Recently I have bought a Bladerf x4 micro, just for playing with GSM. At the time of purchase I only had a very good feedback from Blade, but for bladerf1.
Starting with Yate, I have follow this https://nuand.com/forums/viewtopic.php?t=5094 and when I try I got lot of:

The second try was with srsLTE. It's compile good for bladerf2 but I can't view any new station, just once time I could find a new station, don't know why because srslte do no print any errors.
Thinking in calibration I have tried to re-calibrate my new bladerf
I go to https://www.nuand.com/calibration/ but 'Could not find serial number'
First try, the official documentation: https://github.com/Nuand/bladeRF/wiki/D ... Correction Meh, it's only for bladerf 1
bladeRF> cal lms
Error: Command requires FPGA to be loaded
Board: Nuand bladeRF 2.0 (bladerf2)
Serial #: xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
VCTCXO DAC calibration: 0x1d41
FPGA size: 49 KLE
FPGA loaded: yes
Flash size: 32 Mbit
USB bus: 4
USB address: 21
USB speed: SuperSpeed
Ok, lets try with Kalibrate, I knew it because I have tried with Hackrf, Meh ! only for bladerf1
Ok, another idea: Using LTE-CELL-Scanner as source for calibration, Meh ! only for bladerf1
I do not doubt that bladerf2 it's better than 1, but with a lot of cool software that doesn't work in bladerf 2, for me, bladerf 1 its more attractive
Having issues with the site, hardware, source code, or any other issues?
