# 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.
