[Hackrf-dev] HackRF TX does not stop after stopping flowchart

[Scott Davis]

I discovered the same thing while messing around with “transceiver” ideas a couple of months ago.  Although it’s not quite as obvious, the same applies to receive mode when stopping a GRC flowchart — HackRF keeps “receiving”  to some extent.  Check the RX LED.

I had two completely separate flowcharts, one TX and one RX, and manually switched between the two (3 or 4 clicks).  It only takes about a second, and I succeeded in making several two-way contacts that way (with volunteers down the hall, so far…).  When each new flowchart is started, it reinitializes the HackRF.  At the end of the session, I just hit the “reset” button to cancel whatever action is in progress.
