YateBTS / Re: YateBTS with bladeRF x40 : no visible network

Yes, I see the same but after that it seems that the radio is up & running. What does the poweroff fault mean and what is causing it?

YateBTS / YateBTS with bladeRF x40 : no visible network

« on: December 05, 2014, 11:34:42 AM »

Hi All,

I've just received my bladeRF and started to dig into YateBTS. I've installed a fresh Ubuntu 14.4 virtual machine in Parallels on my Macbook Pro (Yosemite, HiSpeed USB) and did all the stuff described in the 'Installing' and 'Prerequisities' documents on the YateBTS wiki. I've managed to compile and install all the stuff and after doing some initial ybts.conf configging (Dect Guard Band, 1800, C0=885) etc I started Yate.

To me it seems yate is happy, from yate.log:

The bladeRF blade has blinking LED1 and LED3, afaik indicating it's TXing and RXing. But whatever I do, I see no network on my testphones (iphone6 and Nexus5).

What puzzles me is I see a lot of:

I'm not sure, but to me it seems the software is not receiving all stuff (in time), maybe due to USB2?

Any fingerpoints are appreciated. What is needed to make sure the bladeRF is correctly transmitting and is visible for a mobile station?
