YateBTS / Connecting YateBTS to FreeSwitch
« on: February 11, 2017, 11:07:27 AM »
I have currently set up YateBTS as an extension in FreeSwitch and can call from YateBTS anyone in FreeSwitch however when a voip phone from freeswitch calls the number of the extension YateBTS it does not work because freeswitch does not know which yatebts phone to send the call to.  How do I setup the Sip To: header from freeswitch so I can select which internal number to call?

YateBTS / YateBTS Excessive TOA Errors
« on: February 04, 2017, 02:51:45 PM »
I have had a working YateBTS setup for a month now, haven't used it in 2 weeks but today when I turned it on the handsets could connect but on the iPhones it said "No Service" on the top bar.
In the verbose logs it spams excessive TOA errors:
The version of YateBTS is from here:

Heres the logs on max verbosity:

And heres my bladeRF cli version:
Code: [Select]
root@openbts-VirtualBox:/home/openbts# bladeRF-cli -i
bladeRF> version

  bladeRF-cli version:        1.4.0-git-unknown
  libbladeRF version:         1.7.2-git-unknown

  Firmware version:           1.9.1
  FPGA version:               0.1.2


Any idea what I am doing wrong?

EDIT: After further investigation this issue appears to go away when the band is changed to GSM900 (Previously was GSM850)

YateBTS / BladeRF getting hot
« on: January 05, 2017, 06:28:09 AM »
After getting YateBTS running the BladeRF gets hot, especially on the metal part over the radio circuits, is this an issue and does it need cooling or is it a software issue?
The bladeRF is connected to GSM 900/1800 antennas with a little spiral in them.  (The ones you buy for your car with the magnetic base)
And hot I mean hot to touch, it wont burn you but unpleasant to touch

Also, to increase the GPRS Speed, will increasing the Max Downlink+ Uplinks help?  Do these correspond to timeslots and do they only use TCH timeslots?  Like I have my BTS setup with a C0, a C7 and the other 6 are TCH, so does this mean I only have 6 GPRS channels or can GPRS also use the C7 and the C0?

YateBTS / RX Timestamp jumped

I get the RX Timestamp jumped error spammed when I do yate -s and phones of course can not see it.
Any idea what is going on? Ubuntu 12 LTS and BladeRF with latest BladeRF-cli software

YateBTS / GSM Identity Shortname
« on: October 30, 2016, 02:37:22 PM »
Hello everyone,  I am interested in setting up some GSM BTS stuff for a project I am working on.  I tried 2 years ago with OpenBSC but ended up wasting 800 dollars in ip.access NanoBTS equipment because it did not work since whenever a MS connected to it it would throw a "Segmentation Fault".  This time I want to try the alternative, and because OpenBTS has not gotten an update in years I think development has moved on to YateBTS.

However because I live in Greece and it has been difficult to acquire the GSM license there are several limitations and one of those is I need to use a specific Shortnames for the network to distinguish it from the other operator's networks (in addition to having different MCC MNC and of course a free ARFCN!).  However I have been a little worried since I read somewhere that changing the GSM.Identity.Shortname does not work in YateBTS even if it works in OpenBTS.  Can someone with a working system confirm this in the Public Release?  I don't want to spend another 420$ on BladeRF equipment and not be able to use it because of legal issues.
