Using a bladeRF as a mini LTE base station. Got 2 Nuand bt-100 and 2 Nuand bt-200 bias tees however when I run my enb, they turn off immediately. I've read an older post on here about putting some command in a bladeRF.conf file, however I've tried that and nothing I do seems to be working. I am powering my bladeRF from an external power source, so it's not a USB issue (I don't think).

I'm using a bladeRF XA4. is there any fix to this?

Please show me your bladeRF.conf
Does the bladeRF itself turn off, or just the bias tees?

Are you on Linux? If so, does anything related to power show up in your dmesg logs?
You may need a powered USB hub if your PC can't provide enough power.
