From 9fa291dd2ba880be0a07c0c3fff1ce537bbee4d1 Mon Sep 17 00:00:00 2001 From: Sylvain Munaut Date: Thu, 1 Feb 2018 12:05:28 +0100 Subject: l1ctl_proto.h: define burst indication messages One burst indication message carries a single raw burst, forwarded to the higher layers from DSP. The burst bits are hard-bits (0 or 1) coming from demodulator, packed to 14.5 bytes. This is why we call them 'raw' - no bit correction nor deciphering is performed.
