folder i have:  dummyradio.cpp dummyradio.yate and ybladerf.cpp only.
What should I do to compile it?
