Anybody have success initiating the LMS internal DC offset calibration? I'm getting large DC offset in the RX spectrum, typically -7 dB from full scale. I'm attempting to poke section 4.8 of the LMS FAQ http://www.limemicro.com/download/FAQ_v1.0r10.pdf to initiate the calibration. It seems to make no difference. I'm running the commands into the CLI like so:
./bladeRF-cli -s ~/cal.txt
Note I'm subtracting 0x08 from the upper byte of their spi_write to obtain the poke address. The lower byte is the data. I'll observe the spectrum in GRC, stop it and run the CLI, then restart spectrum. No improvement.
