2 hops then gone - hackrf #5

Open uniformsierra opened 8 years ago

hiya, Dunno what has changed but when using the current build (22 May) all my HackRF scans only work for the first two hops. The scan runs without error, however when it is visualized there is data missing (blank) - see attached. The resulting CSV files have "-inf" values in them where these errors occur.

I rolled back to the last commit on May 3 and it seems to work fine (https://github.com/polygon/sdr-power/commit/94656eefc239f5d7ac4c6e0e9bcf63ab84e0eee6).

RPi2, Jessie Lite, HackRF One (f/w 2015.07.2), solid power supply, only device on bus, Sandisk Extreme micro SD card (21.1 MB/s write), hackrf_transfer test = 19.9 MiB/second. Also tested using maxrate=5000000 which gave the same corrupted data.

Any thoughts?
