    # Using the bladeRF bias-tee is royally annoying. Opening the bladeRF turns it off,
    # and the API for turning it back on isn't exposed in SoapySDR. Using the configuration
    # file works, but breaks FPGA loading since bladeRF-cli then attempts to turn on the
    # bias-tee before loading the FPGA. Using the configuration file to load the FPGA
    # works the first time and then crashes until the bladeRF is unplugged and plugged back in.
    # To work around these assorted bugs, we flash the bladeRF from an empty directory where
    # bladeRF-cli won't find the configuration file, and let it boot the FPGA from its flash, 
    # which seems less buggy/cumbersome than the other options.
