Official bladeRF forum

Hello,

I am attempting to run srsLTE UE on the bladeRFx115 board I have.

I am attempting to attach the UE to an LTE picocell

All of the debug messages on both sides imply that the bladeRF is properly decoding the eNB control channel, it receives the SIBs and then it trys to transmit a RACH request.

The Picocell never sees the transmit from the BladeRF.

I am powering the BladeRF with USB3.0 power. Is that acceptable? Or do I need a separate power supply?

Is there a way to easily verify that the board can transmit properly?

Thanks,

Dave

Dave,
I found it quite useful to have rtl-sdr and few dB of attenuators at hand. This way you can easily check if there is any output on the bladeRF. Additionally - if you'd had a splitter or such - you could potentially monitor TX output live.

Has the bladeRF enough output power to talk to LTE pico cell? The CW output is said to be +6dBm, but for wideband signal it will get definitely lower and will get more noise. So it may be actually responding but the signal cannot reach the tower.
